internet protocol tcp ip properties

This article turns from cnblogs:http://www.cnblogs.com/xhwy/archive/2012/03/03/2378293.htmlI. Overview1.1 TCP HTTP UDP:is the communication protocol, that is, the rules of communication, only the two parties in accordance with this rule "speak", the other party can understand or serve.The relationship between TCP HTTP UDP three:TCP/

Network protocol HTTP, TCP/IP, SocketThe network seven layer is from the bottom up to the physical layer, the data link layer, the network layer, the transport layer, the conversation layer, the presentation layer and the application layer respectively.The physical layer, the data link layer and the network layer are often called media layers, which are the objec

media in the network is different, it is better than a long pipe, which is composed of different water pipes of different thickness (different MTU). The maximum water volume of the pipe is determined by the finest water pipe in the middle. For upper-layer protocols at the network layer (here, the TCP/IP protocol family is used as an example), they do not care a

is busy but the TCP status is time_wait, it can be reused. Port. If the port is busy while the TCP status is in another status, an error message is still returned when the port is reused, Specify "The address is in use ". If you want to restart the service immediately after the service program is stopped, and the new socket is still When the same port is used, the so_reuseaddr option is very useful. You mu

Haha! In September 18, I will take the National Computer Level 3 examination. I apply for network technology. Some students say this is simple, and now I have a lot of contact with my computer, it is best to know something about the TCP/IP protocol.I read some books today! Something about the TCP/IP

1. the TCP (Transmission Control Protocol)/IP (Internet Protocol) protocol family is a network communication model and an entire network transmission protocol family. It is the basic co

TCP/IP protocol cluster BASICS (1) network interface layer: the basic layer of the model, responsible for sending and receiving data frames (frame is an independent network information transmission unit ). The Network Interface Layer places frame data on the network or retrieves frames from the network. (2) network layer: encapsulate data into

For the Internet, various protocols are used to regulate its usage, so that this large and complex network can work in an orderly manner. In this protocol structure, the tcp ip protocol family is the foundation. What protocols are included in this structure? In order to allo

follows:Telnet: provides remote login terminal simulation) service, as if the older BBS is used for this login.FTP: provides application-level file transfer services, which are simple and clear: Remote File Access and other services;SMTP: The E-mail protocol used every day.TFTP: provides a small and simple File Transfer Service. In fact, from a certain perspective, it is a replacement for FTP when the file is very small and only needs to be transferr

. Pass the PRC_XXXX error code to the control input function of the protocol.The 3.internet PCB protocol (TCP and UDP) maps a prc_xxx error code to a UNIX errno value, which is returned to the process.8.udp_usrreq functionMany operations call the Protocol's user request function, and one of the five write functions is invoked on a UDP socket to call UDP on reques

You may have heard of the TCP/IP protocol. Do you know what TCP is and what Ip is? In this chapter, we will learn about the most widely used protocol on the network. 7.1 network transmission layeringIf you have passed the compute

used 6 colon-delimited hexadecimal integers, such as: 00:0c:29:d2:58:6b3, port number (port): The port number is an application for the transport layer of an identity, the transport layer through the port number to distinguish between different applications, TCP and UDP with 16bit port number to identify the application4. Socket (socket): An address composed of an IP address and a port number, such as: 111
