Embodiment 1

[0035] An embodiment of the present invention provides a CPU protection method in a multi-core network device, such as figure 1 shown, including the following steps:

[0036] Step S101, configure the protection type of each network protocol, the protection type includes common protocol and special protocol;

[0037] The protection type configured for the network protocol is determined according to the importance the user attaches to the protocol packets. If the packets of a certain protocol are important packets, configure the protocol as a special protocol; otherwise, configure it as a common protocol.

[0038] Step S102, regularly calculate the cpu resource occupancy rate of the data core, and when it reaches the preset data core cpu protection execution threshold, execute step S103;

[0039] Step S103, detecting whether the cpu resource occupancy rate of the common protocol in the data core is greater than the preset minimum guaranteed execution threshold of the common pr...

Embodiment 2

[0052] An embodiment of the present invention provides a CPU protection device in a multi-core network device, such as figure 2 shown, including:

[0053] The configuration module 210 is used to configure the protection type of each network protocol, and the protection type includes common protocols and special protocols;

[0054] The calculation module 220 is used to regularly calculate the cpu resource occupancy rate of the data core, and when it reaches the preset data core cpu protection execution threshold, trigger the strategy selection and execution module;

[0055] The policy selection and execution module 230 is used to detect whether the cpu resource occupancy rate of the common protocol in the data core is greater than the preset minimum guarantee execution threshold of the common protocol, and if so, adopt the preset common protocol protection strategy to treat the message of the common protocol otherwise, use the preset special protocol protection policy to proc...

Abstract

The invention discloses a cpu protection method and apparatus in multinucleated network equipment. The method comprises the following steps: configuring a protection type for each network protocol, wherein the protection type comprises a common protocol and a special protocol; calculating a cpu resource occupancy factor of a data nucleus in a timing mode, when the cpu resource occupancy factor reaches a preset data nucleus cpu protection execution threshold, detecting whether the cpu resource occupancy factor of the common protocol in the data nucleus is greater than a preset common protocol minimum guarantee execution threshold, if so, processing messages of the common protocol by use of a preset common protocol protection strategy; and otherwise, processing messages of the special protocol by use of a preset special protocol protection strategy. According to the invention, under the condition that the cpu utilization rate is too high, the messages of the common protocol are preferentially processed, such that it is ensured that important messages are not dropped to the maximum degree, and under the condition that a good protection effect is applied to a cpu, application experience of users is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a CPU protection method and device in multi-core network equipment. Background technique [0002] The purpose of CPU protection is to ensure that network communication devices can adopt effective strategies when they are attacked by a large number of network packets to protect the CPU from working normally and prevent network devices from being paralyzed due to insufficient CPU resources. [0003] At present, the CPU protection strategy is basically implemented as follows: periodically calculate the CPU utilization rate of each network protocol message, and if the CPU utilization rate exceeds a preset threshold, reduce the CPU utilization rate through a certain strategy. The current protection strategy is basically to discard packets that occupy too many CPU resources, so that the CPU can still work normally when it is attacked by network packets. [0004] Although these ...
