Welcome to the world of routing!

Routing is the technology that enables worldwide Internet communication. Many people involved with networking technologies or companies need to know how routing works. But learning about routing tends to involve a complex web of terms and acronyms-a language that can be difficult and unfamiliar.

No routing experience needed!

Routing First-Step explains the basics of Internet routing in language all of us can understand. This book takes you on a guided tour of routing, starting with systems you are familiar with: the postal system, the telephone system, and the interstate highway system. From there, you'll learn routing simply and easily. Whether you are looking to take your first step into a career in networking or are interested only in gaining knowledge of the technology, this book is for you!
