Embodiment Construction

[0094] 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.

[0095] figure 1 It is a schematic diagram of the OAM configuration process between PE devices in the VPN network. PE1 10 represents the source-end operator edge router PE, and PE211 indicates the sink-end operator edge router PE. PE211 issues labels to PE110; PE110 uses these labels to encapsulate packets and forwards data streams to PE211. The direction in which OAM performs detection is the same as the direction in which data flows are forwarded. In this s...

Abstract

An embodiment of the invention provides a method, a device and a system for OAM configuration. The method comprises the steps of configuring a source-side OAM entity for a source-side PE, and forbidding the source-side OAM entity to send an OAM message to the source-side PE; sending a first LSP Ping request message carried with source-side OAM entity configuration information to a sink-side PE; receiving a first LSP Ping response message carried with sink-side OAM entity configuration information and sent by the sink-side PE, and enabling an energy-side OAM entity to send the OAM message the sink-side PE when the sink-side OAM entity configuration information is matched with the source-side OAM entity configuration information. The embodiment of the invention further provides the source-side PE, the sink-side PE and the OAM configuration system. By adopting the technical scheme, the OAM configuration working amounts of the source-side and the sink-side are decreased, the source-side and the sink-side dynamically finish the OAM configuration by interacting the LSP Ping response messages, and errors arisen in manual configuration are avoided.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to an OAM configuration method, device and system. Background technique [0002] Perfect operation, management and maintenance (English full name is Operations, Administration and Maintenance, English abbreviation OAM) function is an important symbol of carrier-class network. It is extremely important for operators. OAM can reduce the operator's operational complexity and The operation and maintenance cost can enhance the availability of the operator's network, and can also help the operator's network verify the SLA (Service-Level Agreement) signed with the user. [0003] The OAM mechanism mainly includes three aspects: Fault Management, Performance Monitoring and Protection Switching. Among them, fault management can be divided into four aspects: fault detection (Fault Detection), fault verification (Fault Verification), fault localization (Fault Localization) and faul...
