Networking technologies and practices are constantly evolving, and this carefully revised edition equips students with the understanding needed to keep pace. Authors Peterson and Davie emphasize a systems-oriented approach, focusing on the "why" of network design rather than just specifications. This edition covers Quality of Service issues, mobile and wireless networks, VPNs, and more, with over 100 new exercises to help consolidate knowledge. The authors, with over 30 years of experience in networking, provide unparalleled instruction on the principles and practical implementation of computer networks. The second edition includes cutting-edge topics such as security techniques (PGP, IPSEC, secure sockets, and firewalls), application layer protocols (SMTP, HTTP, SNMP, DNS, and RTP), and new material on wireless technology (spread spectrum techniques and 802.11).
