A packet processing method

Abstract

The invention discloses a message treatment method. A connection unit is equipped between every interface unit and every business treatment unit of L4-L7 network equipment. After receiving the message from outside, any interface unit chooses business treatment unit and sends the message to the chosen business treatment unit by a connection unit. After receiving the message, the chosen business treatment unit carries out business treatment on the message. In the invention, because of no binging relation between the interface and the business treatment unit of L4-L7 network equipment, the message from any interface unit can be distributed to any message treatment unit, in order to facilitate L4-L7 network equipment to flexibly utilize every message treatment unit and improve the message treatment capability of L4-L7 network equipment.

Description

technical field [0001] The invention relates to network communication technology, in particular to a message processing method. Background technique [0002] In the network, in order to enable Layer 4 to Layer 7 network devices (for ease of description, hereinafter collectively referred to as L4-L7 network devices) to perform various business processing on packets of a service flow, that is, a session, the typical L4-L7 network devices The switching architecture of the system is mainly composed of a main control unit, a service processing unit and an interface unit. [0003] FIG. 1 is a schematic diagram of the internal structure of L4-L7 network equipment in the prior art. Referring to Figure 1, at present, the typical switching architecture inside L4-L7 network equipment is: each interface unit connected to the outside of the L4-L7 network equipment is fixedly connected with each service processing unit, and all service processing units communicate with the main control u...

Problems solved by technology

[0004] It can be seen from the above description and Figure 1 that in the prior art, the interface units and service processing units of L4-L7 network equipment are bundled together, that is, one service processing unit can only be fixedly connected to one interface unit, so , each service processing unit can only process the packets of the interfaces bound to it. If the traffic of some interface units in the L4~L7 network equipment is too large, while the traffic of other interface units is too small, some service processing units will The business load is too heavy, and the message processing speed is reduced, which becomes the bottleneck of network equipment message processing, while other service processing units are idle, which greatly reduces the message processing capacity of L4~L7 network equipment

[0005] Furthermore, in the prior art, if a service processing unit of the L4-L7 network equipment fails, all services processed by the service processing unit will be interrupted, thereby greatly reducing the business service quality of the L4-L7 network equipment
