US 9,313,118 B2 · Method and apparatus for intercepting multicast protocol packet and switch

Abstract

The present disclosure provides a method and an apparatus for intercepting a multicast protocol packet and a switch. The method for intercepting a multicast protocol packet includes: acquiring multicast work information of a router; acquiring a multicast protocol parameter of the switch according to the multicast work information of the router, where the multicast protocol parameter includes an interval of sending general query packets, a robustness variable, and a query response interval; acquiring port aging time of the switch according to the multicast protocol parameter of the switch; and aging a port if no multicast protocol packet is received on the port within the port aging time. The present disclosure further provides a corresponding apparatus and a switch including the apparatus.

Dependent claims

A method for intercepting a multicast protocol packet, comprising:

acquiring, by a switch in a computer network, multicast work information of a router, wherein the multicast work information comprises an interval of receiving general query packets, a number of group-specific query packets that are received after the switch forwards a host leave packet to the router, and a maximum response time set for a multicast group member host;
acquiring, by the switch, multicast protocol parameters of the switch according to the multicast work information of the router, wherein the multicast protocol parameters comprise an interval of sending general query packets, a robustness variable, and a query response interval;
acquiring, by the switch, a port aging time of the switch according to the multicast protocol parameters of the switch;
and
aging, by the switch, a port if no multicast protocol packet is received on the port within the port aging time.

A switch, comprising:

a processor, multiple ports,
and, wherein the processor is configured to;
acquire multicast work information of a router, wherein the multicast work information comprises an interval of receiving general query packets, a number of group-specific query packets that are received after the switch forwards a host leave packet to the router, and a maximum response time set for a multicast group member host;
acquire multicast protocol parameters of the switch according to the multicast work information of the router, wherein the multicast protocol parameters comprise an interval of sending general query packets, a robustness variable, and a query response interval;
acquire a port aging time of the switch according to the multicast protocol parameters of the switch;
and age a port of the multiple ports if no multicast protocol packet is received on port within the port aging time.
