Problems solved by technology

At present, when a network device is attacked by a large number of packets that need to be sent to the CPU (including multicast packets and unicast packets sent to the local machine), due to the limited processing capability of the CPU, The forwarding queue will be blocked because the CPU cannot process it in time, causing subsequent packets sent to the CPU to be discarded
If the discarded packets are protocol packets or management packets, the protocol may be interrupted and the device cannot be managed.

Embodiment Construction

[0021] In the prior art, since some protocol packets and some data packets that need to be processed by applications are sent to the central processing unit CPU for processing, some attackers send a large number of protocol packets to the CPU to carry out packet attacks. When the CPU is attacked by a large number of packets, it is very likely that it will be blocked because it cannot process it in time, and subsequent packets sent to the CPU will be discarded. If the discarded packets are management packets or other important packets, the As a result, the device cannot be managed or the protocol is disconnected. Most of the current solutions reduce the number of packets sent to the CPU by limiting the rate of each protocol or port. However, the rate limit only reduces the number of packets sent to the CPU according to the protocol and port, and it still cannot achieve better results when there are many types of packets.

Abstract

The invention provides a message processing method. The method comprises: generating a control strategy with a queue priority according to message characteristics; sending the control strategy to a forwarding chip, adding the messages with the message characteristics in the control strategy to a message forwarding queue corresponding to the queue priority by the forwarding chip; receiving the messages sent by the forwarding chip according to the queue priority of the message forwarding queue, so that the important messages in the message forwarding queue with high queue priorities are processed preferentially, and a network fault is avoided.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message processing method, device and network equipment. Background technique [0002] With the advancement of network communication technology, network security issues caused by various network attacks have attracted increasing attention. At present, when a network device is attacked by a large number of packets that need to be sent to the CPU (including multicast packets and unicast packets sent to the local machine), due to the limited processing capability of the CPU, The forwarding queue will be blocked because the CPU cannot process it in time, and subsequent packets sent to the CPU will be discarded. If the discarded packets are protocol packets or management packets, the protocol may be interrupted and the device cannot be managed. Contents of the invention [0003] In view of this, the present invention provides a message processing method and device...
