Research and development on optical wavelength-division multiplexing (WDM) networks have matured considerably. While optics and electronics should be used appropriately for transmission and switching hardware, note that "intelligence" in any network comes from "software," for network control, management, signaling, traffic engineering, network planning, etc.The role of software in creating powerful network architectures for optical WDM networks is emphasized.Optical WDM Networks is a textbook for graduate level courses. Its focus is on the networking aspects of optical networking, but it also includes coverage of physical layers in optical networks. The author introduces WDM and its enabling technologies and discusses WDM local, access, metro, and long-haul network architectures. Each chapter is self-contained, has problems at the end of each chapter, and the material is organized for self study as well as classroom use. The material is the most recent and timely in capturing the state-of-the-art in the fast-moving field of optical WDM networking. Next-generation High-speed Internet Backbone Networks Will Be Required To Support A Broad Range Of Emerging Applications Which May Not Only Require Significant Bandwidth, But May Also Have Strict Quality Of Service (qos) Requirements. Furthermore, The Traffic From Such Applications Are Expected To Be Highly Bursty In Nature. For Such Traffic, The Allocation Of Static Fixed-bandwidth Circuits May Lead To The Over-provisioning Of Bandwidth Resources In Order To Meet Qos Requirements. Optical Burst Switching (obs) Is A Promising New Technique Which Attempts To Address The Problem Of Efficiently Allocating Resources For Bursty Traffic. In Obs, Incoming Data Is Assembled Into Bursts At The Edges Of The Network, And When The Burst Is Ready To Be Sent, Resources In The Network Are Reserved Only For The Duration Of The Burst. The Reservation Of Resources Is Typically Made By An Out-of-band One-way Control Message Which Precedes The Burst By Some Offset Time. By Reserving Resources Only For The Duration Of The Burst, A Greater Degree Of Utilization May Be Achieved In The Network. This Book Provides An Overview Of Optical Burst Switching. Design And Research Issues Involved In The Development Of Obs Networks Are Discussed, And Approaches To Providing Qos In Obs Networks Are Presented. Topics Include: - Optical Burst Switching Node And Network Architectures - Burst Assembly - Signaling Protocols - Contention Resolution - Burst Scheduling - Quality Of Service In Obs Networks Technology And Architecture -- Burst Assembly -- Signaling -- Contention Resolution -- Channel Scheduling -- Quality Of Service -- Other Topics.
