desired VPN solution, managing it on behalf of the enterprise, and using the security gateway (Firewall, router, etc) on the user side. 6. division by VPN business level model This is based on the layer at which the VPN service provided by the ISP works (not based on the layer where the tunnel protocol works ). (1) dial-up VPN service (VPDN): This is the VPDN in the first partitioning method (in fact, it is divided by access method, because it is difficult to determine which layer the VPDN belo

I want to improve my programming technology. A developer who is a PHP programmer is free to pick up outsourcing projects (or go to outsourcing companies) on his own ), I still want to go to Internet companies to learn and constantly improve their programming technologies. Now I want to improve my programming technology, a developer who is free to be a PHP programmer. If you want to connect to an outsourc

　　Each system will have his life cycle, from life to death, through the three stages of adolescence, middle age and old age. 　　The management of complexity runs through the whole life cycle of the system, just like the natural choice of evolution, constantly optimizes the system and keeps the system alive. The initial stage of the system is to complete the construction of 0 to 1 to verify the business model or to do the smallest demo product. This is the time and cost of priority, and that is fa

-service routers can provide comprehensive VPN solutions, including L3MPLSVPN, VLL, VPLS, and GRE. In Tang xiongyan's view, the operator needs to formulate detailed user policies and billing policies. "The operator sends detailed billing policies to the policy server based on the behavior of each user and sends instructions to the Service Router, the Service Router technology makes corresponding behavior ad

technology does Google use? PageRank is the webpage level.Google has a founder named Larry Page. It is said that he applied for the PageRank patent, so he got Page Rank based on his name. There is also a very successful search engine company in China, called Baidu (http://www.baidu.com ). Baidu founder Li Yanhong said that as early as 1996, he applied for a patent named hyperchain analysis. PageRank's principle is the same as that of hyperchain a

the expansion of L2 networks not only close to the boundaries of the data center, you also need to consider extending the data center area to the local backup center and remote disaster recovery center. Generally, the connection between multiple data centers is connected through a route, which is a layer-3 network. To connect two L2 Networks connected through a three-tier network, you must implement "L2 over L3 ". There are also many L2oL3 technologies, such as the traditional

ensure high capacity, high performance and high speed IP bearer network development requirements. With the development of the latest route exchange technology, the traditional test content such as route table capacity test, exchange and forwarding capability test, and even oscillating test cannot meet the test requirements of high capacity, high performance, and function-rich route exchange technology. For

requirements of high capacity, high performance, and rich functional routing and exchange equipment. For example: (1) The combination of OSPF and LDP promotes the development of VPLS technology; (2) The integration of ISIS + RSVP + BGP and other protocols promotes the rapid application of L3VPN technology; (3) The combination of OSPF + LDP + PIM + BGP promotes t

I'm doing it myself, but I've been working on software development for many years, and when I look back on myself, I feel particularly interested in learning Java/dot. NET technology friends say something, I hope you can learn from our experience, how much inspiration (perhaps I say bad, you do not agree with me, but for the sake of my sincerity do not throw bricks AH). One. In China you must not because of learning

layer traffic must be used, that is, the stateful 4 ~ Layer-7 traffic. Separate 4 ~ Layer-7 Traffic testing tools are available on the market, including IXIA IxLoad. One of these tools is to directly connect to the sending and receiving ports of the devices under test, there is no complex and real route table. In order to fully verify the performance of the routing device with the deep packet detection function, the route table and 4 ~ Layer-7 stateful traffic integration testing.The latest dev

This article puts forward the intelligent firewall, this kind of firewall is smarter and smarter, overcomes the traditional firewall's "one tube to die, one puts on the chaos" condition, the revision above firewall's important assumption is "refuses to guarantee the security, releases also must guarantee the security". The new smart firewall changes the concept of "exit" to the concept of "gateway", and all packets passing through the "gateway" must be inspected by the firewall. In contrast to t

China's router technology development is very rapid, at the same time the market demand is also very high, maybe a lot of people do not understand the technology of the proliferation of routers, there is no relationship, read this article you certainly have a lot of harvest, I hope this article can teach you more things. One of the important ways of GFW is the blocking of IP at the network layer. In fact, G

Traditional firewalls are usually based on access control List (ACL) packet filtering, located in the internal private network entrance, so also known as the "border firewall." In addition to the access control features, most firewall manufacturers now integrate other security technologies, such as NAT and VPN, virus protection, on their devices. I. Overview of the development of firewall technology Traditional firewalls are usually based on access

This article is about the current implementation of the shadow in the game, their advantages and disadvantages as well as the application of the occasion. Generally speaking, there are three kinds of shadow techniques applied in the game, projective shadow, shadow Map and Shadow map. We'll introduce them

There are many ways to access the broadband network. At the same time, these methods also use different access technologies. Each new technology can solve the problem that the old technology cannot implement, here we will introduce the features and principles of these technologies. Last step Since June, China Telecom has opened a VPN service for major customers on the newly created CN2, marking the maturit
