vpn protocols

The reason why routers can run normally is the result of a lot of different protocols working together, why can the protocols coexist without affecting each other? This is what the following is about, the concepts of routing protocols running. VRF: One of the security initiatives of routing protocols is routing isolat

the data in the connection), and a tunnel (the encapsulated part of the data in the connection ). Creating a tunnel is done through the two tunnel protocols included in Windows 2000, both of which are installed with "Routing and Remote Access. Windows 2000 includes two Protocols:Point-to-Point Tunneling Protocol (PPTP) uses Microsoft point-to-point encryption technology to provide data encryption.L2 Tunneling Protocol (L2TP) uses ipsec to provide dat

With VPN, enterprise employees can connect to the enterprise's VPN Server at any time to connect to the enterprise's internal network. With the "Routing and Remote Access" service of Windows2003, You can implement software-based VPN. VPN (Virtual Private Network) is a virtual private network. A temporary, secure, and

remote clients are the same, each remote client is no longer differentiated separately, thus improving the convenienceAt the same time, it reduces the security of the entire network. In this way, users need to configure only one policy in the VPN gateway device, but each remote customer needs to provide different users during access.The VPN gateway device can centrally manage the legal information of remot

provide L2 VPN based on different data link layers on a unified MPLS network, including ATM, VLAN, Ethernet, and PPP. To put it simply, MPLS l2vpn transparently transmits user layer 2 data on the MPLS network. From the user's point of view, the MPLS network is a L2 switching network, which can be used to establish L2 connections between different nodes. Compared with MPLS l3vpn, MPLS l2vpn has the following advantages: 1) high scalability: MPLS l2vpn

As we all know, because VPN (Virtual Private Network) transmits private information, VPN users are concerned about data security. Currently, VPN uses four technologies to ensure security. These four technologies are Tunneling, Encryption and Decryption, and Key Management) user and device Authentication technology (Authentication ). 1. Tunneling Technology: The t

Xiao Li. The same is true for Mr. Li's reply, which was sent back to Mr. Zhang in his father's name.This communication implementation method depends on the following factors:* Lao Li and Lao Zhang can receive and send emails.* Send the letter to John.* After receiving a letter from his son, Lao Zhang will be able to properly handle (write another envelope) and the re-packaged envelope will be correctly sent out.* At the other end, after receiving the letter, Lao Li will be able to deliver Xiao

The usage of softswitch protocol is described in four special protocols. Next we will give a brief introduction to several main Softswitch protocols, such as H.248/MEGACO, Media Gateway Control Protocol MGCP), and Session Initiation Protocol SIP. Main protocols used by Softswitch The softswitch system involves many Softswitch

Redis Research (13)-security and communication protocols, redis research communication protocols I. Security Salvatore Sanfilippo, author of Redis, once published the Redis declaration, which mentions Redis to be concise and beautiful. Redis does not do much work at the security level.1. trusted environmentThe Redis security design is based on the premise that "Redis runs in a trusted environment". During t

Open source is already widely used in today's software industry, but does open source mean that users can do whatever they want to do with open source code? The answer is no. Open-source sports also have their own game rules and ethics. Failing to comply with these rules will not only damage the healthy development of the open source movement, but also cause reputational and market losses to violators, and more likely fall into legal disputes and compensation. There are many open-source

A Preliminary Study on WCF-17: the equivalence of WCF data protocols, a preliminary study on wcf-17 protocolsData contract equivalenceFeatures If the client successfully sends data of a certain type to the service or the service successfully sends the data to the client, the receiving end does not necessarily have to send data of this type. The only requirement is that the two types of data protocols sho

The routing information protocol, that is, the RIP Protocol. This protocol is one of the earliest in the routing protocol family. It plays a fundamental role in the development of some subsequent protocols. So let's compare several protocols. The Routing Information Protocol (Routing Information Protocol) is an ancient Routing Information Protocol based on the distance vector algorithm. It selects the optim

How to quickly learn about network protocols and network protocolsI. What is the network protocol? Generally speaking, network protocols are a bridge between networks for communication and communication. Only computers with the same network protocol can communicate and communicate information. This is like the various languages used for communication between people. Only when the same language is used CAN c

Network transmission protocol or communication protocol for shortProtocol) refers to the common language for computer communication. Currently, the most popular computer communication is network communication. Therefore, the "Transfer Protocol" generally refers to the transmission protocol for computer communication, such as TCP/IP and NetBEUI. However, the transfer protocol also exists in other computer forms of communication, such as communication between objects in object-oriented programming

OC-Concepts and usage of protocols, oc-concepts of protocols In the previous article, we introduced the class extension in OC: Extend. The protocol in OC is equivalent to the interface (abstract class) in Java, but the name in OC is more vivid, because when we are learning interfaces in Java, it can be seen that the interface is equivalent to a contract (Protocol), marking its implementation class. Of cour

WIN8 Cisco VPN 442 Error solution/Error Code 442 Cisco VPN Clinet with Windows 8 when you start using win8, because of work needs to use Cisco VPN Client, however, in win8, the Cisco VPN Client reports a 442 Error and cannot be used. The following Error message is displayed: Error Code 442 while connect to

protocols are AH and ESP. From the principle, we can see that, in the end, NAT may only work with ESP in tunnel mode. Let's take a look at the work of site-to-site vpn for users in traditional units: 1. In the tunneling mode www.2cto.com, the local-address and des-address must be specified manually on each site, therefore, when establishing a tunnel between the site and the site, it is the source and desti

To sum up, a VPN is a private connection that is established between two machines or two networks by sharing a public network. In fact, VPN technology enables organizations to safely extend network services over the Internet to remote users, branch offices, and cooperative companies. In other words, the VPN turned the internet into a dedicated WAN for impersonati
