• A transport-layer protocol in the TCP suite needs both the IP address and the port number, at each end, to make a connection. The combination of an IP address and a port number is called a socket address.
• The client socket address defines the client process uniquely just as the server socket address defines the server process uniquely as shown in Figure.

• To use the services of transport layer in the Internet, we need a pair of socket addresses: the client socket address and the server socket address.
• These four pieces of information are part of the network-layer packet header and the transport-layer packet header. The first header contains the IP addresses; the second header contains the port numbers.

1. Process to process delivery (transport layer communication) needs two identifiers, one is IP address and the other is port number at each end to make a connection.
2. Socket address is the combinations of IP address and port number as shown in the figure.

1. The client socket address defines the client process uniquely whereas the server socket address defines the server process uniquely.
2. A transport layer protocol requires the client socket address as well as the server socket address. These two addresses contain four pieces.
3. These four pieces go into the IP header and the transport layer protocol header.
4. The IP header contains the IP addresses while the UDP and TCP headers contain the port numbers.
