Network Processors

Architecture, Programming, and Implementation

By
  • Ran Giladi, Associate Professor, Ben-Gurion University, Israel.

Network processors are the basic building blocks of today's high-speed, high-demand, quality-oriented communication networks. Designing and implementing network processors requires a new programming paradigm and an in-depth understanding of network processing requirements. This book leads the reader through the requirements and the underlying theory of networks, network processing, and network processors. It covers implementation of network processors and intergrates EZchip Microcode Development Environment so that you can gain hands-on experience in writing high-speed networking applications. By the end of the book, the reader will be able to write and test applications on a simulated network processor.

Audience
PRIMARY- Industry practitioners; systems engineers, architects, product managers and software engineers from communication systems vendors, telecommunications carriers and service providers; application developers and R&D level engineers that need high-speed networking solutions, for example in defense and intelligence communities.

SECONDARY- Text for undergraduate and graduate level courses on Network Processors and on high-speed networking; reference for researchers.
