The detailed analysis of data packet in TCP/IP protocol suite is given out. On the basis of it, a layered protocol analysis module is designed and realized in this paper.

The networks which emerged from this research became the basis for what we know as the Internet, and the protocols developed during this time became known as the TCP/IP Protocol Suite.

The result was a suite of internetworking protocols known as TCP/IP (after the first two protocols defined by the standard, Transmission Control Protocol and Internet Protocol).
