1. UDP: A transport layer protocol for user datagram. Unreliable and connectionless. 2. header (8B in total): source port number (2B), destination port number (2B), UDP length (2B), UDP checksum (2b) Note: (1) for UDP port numbers, the port numbers are used to mark the application process. TCP and UDP can share a port number, which can be distinguished by protocol fields in the IP header. (2) UDP lengt

Differences between get and post in http protocol, and getpost Protocol We are no stranger to the get and post submission methods in the http protocol. Now we analyze the nature and difference of the two submission methods.First, let's talk about the differences between the two of them:Difference between the post and get methods in Form submission 1. get is to g

Linux Kernel protocol stack socket query cache routing mechanism, protocol stack socketIs it faster to query the route table? Or is it faster to query the socket hash table? This is not the root of the problem. The root cause of the problem is how to use the two effectively, so that the two can become partners rather than competitors. What's going on?We know that if a data packet is to arrive locally, it wi

BSD and GPL are two common protocol types in the open source field. The differences between the two are as follows: If you use a BSD-based OpenSource codeIn addition to opening up the sourceCodeIn addition, it can also be issued as a binary form, or even as a commercial software release. (You must also follow the BSD Protocol) If you use open-source code based on the GPL

I. Introduction to the implementation of the stop-and-wait protocol I designed the program to implement the rdt3.0 version of the stop-and-wait protocol, the sender sends packets in the order of 0, 1 alternating, and when the 0 packets begin to be timed, only receive the ACK0 to continue sending 1 packets, if it has timed out without receiving the ack0, This requires retransmission of packet 0; The receiver

Use _seed the to _msgx decrypt to get the plaintext message. Call results return process Returns th

RTCP RTP protocol format Analysis 5: RTCP protocol sending and receiving rules tp: the time when the RTCP package was last sent. Tc: current time. Tn: the time when the next RTCP package will be sent. Pmembers: Number of session members in the most recent calculation of tn. Members: current estimation of session members. Senders: estimate the number of senders in a session. Rtcp_bw: Target RTCP bandwidth.

　　I. Introduction After the program runs, the time protocol (rfc868) is obtained through the network. If it fails to be obtained within five seconds, it will continue to retry after three seconds until it is obtained successfully. After obtaining the time, the program will try to adjust the computer system time. If the adjustment is successful, a message box will pop up: Your computer system time was prooflisted: The time in the information

HTTP protocol and java Protocol After listening to a teacher's course, I felt that I was not familiar enough with HTTP. Therefore, I decided to write this blog post. First, you can refer to this article: http://blog.csdn.net/gueter/article/details/1524447 Part 1: communication process between the browser and the server: Part 2: Introduction to HTTP requests: Part 3: HTTP Response Which book is

Workaround: Add key to Info.plist Let me introduce you to the HTTP and HTTPS protocols in iOS. Recently done a project, began to use the HTTP protocol to achieve client and server-side interaction, and later need to change to HTTPS protocol. Some problems were identified during the modification process, and the solution was as follows: HTTP: NSString *urlstring =[nsstring stringwith

a server error in the "/WCF" application. There is no protocol binding that matches the given address "http://localhost:8001/WCFService.HelloService". Protocol bindings are configured at the site level in IIS or was configurations. This error indicates that the configuration file is not configured correctly. Error: Name= "Wcfservice.helloservice" > Correct: Name= "Wcfservice.helloservice" >

(1) UDP is a connectionless protocol. The source end of data transmission does not establish a connection with the terminal. when it wants to transmit data, it simply crawls data from the application, and throw it to the network as quickly as possible. At the sending end, the speed of UDP data transmission is limited only by the speed at which the application generates data, the ability of the computer, and the transmission bandwidth. at the receiving

1: Request Line The request line is divided into three parts: Request mode: GET, POST Resource path:/servlet/request HTTP protocol version: http/1.1 http/0.9: Only receive one request method is accepted, no version number is specified in the communication, and the request header is not supported. Because the Post method is not supported by this version, the client cannot pass too much information to the server. http/1.0: The first version number

PPP is one of the most basic protocols in the network. PPP is the main content of this article. First, let's take a look at the basic concepts of the PPP protocol. The Point-to-Point Protocol is a data link layer Protocol designed to transmit data packets between equal units. This link provides full duplex operations and transmits data packets in sequence. PPP pr

All WWW documents must comply with this standard. HTTP was originally designed to provide a way to publish and receive HTML pages. 1960 American Ted Nelson conceived a way to process text messages through a computer called hypertext (hypertext), whic
