Routing is what makes the Internet tick, and is one of the most significant networking technologies today. Part I of this book defines Internet routing in general, and discusses a variety of protocols in addition to OSPF. As an introduction to Internet routing, Moy describes both unicast and multicast routing protocols, along with the techniques to monitor and debug routing in a TCP/IP network. This will be very valuable to a large audience.
Part II then delves into the details of one particular routing protocol -- the OSPF protocol. This book provides a detailed description of OSPF (Open Shortest Path First), which was developed by the author. The book explains why OSPF was developed and how it greatly improves network efficiency. It will help engineers to be able to get a better understanding of how to efficiently implement algorithms used in OSPF. It provides a good understanding of how the protocol operates. Each chapter contains exercises to help readers with the subject. This book is unique as it is an up-to-date look at the important topic of routing -- plus it provides the most detail on OSPF available. OSPF is very widely deployed in the Internet, with OSPF implementations offered by virtually all router vendors.
