Title
Dynamic multipath bandwidth provisioning with jitter, throughput, SLA constraints in MPLS over WDM network
Abstract
Multipath bandwidth provisioning is one of the prime interest of next generation optical networks. It is a policy to distribute the requested bandwidth in multiple link disjoint paths on the basis of some optimization function. It also helps to increase network throughput. By using backup path provisioning, we can meet availability requirement of service level agreement (SLA). But multipath bandwidth provisioning leads to problem like jitter which is the difference of delay between two paths. In this paper, we propose a dynamic multipath bandwidth provisioning scheme in telecom mesh network which takes both throughput and jitter into account. It also meets SLA requirement of incoming requests. Our provisioning scheme is dynamic in the sense that it allocates bandwidth for service requests that arrive periodically with no knowledge of future requests and hence requiring an online algorithm. Our algorithm uses 1:N protection scheme against restoration since only protection can guarantee connection availability which is very important to meet SLA. Simulation studies show that efficient multipath bandwidth provisioning using our proposed algorithm can result in total network throughput to be 70% to 90% as well as keeping the effect of jitter that is buffer space overhead to a substantial of 8% to 10% of total load. We will show the simulation result with mean down time 400 second/year and 500 second/year.
