Method for local area network positioning in instantaneous network data transmission

Abstract

The invention relates to a method for local area network positioning in instantaneous network data transmission. The method includes the steps: a), connecting clients; b), recording client information, client IDs (identities), client intranet IPs (internet protocols) and ports and client public network IPs and ports by a server; c), acquiring related information of a target client; d) positioning and judging local area networks; e), if a source client and the target client are in the same local area network, performing direct data transmission; and f), if the source client and the target client are not in the same local area network, adopting an existing data transmission method. According to the method, a sender and a receiver in data transmission are judged whether in the same local area network or not, and then different transmission schemes are adopted according to judgment; if the sender and the receiver are in the same local area network, data is transmitted through the local area network without occupying bandwidth of a public network, so that network resources are saved; meanwhile, by the aid of bandwidth advantages inside the local area network, instantaneity of data transmission is guaranteed, and quality requirements of data transmission are met.

Description

Technical field [0001] The present invention relates to a local area network positioning method in the instant transmission of network data, and more specifically, to a local area network positioning method in the instant transmission of network data that can effectively save public network broadband resources. Background technique [0002] With the rapid development of Internet technology, the application of network real-time data transmission has become more widespread. The typical application of network instant data transmission is mainly instant messaging software like MSN, QQ, etc. In addition, some P2P network video and data transmission download software also involve the instant transmission of network data. There are many types of network data that need to be transmitted instantly, including text data, file data, and streaming media data. These network data for instant transmission often require high transmission quality, and therefore need a better network environment t...

If there is no local area network positioning, it will cause a waste of bandwidth within the local area network

Secondly, contrary to the sufficient bandwidth resources in the local area network, the bandwidth resources of the public network are very tight. If there is no local area network positioning, it is easy to cause the data in the same local area network to be sent through the bandwidth resource outlet of the public network and then returned to the users in the local area network. This situation occupies the egress bandwidth of the LAN and the public network, and at the same time consumes the bandwidth of the public network, resulting in a waste of resources
