Parameterization of virtual source multicast OBS based on QoS constraints

摘要

The issue of multicast routing in TCP over Optical Burst Switched (OBS) networks was dealt before and here few parameters are presented to determine the efficiency of the OBS Virtual Source heuristic. Such QoS parameters include Burst Throughput (η), Burst Latency (τ) and Burst Loss Probability (φ). It is mathematically proved that using the Virtual Source (VS) heuristic for OBS Networks under TCP protocol, the throughput is increased while maintaining a minimum Burst Loss Probability and Latency.
