Embodiment 1

[0023] A P2P optimized transmission method based on a multimode terminal, the steps of which are as follows:

[0024] Step 1: A node joins the P2P network, and a node information module and a routing strategy maintenance module are set in the system where the P2P network is located.

[0025] The node information module is automatically loaded in the system where the P2P network is located, and is used to automatically maintain the information of each node. The node information module is expanded on the basis of the existing P2P protocol. The node information module includes a node information maintenance unit and a local information maintenance unit. Each node will store a node information table locally, which records the nodes corresponding to the associated resources and the usage status of each interface of the node. The local information maintenance unit is used to maintain the node information table of the local node, that is, to detect the use status of each interface ...

Embodiment 2

[0041] A P2P optimized transmission method based on multi-mode terminals, such as figure 2 As shown, several nodes in the P2P network, namely node A, node B, node C, node D, node E..., each node will store a node information table locally, which records the node corresponding to each resource and each interface of the node usage status. For example, in the node information table of node B, there are the usage states and resource names of the interfaces of nodes A, D and E. The local information maintenance unit in the node information module maintains its own node information table, and the node information maintenance unit maintains the node information table of the associated nodes. Node A is a multi-mode terminal, which owns the resource "The Legend of Zhen Huan". Node A will periodically notify Node B, which saves the resource, through standard P2P message interaction. The interface information field is added in the standard P2P message interaction, and the current stat...

Abstract

The invention discloses a P2P optional transmission method based on a multi-mode terminal. The method comprises the following steps that: nodes are added into a P2P network, and a node information module and a routing strategy maintenance module are arranged in a system in which the P2P network is located; the node information module periodically maintains an interface state of each node and a resource situation; the routing strategy maintenance module dynamically maintains a routing table and strategy routing according to the current situation of each interface of the nodes; one node requests resources based on a P2P protocol; the request node retrieves node information tables of correlated nodes through the node information module, and locates a resource node; the request node initiates a connection request to the resource node, and the node information module judges an interface state of the resource node; and the routing strategy maintenance module establishes strategy routing for a selected interface, and the request node establishes connection with the interface of the resource node to start data transmission. According to the multi-interface characteristic of the multi-mode terminal, the P2P protocol is optimized, and the download efficiency and upload efficiency are increased.

Description

technical field [0001] The invention relates to the technical field of P2P transmission, in particular to a P2P optimized transmission method based on multi-mode terminals. Background technique [0002] In a standard P2P protocol, each node acts as both a server and a client. Therefore, when a node is downloading resources, it will also serve as the server side of the resources. The standard P2P protocol framework only provides support for single-interface terminals, that is, when a node downloads resources through one of its interfaces, if it needs to upload resources, the interface for downloading resources is still used. At present, multi-interface terminals are becoming more and more popular. Usually, a communication terminal is equipped with WIFI, 3G, LTE and other interfaces. If the advantages of multiple interfaces can be fully utilized, the quality and efficiency of terminal communication can be greatly improved. [0003] Existing P2P protocols can well support dat...
