Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0037] The present invention proposes a method and equipment for transferring maintenance and management status in a packet transmission network aiming at the dividing point of maintenance and management domains, so as to solve the problem of maintenance and management dead ends when different maintenance and management mechanisms are bridged.

[0038] Such as figure 1 As shown, the present invention provides a transfer method for maintaining and managing stat...

Abstract

The invention discloses a mehtod and an equipment for maintaining transmission of administration state in packet transport network. The method comprises: one or a plurality of linkage groups with a unique identification are established on a connecting equipment which bestrides two or a plurality of maintenance administration domains, and each linkage group is provided with a driving side and a passive side on the connecting equipment; an operation administration maintenance (OAM) state of the maintenance administration domain corresponding to the driving side of the linkage group is monitored; and based on the obtained monitored result, the OAM state of the maintenance administration domain corresponding to the passive side of the linkage group is set. In the process of transmitting linear protections such as double return protection and the like in the network in groups, with the adoption of the method and the equipment both disclosed by the invention, operating paths and the OAM of protecting the paths can be efficiently linked.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and equipment for maintaining and managing state transmission in a packet transmission network. Background technique [0002] In the packet transmission network, the fault state of the link may change at any time. For the same maintenance domain or under the same maintenance system, the OAM (Operation Administration and Maintenance, operation, management, maintenance) state transmission technology is relatively mature, such as: The Ethernet link can be detected through the EFM (Ethernet in the First Mile, Ethernet in the first mile) mechanism, and the CFM (Connectivity Fault Management, connection fault management) mechanism and BFD (Bidirectional Forwarding Detection, bidirectional forwarding) can be used in a maintenance domain Detection) mechanism, Y.1731 and other mechanisms, but when different operating networks are bridged, and operators and customer...
