Problems solved by technology

At present, in related technologies, a threshold of the total number of packets is preset in the packet receiving queue of the control core to protect the control core from being invalidly occupied by packets exceeding the threshold, but it does not provide protection for the data core, and the data core may still receive A large number of packets that should be throttled

Abstract

The invention discloses a network equipment protection method and device, and the method comprises the steps: discarding a to-be-processed message if a forwarding chip determines that the message feature of the to-be-processed message hits a current limiting control table; if the forwarding chip determines that the message feature of the to-be-processed message does not hit the current limiting control table, forwarding the to-be-processed message to a corresponding data core; if the corresponding data core determines that the to-be-processed message is a control message, transferring the to-be-processed message to a corresponding packet receiving queue in the control core; if the control core determines that the to-be-processed message is the target current limiting message, sending the message characteristics of the to-be-processed message to the current limiting control table. According to the scheme, when the control core detects that the to-be-processed message is the target current-limiting message, the message feature of the to-be-processed message is added into the current-limiting control table item, so that subsequent messages of the same message type are directly discarded by the forwarding chip after arriving without causing invalid occupation to the data core and the control core, and network equipment can be accurately and effectively protected.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a method and device for protecting network equipment. Background technique [0002] A network device configured with a forwarding chip and a multi-core CPU is usually provided with several data cores and control cores. Wherein, the data core is used to process data messages, that is, messages carrying actual application interaction data, and the control core is used to process control messages, for example, management messages for managing the interaction of various applications and determining routing methods routing protocol packets, etc. [0003] After the forwarding chip of the network device receives the message to be processed, it first transfers to the data core. If the data core judges it as a data message, it will be processed by the data core. If the data core judges it as a control message, it will be transferred to the control core for processing. ....
