Message processing method and device

Abstract

The invention discloses a message processing method which comprises the following steps: classifying messages that need to be sent to a central processing unit according to the characteristics of the messages; marking the classified messages with different priorities according to the importance degrees of the messages, then sending the messages after being marked with the priorities into an array of which the priority the same as that of the messages, and carrying out multilevel rate-limiting processing for the array. The invention also discloses a message processing device. By adopting of the invention, the central processing unit can run normally, and then the stable work of network equipment is further maintained.

Description

technical field [0001] The invention relates to message processing technology, in particular to a message processing method and device. Background technique [0002] The wide application of switching chips and network processors has continuously increased the switching capacity of network devices such as Ethernet switches and routers. The more network devices hand over the work of message forwarding to the switch chip or network processor, which can reduce the burden on the CPU. However, according to the current situation, although the switch chip and the network processor can choose which packets should be sent to the CPU and which packets should not be sent to the CPU, they cannot achieve such an ideal situation of sending neither too much nor too little. Moreover, when the network traffic is too large or under network attack, the CPU is often overloaded, resulting in problems such as slow response of network equipment and difficulty in remote maintenance.

Problems solved by technology

However, according to the current situation, although the switch chip and the network processor can choose which packets should be sent to the CPU and which packets should not be sent to the CPU, they cannot achieve such an ideal situation of sending neither too much nor too little.

Moreover, when the network traffic is too large or under network attack, the CPU is often overloaded, resulting in problems such as slow response of network equipment and difficulty in remote maintenance.
