Problems solved by technology

[0005] It can be seen that if the network attacker uses the host to pass the access authentication, the router will still be attacked by the IGMP attack initiated by the network attacker using the host, thereby affecting the performance of the multicast network.

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0048] The embodiment of the present application provides a method and device for processing messages, which can be applied to a router in a multicast network. The router is provided with a port for connecting to a host, and the port for connecting to a host can be one or Multiple. see figure 1 , figure 1 The framework diagram of a networking provided by the embodiment of this application is a possible application scenario. The networking includes: router A, router B, switch A, swi...

Abstract

The embodiment of the present application provides a method and device for processing messages, which can be applied to routers in multicast networks. The routers are provided with ports for connecting hosts to detect the message receiving rate of the port. If the message of the port If the receiving rate is greater than the preset first rate threshold, it is determined that the current packet processing method for this port is the first packet processing method, and the first rate threshold is determined according to the preset correspondence between the connection type and the rate threshold. The rate threshold corresponding to the connection type of the port. When the port is in the first packet processing mode, discard the packets received through the port. Based on the above processing, the router can detect the packet reception rate of each port, and when the packet reception rate of a certain port is greater than the first rate threshold, discard the packets received through the port, thereby reducing the impact of IGMP attacks on the multicast network. performance impact.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a method and device for processing messages. Background technique [0002] Currently, in a multicast network, a host and a router maintain the membership relationship of a multicast group through an Internet Group Management Protocol (IGMP). The host can send an IGMP message (including an IGMP report message and an IGMP leave message) to the router, and the router can maintain the membership of the multicast group corresponding to the IGMP message according to the IGMP message. [0003] According to the IGMP report message, the router can determine the multicast group to which the host belongs, record that the multicast group currently contains members of the multicast group, and then forward the data packets sent to the multicast group to the multicast group; According to the IGMP leave message, the router can determine the multicast group that the host leaves, a...
