TCP/IP Network Basics
TCP/IP Protocols
Sockets For TCP/IP protocol, when a packet is delivered to a specific IP address, it is
passed up to TCP or UDP and then to the appropriate host. This process
forms a funnel through the TCP/IP stack, called a
socket. A socket is
uniquely defined by the IP address, the end-to-end protocol (TCP or UDP),
and the port number.
This figure shows typical socket architecture. When a socket is first created,
it has an associated protocol but not an IP address or port number. A socket
must be
bound to a port number before it can receive messages from a
remote application.
