Socket是指一个上面有很多“洞”的东西,比如说,计算机主机板上CPU的插座,我们称其为Socket 478或Socket 939等,而Socket上面这些洞在传输层中则称为Port,在OS的网络系统中会有两个Socket,分别为TCPSocket及UDP Socket,Socket上各有65536个洞,我们把它称为Port 0、Port 1、Port 2 …… Port 65 535。 我们以图...

每个TCP报文头部都包含源端口号(source port)和目的端口号(destination port),用于标识和区分源端设备和目的端设备的应用进程。 在TCP/IP协议栈中,源端口号和目的端口号分别与源IP地址和目的IP地址组成套接字(socket),唯一的确定一条TCP连接。 相对于TCP报文,UDP报文只有少量的字段: 源端口号、目的端口号、长度、...
简单说，ip地址是用来找机器的，端口是用来在找到机器以后作更进一步的进程、模块路由的。如果没有端口这...

Why Error "Add rule to chip failed" or Is Error "Adding rule failed" Is Frequently Reported When an ACL Rule Contains a TCP or UDP Port Range? The number of applied rules that contain "range" has reached or exceeded the maximum. The S series cards support 16 TCP or UDP port ranges ...
Port of TCP/UDP ftp base on tcp, using port 20 and 21 tftp base one udp, using port 69 http base on tcp, using port80 telnet base on tcp, using port 23 SMTP base on tcp, using port 25
Ports are a transport layer (layer 4) concept. Only a transport protocol such as theTransmission Control Protocol (TCP)orUser Datagram Protocol (UDP)can indicate which port a packet should go to. TCP and UDP headers have a section for indicating port numbers.Network layerprotocols — for insta...
TCP and UDP Port Assignments 项目 2010/03/04 Transport Control Protocol (TCP), User Datagram Protocol (UDP) ports, and Protocol Numbers are important to TCP/IP networking, intranets, and the Internet. Ports and protocol numbers provide access to a host computer. However, they also create a...
