Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0030] According to the embodiment of the present invention, the multi-protocol label switching path APS protection management method, equipment and system need to independently configure two MPLS-TE tunnels, and independently enable OAM and bind APS protection groups for the implementation of APS protection for MPLS-TE tunnels in the prior art. , has the disadvantages of complex configuration, inflexibility, and inseparable protection group paths. By establishing the active and standby LSPs corresponding to the two end-to-end paths of the MPLS-TE tunnel respectively, as an APS protection group, enable the active LSP and the OAM function of the backup LSP. This simplifies the configuration of the APS protection ...

Abstract

The invention relates to the technical field of network communication, and discloses multiprotocol label-switched path APS protection and management method, equipment and system, wherein the method comprises the following steps of: establishing an MPLS-TE (Multiprotocol Label Switching-Traffic Engineering) tunnel; computing to obtain the two end-to-end paths of the MPLS-TE tunnel; and respectively establishing a main LSP (Layered Service Provider) to one path in the two paths and a spare LSP corresponding to the other path in the two paths to be used as an automatic protection switching protection group, and enabling the OAM (Operation, Administration and Maintenance) functions of the main LSP and the spare LSP. The invention can be utilized for simplifying the configuration for the APS protection of the MPLS-TE tunnel and effectively realizing the automatic protection switching of the MPLS-TE tunnel.

Description

technical field [0001] The invention relates to network communication technology, in particular to a multi-protocol label switching path APS protection management method, equipment and system. Background technique [0002] MPLS (MultiProtocol Label Switching, Multi-Protocol Label Switching) has become an important technology in the communication network, and has been widely used in the Internet and many typical operator networks. ), MPLS VPN (Virtual Private Network, virtual private network) and MPLS QoS (Quality of Service, quality of service) are the most important and common. [0003] MPLS-TE is a technology based on traffic engineering database and constraint routing calculation, aiming to improve resource utilization and service quality of a specific network. This goal is achieved through appropriate route selection, route optimization, and various flow management and control methods for various business flows with different QoS requirements and constraints, so that va...
