Embodiment Construction

[0047] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0048]The solution of the embodiment of the present invention is mainly: by acquiring the fault alarm information of the OTN optical channel of the optical transport network, and determining the corresponding OTU service frame of the optical conversion unit according to the fault alarm information; Perform settings to obtain the set target service frame; according to the target service frame, the alarm in the optical channel domain of the OTU service is alarmed and isolated; it can prevent the OTN optical channel protection deadlock, fully protect the existing investment, and can smoothly expand the new network connection. It has strong compatibility, guarantees the stability of important dedicated lines, and fills the gap in the industry for the use of optical channel protection for OTU services. It only needs t...

Abstract

The invention discloses a method, device, equipment and storage medium for preventing OTN optical channel protection deadlock. The method obtains fault alarm information of an OTN optical channel of an optical transmission network, and determines a corresponding optical conversion unit according to the fault alarm information OTU service frame; set the reserved byte RES in the service frame to obtain the set target service frame; according to the target service frame, alarm and isolate the alarm in the optical channel domain of the OTU service; can prevent OTN optical channel protection Deadlock, fully protects existing investment and can smoothly expand new network access, strong compatibility, guarantees the stability of important private lines, and fills the gap in the industry for the use of optical channel protection for OTU services. Only the software level is required. As well as optimization at the business level, no hardware changes are involved, and no additional investment is required, which saves costs while solving the hidden dangers of transmission security.

Description

technical field [0001] The invention relates to the field of optical transmission, in particular to a method, device, equipment and storage medium for preventing OTN optical channel protection deadlock. Background technique [0002] Packet Optical Transport Network (POTN) integrates Optical Transport Network (OTN) and packet switching technology, and fully supports Synchronous Optical Network (SONET) / Synchronous Digital Hierarchy (SDH) 、Automatically Switched Optical Network (ASON) / Generalized Multiprotocol Label Switching (GMPLS) control plane, with wavelength division multiplexing (WDM) transmission function in the core / backbone network and wavelength-level crossover capability. [0003] Optical Channel Protection (OCP), as a type of OTN photoelectric protection, is an important guarantee for the transmission stability of the OTN system. Currently, optical channel protection is mainly divided into optical channel protection and optical line protection. [0004] The optic...
