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). Includes coverage of Voice and Video Over IP (RTP), IP coverage, a discussion of routing architectures, examination of Internet application services such as domain name system (DNS), electronic mail (SMTP, MIME), file transfer and access (FTP, TFTP, NFS), remote login (TELNET, rlogin), and network management (SNMP, MIB, ANS.I), a description of mobile IP, and private network interconnections such as NAT and VPN. The new edition includes updates to every chapter, updated examples, a new chapter on MPLS and IP switching technology and an expanded TCP description that featuers Explicit Congestion Notification (ECN) and Selective ACKnowledgement (SACK). For network and web designers, implementers, and administrators, and for anyone interested in how the Internet works.
