Distributed Traffic Grooming Multipath Routing Algorithm for All Optical WDM Networks

In this paper, the authors have presented an efficient traffic grooming algorithm (DTMR) for selecting the optimal path based on the varying traffic load conditions. In this algorithm, the initial incoming packets are sent through all the possible paths. With the monitored values on each path, the source estimates the blocking probabilities of each path and the source node selects the best three paths. Then the traffic is classified into high priority and low priority by the source. Subsequently, they are classified into high speed and low speed traffic. High priority high speed data is sent through primary path. Low priority high speed data is sent through secondary path.
