Weighted Size-Aware Packet Distribution for Multipath Live Streaming
Yiyue Zhang, Chengen Wang, Yifan Gao · 2009
We focus on the problem of packet distribution for live media streaming over multipath networks. After proposing multipath live streaming model and an in-depth analysis of it, we suggest that traffic load should be allocated to paths in proportion to the paths' available bandwidths, considering complicated network status changing as well as burst of media sending rate, that can minimize the bandwidth overload probability. Moreover, weighted size-aware packet distribution algorithm is proposed to avoid the actual traffic deviation from expected due to variance of packet sizes. Simulation results show that the proposed algorithm outperforms other traditional algorithms, especially on reducing late packets, which has negative impact on real-time requirement.
