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

IP classification and analysis of Special IP addresses basic IP addresses are 32-bit binary numbers divided into eight-bit units (referred to as eight-bit groups. You can understand both binary and decimal. To make it easier for people to use it,

The advantages and disadvantages of RIP and OSPF are compared. ospf and rip are compared: the rip Protocol is the distance vector routing selection protocol, and the measurement standard (metric) of the selected route is the number of hops, 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

A Brief Analysis of the concept and authentication method of PPP (Point-to-Point Protocol) is a link layer Protocol designed for the transmission of data packets between equivalent units. This link provides full duplex operations and transmits data

TCP connection establishment/removalHow to Establish a TCP connection in Figure 1TCP Header Format, the SYN flag is used only when a TCP connection is established. The TCP connection establishment process is called a "three-way handshake" connection,

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

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

The performance limit of OpenVPN is unsatisfactory because data packets are bypassed in the protocol stack and OpenVPN applications ", each door has its own Width limit. Even if the width of the door is not taken into account, the inbound and

I. Experiment principle vro redundancy protocol (VRRP) is a selection protocol that dynamically allocates the responsibility of a vro to one of the VRRP routers on the LAN. The VRRP router that controls the IP address of a vro is called the primary

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

Packet communication between different network segments host A communicates with host C, A Ping C, figure: A-switch-router M-router N-switch-C, AC different subnets (1) if two machines are not in the same subnet, A must communicate with Objective C.

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.

Example of snoop packet capture parameters: snoop-d hme1-ta-x 54 192.168.30.150 and port 23520 and tcp Parameters: www.2cto.com [-a] # Listen to packets on audio [-d device] # settable to le ?, Ie ?, Bf ?, Tr? [-S snaplen] # Truncate packets [-c

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

TCP streams understand that TCP is a stream protocol. Unlike UDP, when sendto sends a message, the other end will inevitably receive the complete message or no message. When a message is sent using TCP send, the other end may only receive part of

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
