A peer-to-peer network adaptive streaming media on-demand system and service quality assurance method

Abstract

The invention discloses a peer-to-peer network adaptive streaming media on-demand system and a service quality assurance method; the system includes a peer-to-peer network multi-code rate coverage network structure and a client node function module structure, supports HTTP adaptive streaming media technology and peer-to-peer The integration of network technologies such as HTTP enables simple deployment of HTTP adaptive streaming media technology, adaptive bit rate adjustment characteristics and high scalability and low cost of peer-to-peer network technology; the quality of service guarantee method of the system includes Neighbor node search method and self-adaptive code rate control method based on the shape structure; Neighbor node search method based on Fi-power ring structure supports client nodes to efficiently search for neighbor nodes when dragging the playback point, and obtain the required streaming media resources; Adapt to the code rate control method, support the client node to adjust the code rate adaptively according to the relevant service quality indicators, and ensure the user's viewing experience.

Description

technical field [0001] The invention relates to the fields of computer network, peer-to-peer network technology and streaming media technology, in particular to a peer-to-peer network self-adaptive streaming media on-demand system and a service quality assurance method, belonging to the application field of streaming media on-demand services on the Internet. Background technique [0002] Streaming media on demand service has become one of the main applications of the Internet. When implementing streaming media on-demand systems, HTTP adaptive streaming media technology has been widely used. Representative products for commercial deployment include Microsoft's Smooth Streaming (SS), Apple's HTTP Live Streaming (HTTP Live Streaming, HLS), Adobe's HTTP Dynamic Streaming (HTTP Dynamic Streaming, HDS). HTTP adaptive streaming media technology has the following advantages: simple deployment (there is no NAT conversion and firewall problems); it can adaptively adjust the video pla...
