TCPvsUDP explanation and DifferenceThis article mainly collects the concepts of UDP and TCP and the connection establishment process: UDP: User Datagram Protocol Broadcast and multicast are only applied to u d p. They are very important for

Differences between the three properties for obtaining the user IP address (HTTP_X_FORWARDED_FOR, HTTP_VIA, REMOTE_ADDR) I. No proxy server is used: REMOTE_ADDR = Your IP HTTP_VIA = no value or no display of HTTP_X_FORWARDED_FOR = no value or no

You must know the Special IP addresses in the IP address. You must know one type of IP addresses. These IP addresses cannot be used in public network 1, local address 127.0.0.X send-back interface 2, Class A address 10. x. x. class A address for X 3,

Network Protocol designers should not design a single, huge protocol to provide complete details for all forms of communication, but should divide communication problems into multiple small problems, then a separate protocol is designed for each

TCP-UDP Transport Layer ProtocolTCP and UDP are the transport layer protocols of the TCP/IP protocol family: 1. TCP: connection-oriented: the process of creating a connection, communication between the two parties, and closing the connection. The

Modify the DNS wizard of the new network domain name if you want to try or use the DNS-related resolution service provided by us, please first register your domain name online on the "register for trial" page of the website, after registration, log

Introduction to TCP/IP architecture the TCP/IP protocol set divides the entire network into four layers, including the network interface layer, Internet layer, transport layer and application layer. 1. network Interfaces and Communication Subnet

Firewall Intranet users access internal servers through public network domain names or public IP addresses I. Networking requirements: www.2cto.com allows internal users to access internal servers through the domain names provided by the carrier

Expression: the basic expression of an IPv6 address is X: X. Each number contains 4 hexadecimal data and the tool is 128 bits. The starting 0 does not need to be expressed. The above is the most basic expression method, and there are two more clear

Before introducing wireless network interfaces, I would like to summarize some of the currently popular Wireless Access Technologies in China and internationally (technical details are not described ), because different wireless access technologies

Cisco ACL has two types: Standard ACL and extended ACL. The standard ACL of www.2cto.com allows or rejects traffic based on the source IP address. The destination address and port contained in the data package are irrelevant. The example on the

What are the functions of the ping command? The ping Command www.2cto.com is used to check the smoothness of the network. ping is an ip testing software that comes with window. It can test whether the local machine is connected to a vro. For example,

Abstract: This article briefly introduces TCP connection-oriented theory knowledge, describes the meaning of each field of TCP packets in detail, and captures data from Wireshark.Select a TCP connection in the group to establish the relevant packet

The Extension Header of IPv6 is an optional Header that may follow the basic IPv6 Header. An IPv6 packet can contain one or more extension headers. Of course, there can be no extension headers. These extension headers can have different lengths. The

Differences and connections between TCP and UDP 1. connection-oriented TCP www.2cto.com TCP (Transmission Control Protocol) is a connection-based Protocol. That is to say, before sending and receiving data, you must establish a reliable connection

The TCP/IP knowledge that programmers need to know may not be available for most project development projects. However, as a technical engineer, the basic TCP/IP knowledge is essential, it is also helpful for future development in this area.

Exploring TCP details: establishing TCP connectionsCurrently, most C/S architecture systems use the TCP protocol for communication between components, mainly because the TCP protocol is a stable and reliable transmission protocol, however, most

By default, the priority of both the wired and wireless network interfaces is high. If you want to change the priority to the wireless network, enter the connection attribute of the wired network interface, select the TCP/IP attribute, and click

Computers rely on electrical pulses to turn 0.1 into a recognizable mechanism.Encoding Rules, communication between two computers is transmitted between high and low levelsBefore the encoding rule is passed, the recipient has a decoding rule,The
