For junior to graduate-level courses in Computer Networks, Data Networks, Network Protocols, and Internetworking.

This best-selling, conceptual introduction to TCP/IP internetworking protocols interweaves a clear discussion of fundamentals with the latest technologies. Leading author Doug Comer covers layering and shows how all protocols in the TCP/IP suite fit into the five-layer model. With a new focus on CIDR addressing, this revision addresses MPLS and IP switching technology, traffic scheduling, VOIP, Explicit Congestion Notification (ECN), and Selective ACKnowledgement (SACK).
