例如,对于每个TCP/IP实现来说,FTP服务器的TCP端口号都是21,每个Telnet服务器的TCP端口号都是23,每个TFTP(简单文件传送协议)服务器的UDP端口号都是69。任何TCP/IP实现所提供的服务都用知名的1～1023之间的端口号。这些知名端口号由Internet号分配机构(InternetAssignedNumbersAuthority,IANA)来管理。

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 security hazard by allowing uninvited access. Ther...
TCP and UDP headers have a section for indicating port numbers. Network layer protocols — for instance, the Internet Protocol (IP)— are unaware of what port is in use in a given network connection. In a standard IP header, there is no place to indicate which port the data packet ...
SNMP Port Numbers SNMP packets are common UDP packets. SNMP defines two default port numbers: Port 161: This port number is used when the NMS sends Get, GetNext, GetBulk, and Set requests and the SNMP agent responds to these requests. This port number is configurable. Ensure that the port...
