Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The embodiment of the present application provides a method for preventing multicast flooding. The embodiment of the present invention provides a method for preventing multicast flooding. Refer to figure 1 , figure 1 It is a schematic flowchart of a method for preventing multicast flooding in the present invention.

[0043] Step S10, receiving a multicast data packet sent by any networking node, and extracting identification information of the multicast data packet;

[0044] Step S20, comparing the identification information with the preset node information to obtain a comparison result, and if the comparison result is a successful comparison, it is determined that the multicast data packet is a data packet to be rebroadcast;

[0045] Step S30, discarding the multicast data packet.

Abstract

The invention discloses a multicast flooding prevention method, device and equipment, and the method comprises the steps: receiving a multicast data packet sent by any networking node, and extracting the identification information of the multicast data packet; comparing the identification information with preset node information to obtain a comparison result; if the comparison result is that the comparison is successful, determining that the multicast data packet is a multicast data packet to be de-reconfigured; and discarding the multicast data packet. According to the invention, multicast flooding can be effectively prevented.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, device and equipment for preventing multicast flooding. Background technique [0002] When transmitting data in the networking, the data can be transmitted to each node by means of unicast, broadcast and multicast. [0003] In the existing technology, most of them use multicast to transmit data. The advantage is that the source node only needs to send data once, and the multicast group nodes can receive the data, and the source node will not send it to other nodes outside the group. Other nodes that need this data; however, when using multicast to transmit data, after the source node sends the data, the multicast group nodes will forward the data between the multicast group nodes after receiving the data, resulting in multicast Group nodes repeatedly receive the same data, forming a multicast storm, that is, multicast flooding. [0004] That is, t...
