Embodiment Construction

[0045] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, but not to limit the present invention.

[0046] figure 1 is a flow chart of a service path restoration method provided by an embodiment of the present invention, such as figure 1 shown, including:

[0047] Step S101: Find the BRAS on the service path of the set-top box according to the public network IP address of the set-top box;

[0048] Step S102: Use the set-top box public network IP address and the unicast routing virtual route to forward the VRF, respectively obtain the outbound interface of the aggregation switch corresponding to the BRAS on the service path, and the PTN inbound interface connected to the aggregation switch on the service path. The static tunnel and the optical line terminal OLT and t...

Abstract

The invention discloses a service path restoration method and device, and relates to the technical field of service path restoration. The method includes: finding a bandwidth remote access server BRAS on the service path of the set-top box according to the public network IP address of the set-top box; using the public network IP address of the set-top box and unicast routing virtual route forwarding VRF, respectively obtain the outbound interface of the aggregation switch corresponding to the BRAS on the service path, the static tunnel of the PTN inbound interface connected to the aggregation switch on the service path, and the optical line on the service path. Terminal OLT and Optical Network Unit ONU.

Description

technical field [0001] The present invention relates to the technical field of service path restoration, in particular to a service path restoration method and device. Background technique [0002] With the development of big video services, video services have increasingly become the basic services of operators, and their bearer requirements and operation and maintenance requirements are becoming more and more urgent. When the big video user experience is degraded, how to quickly delimit and locate the fault is one of the research topics of current telecom operators. [0003] Service path restoration is the core part of intelligent fault diagnosis in the end-to-end fault location system from the fixed network to the bearer network. When the experience of a user service is degraded and the fault needs to be delimited and located for the user service, the The complete path that the service passes through is described, and then the fault is checked segment by segment or one b...
