Method and device for establishing multi-protocol label switching (MPLS) protection ring

Abstract

The invention discloses a method for establishing a multi-protocol label switching (MPLS) protection ring, comprising the following steps of: receiving a first network element selection instruction of a user, selecting a first network element according to the first network element selection instruction of the user, and obtaining an MPLS protection ring containing the first network element according to the selected first network element; displaying the obtained MPLS protection ring containing the first network element; receiving an MPLS protection ring selection instruction of the user, selecting an MPLS protection ring containing the first network element according to the MPLS protection ring selection instruction of the user and prominently displaying the same; and numbering the network elements in the prominently-displayed MPLS protection ring containing the first network element. The method for establishing an MPLS protection ring provided by the embodiment of the invention can increase the success rate and efficiency of establishing the MPLS protection ring.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular to a method and device for creating a Multiprotocol Label Switching (MPLS, Multiprotocol Label Switching) protection ring. Background technique [0002] Packet Transport Network (PTN, Packet Transport Network) utilizes Pseudo Wire Emulation Edge-to-Edge (PWE3, Pseudo Wire Emulation Edge-to-Edge) technology to realize connection-oriented service bearing, and adopts multi-protocol label switching ( MPLS (Multiprotocol Label Switching) forwarding technology, combined with a complete operation, management and maintenance (OAM, Operation, Administration and Maintenance) protection switching mechanism, concentrates on packet transport network and synchronous digital transmission system (SDH, Synchronous Digital Hierarchy) transport network The advantages of this technology make the PTN network also have simple and efficient network-level protection, and realize telecom-...

AI Technical Summary

Problems solved by technology

[0004] The inventors of the present invention have found that the following problems exist in the MPLS protection ring creation process in the prior art: (1) all network elements are manually selected, and the user must clearly understand which network elements the MPLS protection ring passes through, otherwise, the MPLS protection ring cannot created successfully

(2) The order of network element selection must be consistent with the physical connection order of network elements, and must be selected in a clockwise or counterclockwise direction, otherwise, the MPLS protection ring cannot be created successfully

(3) Creating an MPLS protection ring requires very high skills for users. Users need to understand the principles of MPLS protection rings. Otherwise, it will be difficult for users to successfully create

(4) The efficiency of creating MPLS protection rings in the prior art is low, the process of selecting network elements is very cumbersome and error-prone (wrong network elements are selected or the order is chaotic), and it is difficult for users to find the error point after making an error, which affects user experience
