The Transmission Control Protocol, or TCP, is one of the foundational technologies of packet switched networks. TCP not only provides windowed flow control, it also manages the retransmission of data when errors are detected, and sockets for addressing individual applications on a host. Douglas Comer was involved in the early development of TCP/IP. post wikipedia
Prior to Comer’s books, which have now been translated into over 16 languages and are still widely used in academia and by networking professionals around the world, the only source of information about the Internet’s design and protocols was limited to standards documents, which only outlined individual protocols. Comer’s books went beyond this to explain, critically, how protocols work together. post
