A limited bandwidth resource scheduling algorithm for a streaming media system

摘要

With the development of streaming media technology, streaming media services are widely used. In the case of limited bandwidth resources in the streaming media system and the bandwidth fluctuation of user requests, how to ensure the quality of the streaming media service is an important problem. In this paper, a limited bandwidth resource scheduling algorithm for a streaming media server was proposed. The proposed algorithm, including a load-balancing algorithm, migration scheduling algorithm and error service migration scheduling algorithm, is intended to solve the problems of the bandwidth resource load balancing of new users, service migration on the full-load server and service migration on a faulted server. Our algorithm outperforms other load-balancing algorithms by 3% in the request success rate, by an order of magnitude for load balancing and by a server not under a full load, and outperforms other migration-scheduling algorithms by 5% on load balancing and has a better performance under a full load.
