How to watch UK/British television in Romania

How to watch UK/British television in Romania

 

If you live in Romania you've probably seen adverts to get UK TV channels for a monthly fee without a satellite dish, using the internet. You might think it's all a bit naughty like illegal card sharing - well, it's not! Read on...

 

One of the things Brits in Romania miss is their dose of UK telly - Corrie, Eastenders and all the rest! Until recently the only real option to get up to date fixes of your favorite UK programmes here in Romania was to have a huge satellite dish costing thousands - or by sharing a big dish with several homes/apartments, which is a much more economical option.

 

However, with the advent of all the FREE online catch up TV services in the UK (BBC iPlayer, ITV Player, Sky Player, 4OD etc.) and of course live streaming of many UK channels, the internet has become a cheaper way of getting your UK Telly - assuming you already have a broadband internet service.

 

The Problem

 

The TV broadcasters in the UK are not supposed to provide their services outside of the UK - for many reasons, not least because they only pay programme makers for the right to show the programmes in the UK. What they do is check where in the world you are connecting to the internet and if you are not in the UK, you don't get to watch!

 

The Solution

 

Make it look like your computer is connected to the internet in the UK! It's all very complicated to explain but it can be done by subscribing to a service which, once set up, will make the UK TV websites think you are actually in the UK and let you watch the programmes. They are called "VPN's"  It's all very safe and doesn't slow your computer down, bombard you with adverts or anything like that (except of course for the adverts on the telly programmes!!).

 

VPN are the better option because Proxy Server services don't always work for all TV services.

You need to decide how you will link the

You need to decide how you will link the Digipass devices to your users. Manual Assignment (see 5.3)The administrator manually assigns a Digipass device to each user in Active Directory. Then you physically give the Digipass with the correct serial number to the person. Self-AssignmentYou give each user a Digipass device. You instruct the user how to "activate" his Digipass the first time he will use it. This is called "self-assignment". They will need to enter the following string in the password:No PIN = "SERIALNUMBERpasswordOTP" PIN active = "SERIALNUMBERpasswordPINOTPIn this document we use the "self-assignment" mode.See page 48 of the VACMAN Middleware Product Guide.pdf for more info

A VPN or Virtual Private Network vpntraffic

A VPN or Virtual Private Network is a method used to add security and privacy to private and public networks, like WiFi Hotspots and the Internet. VPNs are most often used by corporations to protect sensitive data. However, using a personal VPN is increasingly becoming more popular as more interactions that were previously face-to-face transition to the Internet. Privacy is increased with a VPN because the user's initial IP

address is replaced with one from the VPN provider. This method allows subscribers to attain an IP address from any gateway city the VPN service provides. For instance, you may live in San Francisco, but with a VPN, you can appear to live in Amsterdam, New York, or any number of gateway cities.

A VPN network creates a secure connection over a public network i.e. the internet being one of the most important requirements of daily lives. The encryption for such a connection is provided by using algorithms for having security and the establishment of a reliable connection which is not possible in the case of a proxy server. There are a number of VPN protocols in use that secure the transport of data traffic over a public network infrastructure. Each protocol varies slightly in the way that data is kept secure. IP security (IPSec) is used to secure communications over the Internet. IPSec traffic can use either transport mode or tunneling to encrypt data traffic in a VPN. The difference between the two modes is that transport mode encrypts only the message within the data packet ...

Do you want buy from the kindle store at US prices.

 

used the VPNTRAFFIC to give me a US IP address. This caused Amazon to show me the US prices. I then created a new account and registered it in Kindle for PC. I then tried to order a (very cheap) book at the US price. If i gave my real billing address it would change the price. However when i gave a bogus US billing address it accepted my non-US VISA card without complaints and the book showed up correctly in Kindle for PC.

