BCBS: An Efficient Load Balancing Strategy for Cooperative Overlay Live-Streaming

In this paper, we present Bandwidth Class Based Streaming (BCBS), an application layer multicast for multimedia services. BCBS focuses on multi source live streaming, and following a locality model based on round trip times, it creates network efficient streaming meshes. The load balancing selects multiple nodes as streaming sources and is organised subscription based instead of request based. We describe a simulation study of the load balancing and tree construction procedures. The results show that BCBS creates network efficient overlays with respect to stretch and link stress.
