Client Process

A client process uses an ephemeral port, a random port number ranging from 32768 to 61000 on Linux, and from 49152 to 65535 on Windows, used for temporary connections.

Only one process can use one port number at a time.

Peer-to-Peer processes

peer-to-peer process

A process where the client and the server are both in one process. These are multithreaded, where the server thread listens on a well known port, and each client thread connects to a different server.

Socket Programming

• stream sockets are used for TCP connections

  • Uses a byte-stream abstraction, which provides in-order, reliable delivery.

• datagram sockets are used for UDP connections
