Problems solved by technology

[0003] However, in related technologies, after the service message arrives at the switch chip, the switch chip will perform three-layer forwarding on the service message, and the three-layer forwarding will modify the field information of the service message, for example, modify its MAC (Medium / Media Access Control , Media Access Control) address and TTL (Time To Live, time-to-live) value, so that the service board cannot normally process the service message, for example, when the service board judges the legality of the service message through the MAC address , if the MAC address of the service message (including the source MAC address and the destination MAC address) is modified, it may cause the service board to fail to correctly determine whether the service message is legal, resulting in network attacks and affecting the performance of distributed network devices

Abstract

The present invention provides a method and device for service processing. The method is applied to network equipment. The network equipment includes a switch chip and a service board. The method is executed by the switch chip, including: receiving service messages; The identification information of the service message is matched in the ACL rule table, and the ACL rule table includes the corresponding relationship between different identification information and processing actions; when the identification information of the service message is matched, the corresponding The processing action is to send the service message to the target service board, so that the target service board performs service processing on the service message. By applying the embodiment of the present invention, the field information of the service message will not be modified, but will be sent to the target service board intact, thereby ensuring that the service board can normally process the service message.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for service processing. Background technique [0002] After the distributed network device receives the service message, in order to improve the performance of the device, the switching chip in the distributed network device can divert the service message to the service board, so that the service board can forward and audit the service message. deal with. [0003] However, in related technologies, after the service message arrives at the switch chip, the switch chip will perform three-layer forwarding on the service message, and the three-layer forwarding will modify the field information of the service message, for example, modify its MAC (Medium / Media Access Control , Media Access Control) address and TTL (Time To Live, time-to-live) value, so that the service board cannot normally process the service message, for example, when the service boa...
