Problems solved by technology

[0004] However, there is a problem with the above-mentioned P2P data transmission method: at present, the timeout retransmission interval for all users is a fixed value, but due to the complexity of the network environment, the network environment between different Peers is different, and the network between the same two Peers at different times There are also differences in the situation, so it will inevitably cause the speed of transmitting data packets

Embodiment Construction

[0063] The network environment between different Peers in P2P is different. If other network applications occupy the user's bandwidth at different times between the same two Peers, the network conditions will also be different. In order to utilize the maximum communication capability of each Peer in a heterogeneous network at a specific moment, the present invention proposes to formulate a sending and retransmission strategy adapted to the network situation according to different network conditions. Obtaining the network status between Peers in the present invention is achieved by continuously measuring the network distance during the Peer communication process, using the network distance as a reference and basis for data interaction between the two parties in communication, and obtaining accurate information based on different network distances The timeout retransmission interval further allocates bandwidth for each Peer, maximizes the use of bandwidth, and achieves the purpos...

Abstract

The invention supplies a method to gain network time-out re-transferring time span that could gain the time span between gaining send request report and receiving the response report and calculate the time-out re-transferring time span. The invention also supplies a method for network data transferring that includes the following steps: sending request report; receiving response report; gaining the time span between the previous two steps; calculate the time span of time-out re-transferring; when transferring next data, sending request report according the time span. The invention could make the most of bandwidth and improve data transferring ratio.

Description

technical field [0001] The invention relates to computer network technology, in particular to a method for obtaining the overtime retransmission interval in the network and a data transmission method. Background technique [0002] P2P (Peer to Peer, peer-to-peer interconnection) means that the network enables online users to directly link to other users' computers for file sharing and exchange, making network communication simpler and more direct. Since P2P is arbitrarily used in a distributed architecture to provide direct communication applications or processes between autonomous resources without central coordination and management, it changes the working mode of the previous server Server, and the server only completes the necessary functions of coordination and management of Peer. Most tasks are completed interactively between peers. At present, the applications based on P2P technology can be mainly divided into instant messaging, file sharing, collaborative office and...
