Flow-guiding function-supported application identification equipment and method

Abstract

The invention relates to flow-guiding function-supported application identification equipment and a method. The equipment comprises a connection tracking module, a first packet identification module and a flow-guiding module. The connection tracking module receives a data packet from a terminal, judges whether the data packet is a first packet of a new connection or not according to the data packet, and records the new connection if the data packet is the first packet of the new connection. The first packet identification module receives the first packet from the connection tracking module, matches one or more information in the quintuple of the first packet with each table entry of a relevant table; and if matched table entries exist, corresponding application in the table entries are extracted, wherein the quintuple information and the corresponding application of each connection are stored in the relevant table. The flow-guiding module guides the first packet to a corresponding link based on the first packet from the first packet identification module, the application to which the first packet belongs, and an inbuilt flow-guiding strategy. With the adoption of the flow-guiding function-supported application identification equipment and the method, provided by the invention, the first-packet flow-guiding function of connections is realized, thus the flow-guiding function-supported application identification equipment and the method can be widely applied to various network equipment.

Description

Technical field [0001] The invention relates to a computer network, in particular to the drainage function of network equipment. Background technique [0002] The flow diversion function refers to directing traffic to the appropriate link based on the application identification result and user policy. For example, the user has two links, link A and link B, link A has a small delay but small bandwidth, and link B has a large delay but large bandwidth; the user’s strategy is to direct important business traffic to the chain. Route A, such as leading the video conference to the link A, lead the unimportant business traffic to the link B, such as leading the P2P download traffic to the link B, to improve work efficiency and network resource utilization. [0003] It can be seen that, to divert service traffic, the specific application of the traffic must first be identified, that is, the application of the traffic must be identified first. In other words, only applications that identi...

Problems solved by technology

[0006] Therefore, the existing technology cannot guarantee the identification of the first packet of each connection, and it cannot realize drainage in the first packet of the connection, so that the drainage function cannot be ensured without interrupting the connection.
