Dynamic establishment of differentiated survivable lightpaths in WDM mesh networks
In the emerging next-generation transport networks, called intelligent optical transport networks, DWDM-based optical components like add-drop multiplexers and optical cross connects will have full knowledge of the wavelengths in the network, status, and traffic carrying capacity of each wavelength. With such intelligence, these intelligent optical networks could create self-connecting and self-regulating connections on-the-fly. Because these networks carry huge volume of traffic, maintaining a high level of service availability at an acceptable level of overhead is an important and critical issue. It is essential to incorporate fault-tolerance into QoS requirements. Since the delay (response time) becomes unbounded as the load approaches the link capacity, delay is usually dominated by the most heavily loaded links; therefore algorithms must attempt to minimize the delay. In this paper, we take fault-tolerance, delay, bandwidth, and availability as QoS parameters to provide varying c...