VPN concentrator and a VPN server

A VPN usually consists of two components: a VPN concentrator and a VPN server. The VPN concentrator generally receives packets on the  OSI Layer 2, 3 or 4, encapsulates and encrypts the packets into network frames, and then sends the network frames to the VPN server via public networks. The VPN server receives the network frames, decrypts and decapsulates the network frames into the original packets, and then sends the original packets to the destination computer. Similar things happen to the returning traffic. People on public networks may capture the packets, but they cannot decrypt the network frames. The network traffic is protected by this process. Internet Protocol Security (IPsec) is one of the VPN technologies and is a suite of protocols. It receives packets on the OSI Layer 3 (IP Layer) and secures the packets inside the IP layer. IPsec uses Internet Key Exchange (IKE) protocol to generate security keys and to handle security key exchange between the VPN server and the VPN concentrator, and uses Authentication Header (AH) or Encapsulating Security Payload (ESP) to encrypt and to protect IP packets. IPsec has strong security and it has already been integrated into the next generation network (IPv6). Layer 2 Tunneling Protocol (L2TP) is one of VPN protocols. It receives packets on the OSI Layer 2 (Data Link Layer) and secures the packets inside the OSI Layer 5 (Session Layer). It does not provide strong authentication method by itself and often the L2TP packets are sent inside IPsec for a better security. Compared with current VPN technologies, a VPN that transfers Layer 2 packets has a better range of applications as it can transfer almost all kinds of Internet packets: IP packets, non-IP packets (such as IPX packets) and Layer 2 packets (such as PPP packets [39]). This thesis focuses on VPN technologies that transfer Layer 2 packets.

cable TV vpn

Distribution. In a market worth billions annually,1 a cable operator such as Comcast, Time Warner Cable or Cox is usually the lone local cable operator, having long ago received governmentbacked monopolies and guaranteed returns.2 In the 1990s, satellite operators were able to compete more effectively, largely through regulatory changes such as a compulsory copyright license for broadcasting and program access rules requiring cable operators to make their content available to rival satellite providers.3 This decade, after years of promises, telephone companies finally entered the cable TV vpn  business, with the benefit of regulatory changes,4 though their deployment plans will target no more than 40 percent of U.S. homes.5 So far, government attempts to increase competition in the cable market have resulted in only four players at most, with the local cable operator still dominant. And entry barriers are so high that additional facilities-based competitors are not expected to emerge. This limited competition and insurmountable barriers to entry have resulted in even higher prices,6 with few advances in formats and cuts in capital investments even as the cost of technology falls.7 Broader competition is sorely needed. For  consumers, the distribution market is local not national. On average, the local cable operator retains roughly 68 percent of the local cable TV consumer market, according to the most recent Federal Communications Commission study in 2007.8 The satellite operators DirecTV and EchoStar roughly split most of the rest, though phone companies are making inroads.9 More recent figures, which are not available, would likely show that Verizon's Fios product has taken some market share, though Fios is available only in few, generally wealthy, and densely populated communities.10 These local markets are oligopolies; indeed, the cable operators' 68 percent share likely signifies monopoly power.11

Netflix Argentina VPN iphone

One way to see how strong these switching costs are is to examine Netflix churn rate.  Churn is a marketing term referring to the rate at which customers leave a product or service.  A low churn is usually key to profitability because it costs more to acquire a customer than to keep one.  And the longer a customer stays with the firm, the more profitable they become and the less likely they are to leave.  If customers weren't completely satisfied with the Netflix experience, many would be willing to churn out and experiment with rivals offering cheaper service.  However, the year after Blockbuster and Wal-Mart launched with copycat efforts, the rate at which customers left Netflix actually fell below four percent, an all-time low.  And the firm's churn rates have continued to fall over time.  By mid 2008, rates for customers in Netflix most active regions of the country were below three percent, meaning Netflix Argentina VPN iphone fewer than three in one hundred Netflix customers canceled their subscriptions each year9.  To get an idea of how enviable the Netflix churn rates are, consider that in 2007 the mobile phone industry had a churn rate of 38.6%, while roughly one in four U.S. banking customers defected that year10.  All of this impacts marketing costs, too.  Happy customers refer friends (read free marketing from a source consumers trust more than a TV commercial).  94 percent of Netflix subscribers say they have recommended the service to someone else, and 71 percent of new subscribers say an existing subscriber has encouraged them to sign up.  It's no wonder subscriber acquisition costs have been steadily falling, further contributing to the firm's overall profitability.

The ,channel quality could be severely degraded due to interferences ,from other neighboring APs. Moreover, each individual ,customer's perception about the WLAN performance can be ,different. Someone may even complain about her/his WLAN, ,which operates normally. The operator needs to measure how the ,WLAN performs quantitatively to decide a proper remedy. If the ,performance of the air-link is considerably poor, the service ,provider should install a new AP additionally or replacing the old ,one or change the allocated channels of other neighboring APs. ,That is, the process to measure the performance over the air link ,can be an initial step for satisfying the customer and provisioning ,the network.  ,The architecture for building this function is based on a 3-way ,handshake among Dr. Nespot manager, Dr. Nespot agent, and ,client station. The manager at the remote node or near associated ,station sends an initial PDU, which requests the performance ,measurement, to an AP. Then,  the AP begins measuring the ,performance metrics, e.g., throughput, delay, and jitter by ,repeating dummy packet transmissions to a specific client station ,during a specific time interval. The results of measurement are ,calculated by client and sent to Dr. Nespot manager through the ,agent. ,4.

