Problems solved by technology

However, the current P2P design scheme mostly refers to the design of the WebCache server for the organization of the Cache internal server, without considering the characteristics of P2P applications and traffic, and cannot fully meet the needs of efficient caching of P2P content
[0007] The current P2P traffic optimization technology is not universal. Although the P2P Cache solution is suitable for all P2P traffic, it has great defects in the cache hit rate and utilization rate, and cannot meet the high efficiency and low cost design of P2P Cache. need

Abstract

The embodiment of the invention provides a method and a device for video on demand (VoD) cache replacement based on predicted weight. The method comprises the steps of: recording request times for a video segment when a VoD request of a user on the video segment is received, and updating the segment weight of the video segment and the segment weight of each video segment after the video segment in a video according to the request times of the video segment; and in a cache regulation period of the video, regulating the cache size of the video according to the video weight of the video, the sum of the video weights of all the videos on a server and the cache size of the server. According to the invention, more hot videos and hot segments can be cached, so that the vision experience for user VoD is promoted.

Description

technical field [0001] The invention relates to the field of Internet video-on-demand, in particular to a buffer adjustment method and device for video-on-demand. Background technique [0002] With the significant development of peer-to-peer network technology (Peer-to-Peer, P2P) applications, services such as P2P file sharing, P2P video live broadcast, and P2P video-on-demand have generated a large amount of P2P traffic, occupying network operators (Internet Service Providers, ISPs). Most of the bandwidth has brought a heavy economic and management burden to the ISP. Especially in recent years, with the gradual popularity of P2P video-on-demand services such as Youtube, PPLive, and PPStream, P2P traffic has shown an explosive growth trend. At present, domestic operators generally adopt a pricing strategy based on fixed bandwidth. ISPs are not only unable to obtain income from the rapidly growing P2P traffic, but also need to continuously increase additional investment to i...
