Abstract

In this paper, we show how Disjoint Multipath QoS Routing (DMQR) can cooperate with importance-based video layering to achieve reliable video transmission. DMQR algorithm dynamically searches for multiple paths for a flow in an overlay network. The multiple paths selected are mutually disjoint w.r.t. bottleneck links, each of which is the shortest among the widest ones. An importance-based video layering and transmission would be most effective to cooperate with DMQR to deliver satisfactory video quality. The video layering will produce a base layer and a bit-plane-wise enhancement layer. The base layer consists of some vital information, sign bit plane and a few significant bit planes; its packets are most important, will be fully FEC protected and duplicated over multipath selected by DMQR. The enhancement layer includes the rest bit planes; its packets will be FEC protected partially and distributed over multiple paths. Simulation results demonstrate that both layers can be transmitted with improved bandwidth efficiency and end-to-end path reliability with shorter one way delay and jitter.
