Method for dynamically adjusting sharing strategy according to actual network of node

Abstract

The invention provides a method for dynamically adjusting a sharing strategy according to an actual network of a node, and the method comprises the steps: logging in a TS server to obtain a peer list, creating a thread for each peer, carrying out the data penetration through the peer information, sending a heartbeat packet to the node once at an interval of first preset time after the penetration succeeds, and judging whether the heartbeat packet sending time is overtime or not; if yes, accumulating timeout times, determining nodes according to the timeout times in a second preset time, establishing a father-child relationship, updating father-child node intervals by analyzing heartbeat packet information, calculating father-child node interval difference values, and dynamically adjusting a sharing strategy according to the change of the father-child node interval difference values. And various execution instructions of the network are generated according to the strategy. According to the method, the uplink bandwidth of the father node can be utilized to the greatest extent, and meanwhile, other applications of the network where the father node is located are not influenced to use the uplink bandwidth, so that the problem of poor user experience caused by subjective awareness of a user that P2P exclusively occupies the uplink bandwidth is solved.

Description

technical field [0001] The invention relates to the technical field of distributed networks, in particular to a method for dynamically adjusting sharing strategies according to the actual network of nodes. Background technique [0002] P2P is a distributed network in which nodes in the network share their resources and provide services and content through a peer-to-peer network. Nodes (Peer) can be directly accessed without going through an intermediate entity. Each node in this network is both a provider (parent node) and a resource acquirer (child node). [0003] Due to the complex network environment of each node, it is necessary to consider the network environment when nodes directly share resources. At present, there are many resource sharing strategies between P2P nodes, such as fixed bandwidth upper limit, limited number of sharing nodes, or no sharing strategy that restricts exclusive bandwidth. These more or less have some disadvantages, because the network situat...

Problems solved by technology

Then if the upper limit of resource sharing bandwidth or the number of nodes is not appropriate, because each network environment is different, some are not satisfied, and some are not fully utilized

[0006] Therefore, the resource sharing strategy between the current P2P nodes, because the massive node network situation is very complicated, some uplink bandwidth is extremely small, some network environments are unstable, and some network uplink bandwidth is occupied by other devices, either wasting uplink bandwidth, or Monopolizing the upstream bandwidth leads to disgust of users. All kinds of situations directly affect the stability of shared data and user experience
