Stream recognition method and bandwidth management device

Abstract

The invention discloses a flow identification method which is applied to a bandwidth management device used for connecting the interior and the exterior of a management zone. The interior of the management zone includes at least one internet user, and the exterior of the management zone includes at least one internet user. The method comprises the following steps: the statistical values of the connection number terminated by a destination in a dialog started by an IP is obtained; the obtained statistical values of the connection number terminated by the destination in the dialog started by the IP and the preset threshold are compared, if the obtained statistical values of the connection number exceeds the threshold, the IP is considered to be using the P2P software, and the unknown flow taking the IP as a source end or destination is P2P flow. The invention avoids missing reports and false reports of P2P internet applications, load encrypted P2P flow and the unknown flow for the P2P software using a variable port or a disguise port.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a flow identification method and bandwidth management equipment. Background technique [0002] All nodes in a P2P (Peer-to-Peer) network are peer-to-peer, and the nodes share information resources or file exchanges through direct interconnection, without relying on centralized servers. Therefore, P2P technology promotes the development of the Internet, enabling users to share various resources more conveniently. [0003] At the same time, the negative impact of P2P applications on the network cannot be ignored. For example, when multiple pairs of nodes in the network use P2P communication at the same time, it will take up a lot of bandwidth, cause network congestion, greatly reduce network performance, and degrade network service quality. The normal network business development and key applications have seriously affected users’ normal Web, E-mail and other applications...

AI Technical Summary

Problems solved by technology

[0005] The existing technology has the following disadvantages: with the development of P2P software, P2P application software using variable ports and disguised ports has appeared, and the problem of port identification method false positives has become more and more prominent.

Therefore, in the prior art, it is impossible to quickly and efficiently identify that the user is using the P2P application software, and then realize the control of the P2P traffic.
