Embodiment 1

[0018] An embodiment of the present invention provides a network speed limiting device, which is applied to network equipment, and the network equipment includes several ports. Please refer to figure 1 The basic hardware running on the device includes CPU, memory, non-volatile memory and various hardware. The CPU can perform related operations by executing related instructions stored in the memory, thereby realizing speed limit. Specifically, the CPU can execute related The command receives the protocol message sent from each port; and when the speed of receiving the protocol message is greater than the preset first speed limit value, obtains the speed of sending the protocol message on each port, and sends the protocol message upwards. The port whose speed of the protocol packet is greater than the preset second speed limit value issues a rate limiting rule, so that the port issues the rate limiting rule on its own port to limit the rate of the protocol message. In this way,...

Embodiment 2

[0020] An embodiment of the present invention provides a network speed limiting device, which is applied to a network device, the network device includes several ports, and the device includes a receiving unit 01 and a processing unit 02, such as figure 2 shown.

[0021] Wherein, the receiving unit 01 is used for receiving protocol packets sent from each port. Normally, the protocol packet received by the port cannot be directly forwarded, so it is sent to the receiving unit 01 for the processing unit 02 to process the protocol packet. It should be noted that the port will receive various types of protocol messages, which can be distinguished by the message format, so that the technical solution provided by the present invention can limit the speed of different protocol messages .

[0022] When the receiving unit 01 receives the protocol message, the processing unit 02 usually obtains the speed at which the receiving unit 01 receives the protocol message periodically, and c...

Embodiment 3

[0041] The implementation of the present invention provides a network speed limiting method, which is applied to network equipment, and the network equipment includes several ports. Please refer to image 3 , the method may include the following steps:

[0042] Step 101, receiving the protocol message sent on each port;

[0043] Step 102, when the speed at which the protocol message is received is greater than the preset first speed limit value, obtain the speed at which each port sends the protocol message, and send the protocol message upward at a speed greater than the preset first speed limit value. The port with the second rate limit value issues a rate limit rule, so that the port issues the rate limit rule on its own port to limit the rate of the protocol packet.

[0044] The execution subject of the method in this embodiment may specifically be the above-mentioned speed limiting device, so as to limit the speed at which the ports in the network receive protocol packe...

Abstract

The invention provides a network speed limiting device, which includes a receiving unit and a processing unit. The present invention also provides a network speed limit method, the method includes: receiving the protocol message sent from each port; when the speed of receiving the protocol message is greater than the preset first speed limit value, obtaining The speed at which protocol packets are sent, and the speed limit rules are issued to the ports whose speed of sending protocol packets is greater than the preset second speed limit value. Through the above technical scheme, the present invention sends speed limit rules to ports that need speed limit according to the speed at which each port sends the protocol message, effectively avoiding the waste of speed limit rules for each port in the prior art. Shortcomings of hardware resources.

Description

technical field [0001] The invention relates to the technical field of network speed limiting, in particular to a network speed limiting device and method. Background technique [0002] With the continuous development of network technology, various network security problems are becoming more and more serious, such as network attacks and broadcast storms. When a network attack against a certain protocol occurs, a large number of malicious packets of this protocol will appear in the network. In a network device, protocol packets are processed by the CPU on the device. Due to the limited processing capacity of the processor (CPU), when a large number of protocol packets appear in the network, the CPU is easily overloaded and caused The device is paralyzed, or the normal processing of other service packets is affected. [0003] In the prior art, the CPU speed limit is usually used to process the received protocol packets, that is, the number of packets received by the CPU withi...
