Abstract: This paper analyzes the up-down layer topology of multi-source media streaming network, and presents a topology optimization strategy based on loading balance. This strategy makes use of the abundant network resource by P2P technology and combines media servers function with group broadcasting theory. It can make all media streaming network’s topology balanced, and bring on all system’s loading balanced. Playing delay is reduced, and system stability is enhanced when system expansibility is ensured.

Key words: media streaming network, P2P technology, topology optimization, loading balance
