Project Abstracts Return to QoS Routing for VoIP Projects

Learning Minimum Delay Paths for VoIP in Service Overlay Networks
 

Student: Hong Li, PhD student
Supervisors: Prof. Lorne Mason & Prof. Michael Rabbat

Abstract: We developed active probing strategies and applied stochastic automata to learn the best paths from feedback of the network. The simulation results show that the active probing and learning method can find a better path than the minimum hop path in terms of the mean network delay. It takes around 1000-2000 probes for the learning automata with an appropriate gain to learn the optimal paths. The convergence speed scales well with overlay network sizes.
