IP Virtual Private network is a very complex technology, involving all aspects, the most critical of which is the tunnel technology. Simply put, the virtual private network is actually the data encapsulation of the enterprise network in the tunnel for transmission. Because the tunneling protocol is relatively complex, the virtual private network technology is complicated. The most typical of tunneling protocols are IPSec, L2TP, GRE, PPTP, L2F, and so on. Where GRE, IPSec belongs to the third-tier tunneling protocol, L2TP, PPTP and L2F belong to the second-tier tunneling protocol. The essential difference between the second and third-tier tunnels is that ...

To adapt to the needs of information and mobile office, many enterprises have deployed VPN servers. The VPN (virtual private receptacle), which is built on the Windows Server 2003-based Routing and Remote Access service, is a secure and convenient remote access solution, and is now the preferred choice for most small and midsize enterprises. 　　Then how to secure the VPN is a problem for the enterprise CIO to face. VPN solution is to virtual ...

Resource sharing and telecommuting are one of the most important contributions of network to modern society. In colleges and universities with scientific research education as their duty, the important significance of various academic documents, teaching materials and frontier technology sharing is particularly prominent. The network environment of colleges and universities is a more special environment, because of the large capacity of intranet, it often compose the campus network with more complicated structure.　　The shared resources are often concentrated in the library of the University electronic database, as well as the use of Off-campus electronic database, the formation of the campus resource sharing pattern. Campus Network barrier as the vanguard of domestic Water Conservancy research, university information Construction ...

Recently, the FBI has proven to people the fact that it is easy to analyze attacks on wired equivalent encryption to gain access to wireless networks that use this security protocol. According to the announcement, Jonathan Yarden is considering a test of the role of security in the wireless network, and based on the results of this test, he will make some suggestions on how to protect the safety of wireless networks. Years ago, in a computer exhibition with a very prosperous network concept unit, I was paralyzed in one now ...

As enterprise management becomes more and more dependent on the efficiency of the network and the applications running on the network, Managing enterprise network bandwidth becomes increasingly important. Wilton launched the Flow management products are committed to protect the enterprise's key business bandwidth resources, to limit the misuse of the bandwidth of the business, to avoid network congestion, for enterprises to create transparent visibility of the network application environment. One of the key to this type of equipment is the analysis of existing customer traffic, which is based on the analysis of the Application Layer network protocol. Based on the DPI (depth packet detection)/DFI (deep flow detection) technology, we have a wide range of current network ...
