The difference between the UDP protocol and the TCP protocol is no longer analyzed, mainly to analyze how these two protocols are used in Java communication programming.First introduces TCP, which provides good support for the Tcp,java language. To establish TCP communication, you need to build the server first andTo the server's IP and port number.Socket class under the TCP protocol:The Java.net.Socket cla

Commands and responses to the SMTP protocol
From the previous communication model, you can see that the SMTP protocol's session between sending SMTP and receiving SMTP is done by sending SMTP commands and receiving an answer to SMTP feedback. After the communication link is established, Send SMTP send mail command message sender, if receive SMTP at this time can receive mail then make OK answer, and then send SMTP continue to Issue RCPT command to co
The Wgscd-picked Rtp/rtcp (real-time transport protocol/real-time Transport Control Protocol) is based on UDP-derived protocols and adds control over real-time transmission. Commonly used for online transmission of real-time video data, such as remote video surveillance, video-on-demand. There is a book called "Multimedia Network Transmission Protocol" on the s
RIP and IGRP are commonly used router configuration protocols. What problems should we pay attention to when configuring RIP and IGRP? What should we do? The following configuration steps provide detailed answers.
RIP Protocol
RIP (Routing information Protocol) is an Internal Gateway Protocol (IGP) that is widely used earlier and is suitable for small-sized sim
The TCP protocol is a unique identifier (IP address, protocol, port) that interacts with other processes using the network communication fee.TCP and UDP are the most different place, TCP provides a reliable data transmission service, TCP is connection-oriented, that is, the use of TCP communication between the two host first to go through a "call" process, wait until the end of the communication is ready to

SSCOP Service specific Connection oriented Protocol business-specific connection-oriented protocolThe function of SSCOP is to provide service to its upper SSCF module, to establish and release signaling connection for upper layer signaling user, and to provide a confirmed and non-verifiable message data transmission on the connection to reliably exchange signaling messages.It utilizes the non-reliable transmission process provided by the SAAL-CP layer
ICMP Internet Control Message Protocolis generally considered an integral part of the IP layer and is generally used by the IP layer or higher (TCP, UDP).The ICMP message is transmitted inside the IP datagram.The format of the ICMP message is as follows:The first 4 bytes of the message are the same: 8bit type, 8bit code, 16bit test and.The ICMP packets have different message types, and the different types are determined by the 8bit type and the 8bit code together. There may be more than one code

This is an http-based resumable data transfer protocol, mainly using different httpmethods and related custom headers to implement the resumable data transfer function.Specific methods and headers:1.

AJP13 is a directional packet protocol. For performance reasons, use binary format to transfer readability text. The Web server is connected through a TCP connection and a servlet container. To reduce the cost of the process to generate a socket, the Web server and the servlet container try to maintain a persistent TCP connection and reuse a connection for multiple request/reply loops. Once the connection is assigned to a specific request, it is not a
