Method for controlling number of neighbor nodes of client and device and cache system thereof

Abstract

The embodiment of the invention discloses a method for controlling the number of neighbor nodes of a client, and a device and a cache system thereof, wherein the method comprises the steps of receiving a connection request message sent by the client and used for requesting the establishment of the connection with the neighbor nodes, wherein the connection request message includes data download rate of the client and the number of the neighbor nodes which are connected currently; obtaining the threshold of the number of the neighbor nodes of the client according to the data download rate; and rejecting the connection request of the client when the connecting number of the neighbor nodes which are connected currently of the client is equal to the threshold of the number of the neighbor nodes. The embodiment of the invention can avoid a large amount of unnecessary additional bandwidth consumption due to an excessively large number of the neighbor nodes, and realize the dynamic reasonable adjustment of the number of the neighbor nodes of the P2P client.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and device for controlling the number of neighbor nodes of a client, and a caching system. Background technique [0002] Peer-to-Peer (Peer-to-Peer, P2P for short) live video services are more and more widely used. For example, live video services can be performed in a P2P manner in wireless local area networks such as school dormitories and libraries. figure 1 The structure diagram of the P2P video live broadcast system in the wireless local area network provided for the prior art, such as figure 1 As shown, a caching server 12 is set up between the wireless local area network of the P2P system and the Internet 11, and the caching server 12 can promote the sharing of downloaded data between wireless local area network users, so that some downloaded video and audio data can be downloaded from the cache Download on the server, thereby...

Problems solved by technology

[0003] However, the inventor found in the process of implementing the present invention that the P2P video live broadcast system in the prior art may change the actual transmission situation during actual operation, for example, the program source required by the client is in the connected neighbor node If there is none, or the number of neighbor nodes with program sources is small, the average download rate of the client will decrease at this time, and the connection quality will deteriorate, so the scale of neighbor nodes needs to be further expanded; The number is relatively fixed, and the value of the upper limit of the number of connections cannot be dynamically adjusted in real time during operation. Even if the client resets the upper limit of the number of connections, the upper limit of the number of connections it sets may be too large , may still introduce too much signaling data, resulting in a certain waste of bandwidth
