Currently, network security and network address translation are widely used. For any of these technologies, it is very good. Many people are thinking about how to share two good technologies but make them safe. Network Security IPsec (IP Security)

Python provides two basic socket modules. The first one is the Socket, which provides the standard BSD Sockets API. The second is Socketserver, which provides a server-centric class that simplifies the development of Web servers. Here is the socket

1, the establishment of TCP connection method The client typically takes two steps to establish a TCP connection, and the server process takes four steps, as shown in the following comparison. Steps TCP Client TCP Server

It is very helpful to know some knowledge about the route selection protocol. So I have studied the basic knowledge of VPN in the routing protocol and will share it with you here. I hope it will be useful to you. VPN is a Cisco dedicated protocol

When talking about network security, I want to learn more or less about it. The so-called network security means that the hardware, software, and data of the network system are protected, measures to ensure continuous and reliable operation of the

With the rapid development of computer network technology, network security issues have become increasingly prominent in the face of various users ...... With the rapid development of computer network technology, network security issues have become

OSPF Protocol principle 1. ospf (Open Shortest Path First) is an Internal Gateway Protocol (IGP) used for decision-making routing in a single autonomous system (. Ospf runs directly on the IP protocol and uses protocol number 89. ospf is a

At present, many devices are often converted through routers and firewalls. However, the price of the devices that want to meet the OC192 line rate is usually very high, and the investment in comprehensive monitoring of the entire network is very

The checksum Algorithm for IPv4, TCP, and UDP checksum calculation of the packet header is a 16-bit accumulated and backward code. The same verification algorithm is also used for TCP and UDP data headers, however, the data involved in the

The status and closing method of TCP connections and their impact on the Server and Client 1. The status of TCP connections first describes the status during the establishment and closure of TCP connections. The TCP connection process is a state

Sorrow needs to endure, happiness needs to be sharedI couldn't stand the performance of the Linux stack multiple times perf, but it was so powerful that I couldn't give it up, I wanted to implement a fast flow meter myself, but I had to abandon many

The process of establishing a TCP connection for a server is divided into 4 steps:1. Set up the socket object: here, as with the client, remains:S=socket.socket (Socket.af_inet,socket. SOCK_STREAM)2. Setting and getting socket optionsPython defines

Hardware redundancy · The monitoring engine is an important component of modular SW. Once a monitoring engine encounters a problem, it cannot forward communication streams. There are two monitoring engines for redundancy in some high-end SW4500/550

This is a creation in Article, where the information may have evolved or changed. Todo:golang UDP connection Simple test with caution deadline UDP is the abbreviation of User Datagram protocol, the Chinese name is a Subscriber datagram protocol, is

This is a creation in Article, where the information may have evolved or changed. NET package provides a portable interface for network I/O, including TCP/IP,UDP, domain name resolution, and UNIX sockets. Although the net package provides a lot of

The server is very similar to the client program. The client program is learned in the previous section. This section describes how to use socket to establish TCP and UDP servers. 1. TCP connection establishment method Generally, two steps are

Network programming, and obtain protocol data by protocol name-Linux general technology-Linux technology and application information. The following is a detailed description. # Include # Include Int main () { Struct protent * pro;

The principle of layer-3 switching has always been the most difficult for many readers to understand. In daily reader exchanges, we often see readers raise this issue, especially the differences and connections between layer-3 switching and routing

Currently, network security and network address translation are widely used. For any of these technologies, it is very good. Many people are thinking about how to share two good technologies but make them safe. Network Security (IPsec) and Network
