Introduction

Within Internetworking, there are numerous career fields, such as network security, IP telephony, and Storage Area Networking (SAN). Content networking is growing so much that it has become a discipline of its own. In the past, most organizations have given the content networking responsibility to the IT operations or network security staff, but these days the field has become so large and complex that organizations often require dedicated content networking professionals to design and operate their content networks.

The purpose of this book is to introduce content networking as an individual field of study, and explain how numerous application and networking concepts are married to make the discipline a whole.
