Embodiment Construction

[0013] The embodiment of the present invention provides a flow control method of a peer-to-peer network, after judging that the P2P protocol message is the response message ACK1 of the P2P network user's request to obtain the P2P resource, the P2P nodes with the P2P resource are prioritized And encapsulate it into a new response message ACK according to the sorting result 2 , the response message ACK 2 sent to the user to enable the user to establish a connection with the corresponding P2P node. The embodiment of the present invention also provides a corresponding routing device and a communication system. Each will be described in detail below.

[0014] Please refer to figure 1 , a schematic flowchart of a flow control method for a peer-to-peer network provided in Embodiment 1 of the present invention, which mainly includes:

Abstract

The embodiment of the invention provides a flow control method of a peer-to-peer (P2P) network. The method comprises the following steps of: receiving a network message and extracting a P2P protocol message in the network message; judging whether the P2P protocol message is an acknowledgement 1 (ACK1) message required to be acquired by a user or not; if the P2P protocol message is the ACK1 message required to be acquired by the user, optimizing a P2P node list to ensure that a local P2P node owning a P2P resource is arranged in front of a nonlocal P2P node owning a P2P resource; and encapsulating the optimized P2P node list into a new ACK2 message and transmitting the ACK2 message to the user, so that the user can establish connection with a corresponding P2P node according to the optimized P2P node. By adopting the method, P2P flow is changed into ordered from confused, the bandwidth of a local network is effectively utilized, the outlet bandwidth of a metropolitan area network is reduced, and closing costs among operators are saved.

Description

technical field [0001] The invention relates to the field of metropolitan area network, in particular to a peer-to-peer network flow control method, routing equipment and communication system. Background technique [0002] Peer-to-peer network (P2P, Peer to Peer) is a network model different from the client / server (C / S, Client / Server) model. Under the P2P network model, any one of the two P2P nodes (Peer) is both a client and a server, and the two establish connections to transmit data, and the same Peer can establish peer-to-peer relationships with multiple Peers. relation. In a P2P network, a Peer can request resources from any possible Peer, so any Peer can make great use of network resources. It is precisely because of the above characteristics of P2P networks that peers in P2P networks can grab and utilize network resources endlessly, making some P2P-based applications occupy network bandwidth without limit and are difficult to identify and control. In order to reduc...
