Abstract

The present invention discloses a method for scheduling resources of a live streaming media system under a CDN-P2P hybrid architecture, and achieves highly efficient use of the network resources. Basic ideas of the method are: a peer first divides various video data blocks in cache into urgent or non-urgent data blocks according play time thereof, then determines to request a server or the other peers for the data block based on attributes of the data block; a CDN server uses a method of weighting equal queues to classify the data block requests, and dynamically adjusts the weight assigned to each queue, thereby achieving use and distribution of the server resources. The present invention has the advantages such as highly efficient use of the resource, low packet loss probability of the system.

Description

technical field [0001] The invention relates to a method for efficiently utilizing resources of a live streaming media system based on a CDN-P2P hybrid architecture, specifically a method for scheduling and allocating CDN server and peer resources, belonging to the field of network data communication. Background technique [0002] In recent years, the use of the Internet to transmit TV signals has become an increasingly popular network application. It provides users with rich, convenient and interactive video multimedia services, and has formed a large-scale industry. Traditional video program distribution adopts cable TV cable distribution, which has high signal quality, but the system price is high and the system architecture cannot flexibly cope with the development of new services. With the development and popularization of network technology, it is an inevitable choice to transmit video programs through IP network, but the use of a large number of users will lead to a s...
