Message process device

Abstract

The apparatus comprises: multi interface units and multi service processing units. Anyone interface unit can be connected to anyone service processing unit via first connection unit; the interface unit are used for selecting a service processing unit from all service processing unit after receiving the message, and sending the message to the service processing unit via the first connection unit; the service processing units are used for processing the message after receiving the message. In the invention, the interface units and service processing units doesn't have the binding relation anymore; the message incomes from any interface unit can be allocated to any message processing unit.

Description

technical field [0001] The invention relates to network communication technology, in particular to a message processing device. Background technique [0002] In the network, in order to enable the four-layer to seven-layer L4~L7 network equipment (for convenience of description, hereinafter collectively referred to as L4~L7 network equipment) to perform various business processing on packets of a service flow, that is, a session, the L4~L7 network A typical switching architecture inside a device 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 wi...

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 interface 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, it will cause some service processing units to The business load is too heavy, and the message processing speed is reduced, which becomes the bottleneck of the message processing of the L4~L7 network equipment, while other service processing units are idle, which greatly reduces the message processing capacity of the 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
