Method for rapid convergence of layer 2 multicast of Ethernet and Ethernet system

Abstract

The invention relates to a method for the rapid convergence of layer 2 multicast of the Ethernet and an Ethernet system. The method comprises that: a node determines the existence of a user on a failing port or blocked port, and determines that the user may be offline due to a failure or blocking; the node constructs a leave message of a group with the user, and sets the maximum response time of the leave message to be a preset value; a querier receives the leave message, judges the maximum response time is the preset value according to the leave message, and transmits a query message to all non-multicast routing ports of the querier; and the downstream equipment of the querier receives the query message, and finishes switching multicast traffic in response to the query message. By the method and the Ethernet system, the problem that a multicast service cannot be rapidly switched when link topology is changed is solved, and the reliability and stability of the multicast service are ensured.

Description

technical field [0001] The invention relates to the technical field of Ethernet, in particular to a method for rapid convergence of Ethernet Layer 2 multicast and an Ethernet system. Background technique [0002] In recent years, with the rapid popularization and promotion of the Internet, the application of multicast technology and ring network technology in the market has become more and more extensive. [0003] Multicast technology refers to a network communication technology in which a single sender corresponds to multiple receivers. It realizes point-to-multipoint high-speed transmission in IP (Internet Protocol) network communication, which can effectively save network bandwidth and reduce Network load, widely used in many aspects such as real-time data transmission, multimedia conference, data copy, game and simulation. [0004] Ring network technology is a real-time link backup technology, which provides a guarantee for the reliable transmission of business data, an...
