Abstract
This paper presents a novel architecture of synchronous stream optical burst switching (SS-OBS), which employs a unified traffic control plane to enable a wavelength-routed optical network with integrated sub-wavelength grooming services to support sub-wavelength streaming traffic of constant bit rate (CBR) and variable bit rate (VBR) with guaranteed end-to-end delay and data loss rate. SS-OBS shapes sub-wavelength CBR streams into periodic burst trains; aggregates multiple sub-wavelength VBR streams with the same source and destination into a statistically multiplexed periodic burst train. By adopting periodic advanced scheduling of burst trains, SS-OBS substantially decreases recursive signaling processing in supporting sub-wavelength streaming traffic. SS-OBS employs burst train reservation blocking recovery by time-shifting a blocked burst train. Performance of SS-OBS is analyzed in terms of wavelength utilization and data loss. It is found that the performance of the SS-OBS under each type of traffic is compared favorably with other single-service-based OBS schemes
