Problems solved by technology

At present, after an alarm is reported and a fault is reported, manual loopback of each hop on the LSP path is adopted. The operation is very cumbersome, the efficiency of service detection and fault location is low, and the maintenance personnel have high requirements for troubleshooting. , the maintenance cost of the PTN / IPRAN network will also increase

Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] see figure 1 As shown, the embodiment of the present invention provides a method for fast detection of LSP based on loopback in a PTN / IPRAN network management, comprising the following steps:

[0035] S1. Preparatory work: The system adopts the end-to-end configuration method to configure the LSP to be detected, the service configuration carried on the LSP, and the LSP active OAM parameters, and send all the configured parameters to the network PTN / IPRAN equipment; when LSP needs to be During detection and fault location, parameters of LB (Loop Back, loopback) in LSP on-demand OAM must also be configured.

[0036] Table 1. LSP active OAM parameters and LSP on-demand OAM parameter list of LB

[0037]

[0038]

[0039] As shown in Table 1, LSP active OAM parameters include CV (Connectivity Verification, connectivity verif...

Abstract

The invention discloses a method and system for achieving LSP quick detection based on loopback in PTN / IPRAN management, and relates to the field of PIN / IPRAN maintenance. The method comprises the following steps that an LSP to be detected, configuration of services borne by the LSP and OAM parameters related to an LSP layer are completed through system configuration; whether communication between LSP source and host is interrupted or not is detected, if the communication is unobstructed, it shows that the LSP is normal, and detection is stopped; if the communication is interrupted, LB hop-by-hop detection between LSP nodes is automatically carried out, whether the hops of the LSP and the source and host are unobstructed or not is judged, failure nodes on the LSP are located and recorded, failure points on an LSP path are displayed through graphical interfaces according to a recorded LB result, and an electronic failure treatment work order is generated. According to the method and system, failure detection and failure locating efficiency can be effectively improved, the efficiency of maintenance management and the automation level can be improved, the requirement for the failure troubleshooting level of maintenance personnel is lowered, and network maintenance cost is lowered.

Description

technical field [0001] The invention relates to the field of PTN / IPRAN end-to-end network maintenance, in particular to a method and system for fast detection of LSP based on loopback in PTN / IPRAN network management. Background technique [0002] With the wide application of PTN (Packet Transport Network, packet transport network) / IPRAN (IP Radio Access Network, IP radio access network) network in various operators. The network maintenance personnel of various operators put forward higher requirements for OAM (Operation Administration and Maintenance, operation, management, maintenance) management, especially how to quickly perform service provisioning detection and fault location, which requires LSP (Label Switched Path, label switch paths) for quick and intuitive management of turn-up detection and fault location. At present, after an alarm is reported and a fault is reported, manual loopback of each hop on the LSP path is adopted. The operation is very cumbersome, the ef...
