Wavelength division multiplexing (WDM), long-distance optical fiber links and high-capacity all-optical circuit switches are now being worked in the Internet core to process such a large traffic, thus making the demand for novel high-performance packet switching technologies (IP routers, ATM switches, and Ethernet Switches) which feed the optical core. Over the past ten years, tremendous technological advances have occurred in order to achieve that goal. High Performance Packet Switching Architecture is the first book to cover advances in single-volume comprehensive survey.
