A process associates its input or output channels via an internet socket , which is a type of file descriptor , associated with a transport protocol , a network address such as an IP address , and a port number.
A server may create several concurrently established TCP sockets with the same local port number and local IP address, each mapped to its own server-child process, serving its own client process. They are treated as different sockets by the operating system since the remote socket address (the client IP address or port number) is different; i.e ...
PCP allows equipment and applications to create explicit mappings between an external IP address, protocol and port, and an internal IP address, protocol and port. With such explicit mappings in place, inbound communication can reach the hosts behind a NAT or firewall, which either expands their server roles beyond boundaries of local networks ...
