ABSTRACT
The inability of wavelength conversion between links in All-Optical networks causes congestion and hence results in Packet loss. We have Proposed a GMPLS-Based All-Optical networks that would dynamically locate path for switching in case of congestion, using maximum utilization of Control Plane resources thus ensuring guaranteed QoS. This paper presents the mechanism to reduce the blocking probability in GMPLS by dynamically finding a route and selecting a wavelength in a manner that minimizes the overall blocking probability using Least Routing mechanism (LR). Simulation results confirm our analysis and furthermore, reveal that our proposal also complete major performance improvement in terms of blocking probability.
