Routing in the Internet

This comprehensive guide to all the latest advances in Internet routing protocols is written in a very user friendly style. Taking an applied approach, the author examines the organization of routing, the structure that glues together the worldwide Internet. Routing in the Internet: introduces the general principles of the Internet architecture and presents IP - the Internet Protocol; describes routing with organizations' networks. It presents RIP, the most widely used "interior gateway protocol" in today's Internet, and makes OSPF easy to understand. It also presents IS-IS, IGRP, and EIGRP; explains the set of routing protocols required for interconnections between organizations' networks and their providers. It shows the progress of the technology from EGP, the first "external gateway protocol", towards BGP, the new "border gateway protocol", and the recently developed CIDR - "Classless Inter Domain Routing". A separate chapter presents the requirements of "policy-based routing" and details the recent advances in routing technology including multicast transmission, mobile hosts, and the support of real time applications. These technologies will be used by the new generation of the Internet Protocol, IPv6, that will connect thousands of billions of hosts in the 21st Century.
