Introduction

The introductory lesson, presents a brief overview of networking, and the scope and goal of network routing. It also presents architectural aspects of communication networks that are useful in network routing. All of these components have a history and a set of issues to address.

The state of network routing today is the result of theoretical progress, technological advances, and operational experience. It is also impacted by economic and policy issues. The rest of the book explores each aspect of network routing, with a nod toward the historical part, due respect for the scalability-performance tradeoff, and lessons learned from operational experience.

It also gives a brief explanation about routing architectures, service architecture, protocol architecture and also different technologies available in the routing.
