Embodiment Construction

[0028] FIG. 1 is a schematic diagram of the Ethernet ring protection protocol ERP. The Ethernet nodes NE1 to NE7 in Figure 1 form a physical Ethernet ring. The above physical Ethernet ring can contain multiple logical domains, and each domain contains a working link. and a protection link. For example, in the domain shown in Figure 1, Ethernet nodes RM A, NE2, NE3, NE4, and NE5 form a working link, as shown by the solid line in Figure 1; while NE1, NE7, and NE6 form a protection link. link, as shown by the dotted line in Figure 1. A node in this domain is designated as Redundancy Manager (RedundancyManager) RM A. Other nodes on the Ethernet ring are designated as common switching nodes.

[0029] Usually a multicast source (Multicast Source) sends service information to nodes on a domain, and there are usually multiple virtual local area networks (Virtual Local Area Network; VLAN) in a domain, and each virtual local area network usually contains multiple multicast Multicast...

Abstract

The invention discloses a protection method of ethernet network circulation circuit, said ethernet network circulation circuit includes at least one ethernet network nodes, and at least one region, each of regions includes at least one work chains and at least one protection chains, said region includes at least one redundancy managers, every work node of said work chain informs other ethernet network nodes the multiple broadcasting information and updates said multiple broadcasting information table based on said multiple broadcasting information. The invention also discloses a protection system of ethernet network circulation circuit. Adopting the invention can shorten the resuming time of fault f dynamic multiple broadcasting operation from second to millisecond, and shortens the protection time.

Description

technical field [0001] The invention relates to a method for protecting an Ethernet ring, in particular to a method for protecting an Ethernet ring under a multicast service, and a protection system for an Ethernet ring corresponding to the method. Background technique [0002] At present, the application of Ethernet (Ethernet) has covered all aspects of the access network, the metropolitan area network and even the backbone network. However, with the continuous development of broadband data networks, the original Ethernet-based metropolitan area system is facing great challenges. The existing network architecture cannot provide carrier-level service protection means, and for In the event of a network interruption, it must be able to provide service protection and recovery through reliable measures. From the point of view of the existing network technology, adopting the structure based on the Ethernet ring network can provide effective protection for the user's business. ...
