Embodiment Construction

[0066] The invention provides a service recovery method, system and node equipment. In order to better understand the technical solutions of the present invention, the embodiments provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0067] see figure 2 , figure 2 It is a flow chart of the service restoration method provided by Embodiment 1 of the present invention.

[0068] In the embodiment of the present invention, if the current working path of the service fails, the service is restored. The service restoration method provided in Embodiment 1 of the present invention mainly includes the following steps:

[0069] B1. The node device receives a restoration path establishment request, and the restoration path establishment request carries the restoration path number corresponding to the service to be restored.

[0070] Specifically, the node device may receive a recovery path establishment request sent by an ...

Abstract

The embodiment of the invention discloses a service recovering method, belonging to the technical field of network communications. The method comprises the following steps: a node device receives a recovery path creation request, and the recovery path creation request carries the recovery path number corresponding to the service to be recovered; the node device acquires preset recovery path information corresponding to the service and the current usable time slot according to the recovery path number; the node device judges whether the node device is an end node of the service according to the recovery path information; if the node device is the end node of the service, the node device configures at least two recovery paths according to the current usable time slot, establishes the cross connection between the at least two recovery paths and sends the recovery path creation request to downstream nodes according to the recovery path information. The embodiment of the invention also discloses a service recovering system and a node device. Through the technical scheme provided by the embodiment of the invention, the service recovering speed can be quickened, and the system recourses are effectively saved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a service recovery method, system and node equipment. Background technique [0002] The optical transport network (Optical Transport Network, OTN) technology is a new generation of standardized digital transmission architecture, which is used to transmit correspondingly adapted payloads on the optical fiber transmission network. [0003] OTN defines the electrical layer encapsulation structure. Client signals need to be mapped to an overhead processing unit (Overhead Processing Unit, OPU). The OPU can be encapsulated into an optical channel data unit (Optical channel Data Unit, ODU). ODU can be encapsulated into an Optical Channel Transport Unit (Optical ChannelTransport Unit, OTU), or multiple low-order ODUs (low-rate ODUs) are multiplexed into one high-order ODU (high-speed ODU), and the high-order ODUs are repackaged To an OTU, the OTU can be transmitted using o...
