Problems solved by technology

CDN technology is to deploy cache servers on the edge network to improve the service capability of the system, but the cost is high and the dynamics are poor
P2P uses the computing, storage and bandwidth resources of the client to improve the service capability of the system through the cooperation of the client, but it brings management difficulties and complex systems.

Embodiment Construction

[0023] The system structure of the present invention is as figure 1 shown. The streaming media system includes several roles of video server, client, general router, and cache router. The functions of the video server include publishing and serving the original video content, statistics and billing, updating cache routers and other functions. Clients are the end users most receptive to streaming services. General routers perform general routing and forwarding functions and do not participate in video data caching. The caching router is the main role in it, caching video data serving its neighboring clients.

[0024] Compared with general routers, cache routers have the following characteristics.

[0025] 1. If figure 1 As shown, the cache router should be an edge router. Compared with the routers on the network, the edge router is the router closest to the client, which can directly serve the video cache data to the client, shorten the path length of video data transmiss...

Abstract

The invention aims to provide a streaming media system accelerating method based on the router cache, which not only adopts the basic function of a router for storage and transfer, but also adopts the functions of the router to buffer the memory of streaming media data and to respond to requests of a user. Therefore, the streaming media data are closer to the user, thereby reducing the initial delay of the low-end system in video playing and easing the burden of the server. The invention can improve the performance of the streaming media system, reduce the total bandwidth consumption on the network and the access delay of the client, and not only reduce the load of the video server but also increase the total number of the users the system can provide service for.

Description

technical field [0001] The invention belongs to the technical field of video-on-demand systems and multi-core router buffers, and in particular relates to a router buffer-based streaming media system acceleration method. Background technique [0002] In order to improve the performance of the streaming media system, CDN and P2P technologies have been developed successively and have achieved great success. CDN technology is to deploy cache servers on the edge network to improve the service capability of the system, but the cost is high and the dynamics are poor. P2P uses the client's computing, storage and bandwidth resources to improve the service capability of the system through the client's cooperation, but it brings management difficulties and complex systems. These two technologies optimize from the perspectives of the client and the server, but ignore the role that also plays an important role in network transmission - the router. [0003] Traditional routers only pla...