VPN systems use non-TCP/UDP

VPN systems use non-TCP/UDP protocol, or use privileged low (< 1024) ports (e.g. ISAKMP used by IPSEC uses port 500) that are often blocked by firewalls. This means that VPN clients can be unusable from many places like public hotspots, hotels and many GPRS connections. User mobility and remote access often do not work with a VPN model. The above limitations of the current VPN systems have been the driving force for the authors for the design of N2N. In a nutshell we ask: "Is it possible to have decentralised, network-administrator-free, secure and permanent network access with a single/uniform address regardless of the current user's location, local IP address and network type?".The authors  designed N2N  to give N2N users the ability to create dynamic private networks. As happens with community networks, users should be able to create their own overlay network which other users are invited to join. With VPN the network administrator chooses who may join the VPN and what interactions will be tolerated. N2N is somewhat similar to Hamachi [12], a popular application mostly used for creating private networks on which to play games. With N2N users can choose their IP address and the encryption keys, whereas with Hamachi this is not possible and all the security is delegated to Hamachi, making the whole solution weak from a security point of view.

VPN capable nodes

Media independent handover is an IEEE 802.21standards-based solution that defines access technologyagnostic interworking procedures. The IEEE 802.21working group, initially chaired by Ajay Rajkumarfrom Bell Labs, began work in 2004, resulting in astandard being approved in January 2009.The goal of MIH is to facilitate handovers betweenheterogeneous access networks through the definitionof a core set of services and components that wouldexist within both UE and throughout the network.MIH partitioned the services into three general categories: command, event, and information. Additionally,MIH defines a protocol for communication betweenMIH-capable nodes (e.g., mobile node [MN] to network, or network to network) that allows for coordinated efforts before, during, and after a handover.An MIH-capable node contains an MIH function(MIHF) that provides one or more of the core servicesto the upper layers (MIH users), and expects a minimum set of functions from the lower (link) layers. As shown in Figure 2, MIH users gain access to MIHservices through an MIH service access point(MIH_SAP), whereas MIHF gains access to lower layer

When building a VPN based on p-to-p overlays

When building a VPN (Ferguson et al., 1998) based on p-to-p overlays, connection-oriented (like ATM or frame relay, tunneling-on-IP techniques) scalability is a main problem, while VPNs based on MPLS are used to address scalability issues (as they are purely designed on the basis of connection-less, peer-based architecture). Since, a customer-site in a peer-based architecture requires the peer simply within a single provider-edge router in place of the entire customer-edge/provider-edge routers which are associated with the VPN that results in the reduction of large number of VCs. In addition, MPLS-based VPNs naturally use connectionless approach. The Internet is to be obliged its worth to its fundamental approach which is based on connection-less, packetswitching network topology (i.e., TCP/IP). Thus, it does not require any prior act to make association possible in a flexible and useful way among the hosts. In an IP-based connection-less setup the traditional VPNs require initial connection establishment process over p-to-p, connection-oriented overlay networks. When it utilizes under a connection-less environment it still can not get benefit from the connection simplification and service expandability offered by connection-less network. In contrast, if a connectionless VPN is built, to guarantee the network privacy the use of tunnels and encryptions are not required, hence it eliminates the considerable complications.

numerous ICMP packets have arrived

numerous ICMP packets have arrived within a small time interval; application-specific bufferoverflow attacks to obtain root privilege, such as  subverting an FTP server by a long "MKDIR" command, may require buffering and reassembling several packets before seeing the whole FTP command. A network-based IDS can detect such attacks by matching a sub-string, for example, the "phf" in " GET/cgi-bin/phf?," to identify those network packets as vehicles of a web server attack. When such kinds of potential hostile activities are detected, IDS will alert system administrators and may block the activity. The above examples describe the basic functions of a network based IDS.  In fact, the IDS model can be host-based IDS (HIDS) or network-based IDS (NIDS). HIDS is installed at a host to periodically monitor specific system logs for patterns of intrusions. In contrast, an NIDS sniffs the traffic to analyze suspicious behaviors. A  signature-based  NIDS (SNIDS) examines the traffic for patterns of known  intrusions. SNIDS can quickly and reliably diagnose the attacking techniques and security holes without generating an over-whelming number of false alarms because SNIDS relies on known signatures. However,  anomaly-based NIDS (ANIDS) detects unusual behaviors based on statistical methods. ANIDS could detect symptoms of attacks without specific knowledge of details. However, if the training data of the normal traffic are inadequate, ANIDS may generate a large number of false alarms.

