Abstract

The invention provides a message processing method and device. In the embodiment, network equipment generates an ACL table item comprising an MAC address and retransmission information, and retransmission control is applied to the data type message through the generated ACL table item. When the ACL table item which is matched with the received data type message is inquired, the network equipment can retransmit the received data type message through the retransmission information in the ACL table item, otherwise, the received data type message is thrown away. According to the message processing method and device, retransmission control of the data type message is realized, the probability of attack passages passing through the network equipment is effectively reduced, the network attack risk of the network where the network equipment is located is reduced, and the network security is improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a message processing method and device. Background technique [0002] Some existing network devices implement packet forwarding based on a MAC (Media Access Control, Media Access Control) forwarding table. After these network devices receive the message sent by the device, they can search the MAC forwarding table in the MAC forwarding table for the MAC forwarding table item that matches the destination MAC address carried in the message. , forward the packet according to the found MAC forwarding entry; when there is no MAC forwarding entry matching the destination MAC address, broadcast the packet. That is, regardless of whether there is a MAC forwarding entry that matches the destination MAC address, the network device will perform pass processing on the received packet. [0003] However, because there may be attacking devices in the network, that is, the...
