Service Differentiation in Wavelength-Routed Optical Burst-Switched Networks

Not Accessible

Your library or personal account may give you access


The optical burst-switched network architecture (OBS) has been shown to provide potentially a higher degree of the utilisation of optical bandwidth in the IP-centric networks with regards to static wavelength-routed optical networks (WRONs).1 However, most currently proposed OBS schemes suffer from high packet loss rate and assume processing in the optical domain and full wavelength conversion.2 As an alternative to the OBS, the wavelength-routed optical burst-switched architecture (WROBS) was proposed3 in order to efficiently utilise the bandwidth whilst avoiding processing in the optical core by means of the dynamic wavelength routing and assignment (dynamic RWA). This paper investigates the QoS provisioning in WROBS4 for the case of the service differentiation between multiple classes of traffic.