There are several motivations for building VPN’s

There are several motivations for building VPN's, but a common thread in each is that they all share the requirement to "virtualize" some

portion of an organization's communications – in other words, make some portion (or perhaps all) of the communications essentially

"invisible" to external observers, while taking advantage of the efficiencies of a common communications infrastructure.

The base motivation for VPN's lies in the economics of communications.  Communications systems today typically exhibit the

characteristic of a high fixed-cost component, and smaller variable cost components which vary with the transport capacity, or bandwidth,

of the system.  Within this economic environment, it is generally financially  attractive to bundle a number of discrete communications

services onto a common high capacity communications platform, allowing the high fixed-cost components associated with the platform to

be amortized over a larger number of clients.  Accordingly, a collection of virtual networks implemented on a single common physical

communications plant is cheaper to operate than the equivalent collection of smaller physically discrete communications plants, each

servicing a single network client.

So, if aggregation of communications requirements leads to a more cost-effective communications infrastructure, why not pool all these

services into a single public communications system?  Why is there still the requirement to  undertake some form of partitioning within

this common system that results in these "virtual private" networks?

VPN Client User Guide for Windows

The principal goal of this paper is to provide best-practice information to interested parties for designing and implementing

Enterprise IP Security (IPSec) virtual private networks (VPNs). The SAFE white paper for large enterprises and the SAFE

white paper for small, midsize and remote user networks are both available at the SAFE Web site: http://www.cisco.com/go/

safe. These documents were written to provide best-practice information on network security designs. They include some

element of VPN configurations and design guidance. This document continues the discussion, examining specific design

considerations and best-practice recommendations for IPSec VPNs in networks today. Although you can read this document

without having read either of the two security design documents, it is recommended that you read the document most

appropriate to your network size before you read this document. For example, a business with a large network might look

at the enterprise SAFE white paper before reading this document. This exercise will frame the VPN conversation within the

context of overall security design. SAFE represents a system-based approach to security and VPN design. This type of

approach focuses on overall design goals and translates those goals into specific configurations and topologies. SAFE is based

on Cisco products and those of its partners.

This document begins with an overview of the architecture, and then details the specific designs under consideration. The

following designs are covered in detail:

• Remote-user VPN designs

• Small-network VPN design

• Medium-network VPN design

• Large-network VPN design (with extranet connectivity)

• Distributed large-network VPN design

A ZDDP tribofilm experiment consists of the following:

A ZDDP tribofilm experiment consists of the following:

1. The test chamber containing lubricant is heated while rotating the ball and disk in pure rolling with no applied load until the test temperature is reached.

2. Motion is then halted and the glass window is loaded against the stationary steel ball. An interference image of the window/ball contact is captured for subsequent analysis to determine the spacer layer thickness.

3. The glass window is withdrawn from the steel surface and a rubbing test carried out for a set duration at the set temperature. In this, the steel ball is loaded against the steel disk and the two are rubbed together in mixed rolling/sliding at low rolling speed to produce mixed or boundary lubrication. This generates a ZDDP tribofilm on the rubbed track of both the steel ball and steel disk.

4. Motion is then halted, the glass window loaded against the rubbed track on the stationary steel ball, and an interference image of the window/ball contact is captured. By comparison with the initial image, interference colors present can be used to determine the thickness of any solid-like tribofilm formed on the track.

5. Procedures 3 and 4 are then repeated over a total test time of several hours to obtain a series of interference images and thus maps of the variation of ZDDP tribofilm thickness on the ball over time.

It is important to note that the tribopair that forms the ZDDP film is the steel ball/steel disk sliding contact. The glass window is only loaded against the stationary ball to displace any supernatant oil and measure the thickness of the residual solid-like film present and this is done without rinsing or cooling the ball in any way and without removing it from the test apparatus.

