Optical Burst Switching (OBS) has been proposed as a promising switching
architecture to support huge bandwidth requirements in optical backbone
networks using Wavelength Multiplexing Division (WDM) technology. Due to
its special features which combine the merits of optical circuit
switching and packet switching, it can support high-speed transmission
with fine bandwidth granularity using off-the-shelf technologies. OBS
has attracted a lot of attention from researchers in the optical
networking community.
This book provides a comprehensive discussion on the quality of service
(QoS) issue in OBS networks. It examines the basic mechanisms to improve
overall QoS in OBS networks as well as discusses the relative QoS
differentiation among multiple service classes in OBS networks. Coverage
also details absolute QoS provisioning in OBS networks, end-to-end QoS
provisioning in OBS networks, and some non-mainstream research issues
and future research directions in OBS networks.
