If you've ever run a forced-hot air heating system, it's not too hard to understand by analogy the basics of Network Systems. Of course, your heating system needs a humidifier attached to it, but the humidifier in a state-of-the-art HVAC system only operates when the central processor determines it's necessary, given information needed to calculate indoor relative humidity from the indoor thermostat, humidistat, and outdoor thermometer.
Network systems are network-attached, computational systems that receive, process and transmit data packets. The advances in high speed transmission technologies require high-speed link attachments that are able not only to receive and transmit data at high speed but subsystems that store and process packets as well, at speeds that are equivalent to the link speeds.
The architecture of network systems, i.e. adapters, switches, bridges, routers, etc., constitutes a new technical area that requires skills in computer architecture, design methodologies, algorithm design and networking. As an emerging field, the architecture of network systems enables a systematic approach for the definition and development of network systems, analogous to that of computing systems.
This book addresses the need for a systematic treatment of the technical aspects of network systems architecture.
First book to provide comprehensive coverage of the technical aspects of Network Systems...bridges the gap between network operation and VLSI, providing professionals with structured approach to solving problems currently handled on an ad-hoc basis;
A handy, "how-to" for anybody entering the field of Network Systems Architecture and a valuable reference for all practitioners...provides comprehensive coverage of practice and methodologies from two renowned authors, obviating need to locate and read numerous, research-level publications;
Develops a systematic approach to Network Architectures, based on the OSI reference model...approach based on well-understood model, with widely accepted performance goals;
Covers all necessary basics of Network Systems Architecture, followed by leading-edge topics, e.g., Quality of Service and Security for mobile, real-time P2P services (VoIP, e-commerce, etc.) and Low-Power Requirements for Mobile Systems (mobile phones, PDAs, etc.)...appeals to the widest possible audience;