The advantages of a network-based VPN

The advantages of a network-based VPN aretwofold. First, data aggregation and scalability areachieved by terminating all VPN sessions from clientsat the IPSS and transporting data packets over a single VPN session from the IPSS to the enterprise VPNgateway. Because the enterprise VPN gateway has toterminate only one VPN session, even when the number of VPN client sessions increases, the amount ofVPN session information—including security association (SA) information—that must be maintained atthe enterprise VPN gateway does not increase. Thus,data aggregation for VPN sessions is itself a valueadded service that an NSP can offer to its customers.Second, because packets are decrypted at the IPSS, it is possible to offer value-added services (e.g., firewallservice, URL filtering, and caching service) that require packet and application header inspection withinthe service provider network and then to offloadpackets that have to be sent directly over the networkwithout sending them to the enterprise. In contrast, aservice provider cannot provide these services to packets in transit toward an enterprise over an end-to-endnetwork, because the necessary packet and application headers are not visible in the clear in the network. Note that these services not only increaserevenue opportunities for NSPs, but also benefitenterprises by enabling them to outsource these services to the NSP

Framework for dynamic optical virtual private networks (VPNs): architecture and analysi

Optical wavelength division multiplexing (WDM) technology, which has a high bandwidth capacity, is becoming apractical reality with recent technological advances [1]. Suchnetworks are expected to play a dominant role in the nextgeneration networks. Currently, communication trafficcontains more and more types of traffic flows, includingmultimedia information, which has different delay and jitterrequirements from some non-real-time traffic. Thus, there isgreat diversity of service requirements among traffic flowson optical networks. All these requirements cannot be metby the currently deployed synchronous network technology(SONET/SDH). This motivates the consideration of opticalvirtual private networks (VPN). In optical VPNs, customerscan contract for a variety of network resources such as linkbandwidth, wavelength, or optical connection ports. Theoptical VPN service gives customers private ownership oftheir optical bandwidth, including the capability to control,manage, monitor and provision optical circuits, without theburden of maintaining a physical network infrastructure.Optical VPNs provide a new revenue stream for serviceproviders.A VPN is an overlay network that is built above a publicnetwork infrastructure, providing the VPN user with aprivate network using tunnelling, encryption and authentication mechanisms [2]. VPNs are gaining increasedacceptance due to their economic benefits and the maturingtechnology. VPNs may be built above different types ofpublic network, such as frame relay, ATMor the Internet.The primary advantages of VPNs over the Internet are theircost-effectiveness and flexibility. However, the disadvantages of VPNs over the Internet are lack of reliability andsufficient quality of service (QoS) mechanisms.Recently, there have been proposals to embed offlineVPNs over WDMoptical networks [3, 4]. The proposal in[3] requires that VPN users have pre-allocated all the lightpaths to different traffic streams. This is hard to handlewhen burst or no pre-planned traffic streams occur andrequires dynamic lightpaths setup, In this paper, we furtherexplore the problem of online VPN design, in particularWDMrouted networks [1]. The WDMrouted networkprovides an 'optical connection' layer which consists ofseveral lightpaths. A lightpath is defined as an all-opticalconnection from the source node to destination node,traversing several intermediate optical wavelength routingnodes.The basic difference between the online VPN and offlineVPN is that lightpaths in an online VPN can bedynamically set up and released when necessary; lightpathsin an offline VPN are pre-defined and cannot be changedduring the transmission process.An architecture for an online VPN over WDMisproposed and a preliminary study conducted. The networkarchitecture considered is as follows. A network providerowns an optical WDMbackbone network and providescapacity to users (e.g. large corporations) requiring VPNservices. A VPN is specified by a set of nodes that need tobe interconnected. The network provider accommodates theVPNs its objective being to maximise the total traffic ofVPNs and to optimise use of the backbone capacity. Theproposed architecture separates the different VPNs in theoptical domain by providing lightpaths with differenttransmission qualities to meet the different VPN topologies.Borrowing items from asynchronous transfer mode (ATM),we consider the following three types of traffic.Constant bit rate (CBR): CBR classified traffic is normallyintended for traffic with very stringent timing requirements.This type of traffic requires a constant cell transmission ratefor the entire duration of the connection.Variable bit rate (VBR): this service is intended for burstytraffic, such as transaction processing applications andLAN interconnection.Unspecified bit rate (UBR) and available bit rate (ABR):UBR traffic is for applications which send data across thenetwork with no guarantee when that data will arrive at itsdestination. ABR is similar in the sense that it makes use ofany available bandwidth and reduces the transmission ratewhen the network is congested.The QoS model proposed allows three types of VPN:static, optical burst switching(OBS) and alternative VPNs.The static type has a set of dedicated or shared pre-allocatedlightpaths to transmit its packets. This type has the highestquality of service and thus is only applicable to traffic withconstant bit rate (CBR). The burst type requires dynamically setup lightpaths when traffic streams with variable bitrate (VBR) have requests. We tend to set up the dynamiclightpath using optical burst switching (OBS). The alternative type provides a service to the traffic streams whichhas no guarantee, e.g. UBR or ABR traffic. Lightpath setuptakes a long time due to the two-way reservation methodadopted.There are several advantages for this architecture. First,by setting up lightpaths for the VPN traffic stream, packetsdo not need any buffer once they enter the optical corenetwork and flows can guarantee minimum delay andreliability.

