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 reasonableadjustment of the number of the neighbor nodes of the P2P client.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method and device for controlling the number of neighbor nodes of a client, and a cache system. Background technique [0002] Peer-to-Peer (Peer-to-Peer, P2P for short) video live broadcast services are more and more widely used. For example, P2P can be used in school dormitories, libraries and other wireless LANs to provide live video services. figure 1 The architecture 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 cache server 12 is set up between the wireless local area network of the P2P system and the Internet 11. The cache server 12 can promote the sharing of download data among wireless local area network users, so that some audiovisual data that has been downloaded can be cached Download on the server, thereby saving external network bandwidth and ...

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