MILLIONS OF PC users today are living dangerously-and I'm not talking about using their laptops in the tub. The risky behavior I have in mind involves using an unsecured Wi-Fi network.

Lots of people forgo security because they think it's too complicated or they fear performance problems. But now you can get the strong security that enterprises use, without encountering a lot of hassles. Using an unsecured network at home or at a public hotspot is unquestionably dangerous: It's not hard for someone to grab your passwords or other data under those circumstances.

Many business travelers and remote workers use a virtual private network to connect to their offices. A VPN shields the con tents of any Wi-Fi connection by encrypting the communication and routing it through a trusted network. Traditionally, setting up a VPN server on a home PC has been about as easy for most people as building a nuclear reactor in the basement. But new VPN tools now make this robust technology available to the masses.

If you frequently use public hotspots, VPN service from Mega Proxy (www.megaproxy.com) is a good security choice. It costs $10 for three months (a free version with restrictions is also available). MegaProxy's one weakness is that it protects only your Web browsing traffic and not other forms of communication, such as instant messages or P0P3 e-mail exchanges.

Home users can transform certain models of routers into power house VPN servers by upgrading the router's firmware. Sveasoft's Alchemy software (find.pcworld.com/46582), for example, replaces the original firmware in several models of Linksys home or small office Wi-Fi routers. The company charges $20 for a year.

Updating firmware is always slightly risky, because a botched up grade can turn your gateway into a doorstop; and installing Sveasoft's firmware will void the warranty on your gateway. But Alchemy can turn a plain-vanilla Linksys WRT-54G gateway, for example, into a truly robust security device.

Whatever else you do, take steps to secure your network. Save your risky behavior for something more fun, like skydiving.

Netronome Unleashes Suite of Software Application Kits for Flow Processing in Cyber Security Designs

Netronome, the leading developer of flow processors, announced the availability of a major upgrade to its Network Flow Management (NFM) software framework including new application kits for next-generation firewalls (NGFW), IPsec, intrusion prevention systems (IPS) and SSL inspection. Netronome's NFM provides a comprehensive suite of production-ready reference software for the NFP-3240 network flow processors (NFP) that accelerates a wide variety of cyber security applications to industry leading throughputs.

"Netronome's new software application kits provide an extensive set of building blocks for security applications," said Joe Byrne, senior analyst at The Linley Group. "That enables OEMs to focus on development of their applications, while significantly increasing performance with Netronome's flow processors."

Netronome's IDS/IPS application kit accelerates x86-based IDS/IPS applications through hardware-based packet classification, stateful management of flows, and an integrated, dynamic load balancer. The NGFW application kit augments the IDS/IPS use case with capabilities which allow policy enforcement and packet forwarding between multiple network segments using integrated L2 and L3 forwarding with network address and port translation (NAPT), IPsec VPN support and SSL inspection. Netronome is also making the IPsec and SSL inspection application kits available as standalone application kits for integration within other applications and use cases.

"Networking OEMs are designing 100 Gbps applications that require full visibility into all layers of network traffic, including encrypted communications," said Jarrod Siket, senior vice president of marketing at Netronome. "With Netronome's innovative, workload-specific processing architecture vendors can combine Netronome's flow processors and software application kits with standard x86 processors to bring high-performance security products to market quickly."

Protocol security (L2TP/IPSec), to connect remote clients and remote

Learn about the extensive support for virtual private network (VPN) technologies in Microsoft Windows using the resources on this page. An extension of a private network, a VPN encompasses links across shared or public networks. VPN connections use the connectivity of the Internet plus a combination of tunneling and data encryption technologies, such as the Point-to-Point Tunneling Protocol (PPTP) and Layer Two Tunneling Protocol with Internet Protocol security (L2TP/IPSec), to connect remote clients and remote
