Duty and network management transparent transfer device and transparent transfer method on basis of ASON (automatically switched optical network)

Abstract

The invention discloses a duty and network management transparent transfer device and a transparent transfer method on the basis of an ASON (automatically switched optical network). The duty and network management transparent transfer device comprise an optical signal processing module, an SDH (synchronous digital hierarchy) overhead processing module and a DCC (data communication channel) overhead processing module. Second equipment of a factory B is further arranged between first equipment and third equipment of a factory A in the ASON and is different from equipment of the factory A, and the duty and network management transparent transfer device is connected with the first equipment, the second equipment and the third equipment by optical fibers. Optical signals of the first equipmentcan be transmitted into the optical signal processing module of the duty and network management transparent transfer device and can be converted into SDH data of electric signals, DCC overhead data inthe SDH data can be extracted in the SDH overhead processing module to obtain duty and network management information, the duty and network management information can be processed by the DCC overheadprocessing module, and overhead bytes can be retransmitted into overhead bus according to network management commands and related time sequences by the DCC overhead processing module. The DCC overhead data and business information are multiplexed and framed to obtain the SDH data, the SDN data can be converted into optical signals, and the optical signals can be transmitted to the third equipment. Duty and network management information can be transparently transferred between the first equipment and the third equipment of the factory A across the equipment of the factory B while normal business information communication is carried out.

Description

technical field [0001] The invention relates to the technical field of ASON, in particular to an ASON-based service and network management transparent transmission device and transparent transmission method. Background technique [0002] The Automatically Switched Optical Transport Network based on Synchronous Digital Hierarchy (SDH) and Optical Transport Network (OTN) is called ASON (Automatically Switched Optical Network). The main trunk line of traditional communication networks of this type is composed of ASON equipment from multiple manufacturers, such as ASON equipment from manufacturers such as Huawei, ZTE, and FiberHome in my country. In some special-purpose ASON networks, ASON devices from different manufacturers are often required to form a network together. Given the current level of technology and the openness of manufacturers' technologies, since the service interfaces of ASON equipment have the same standard, the ASON network composed of ASON equipment from di...

AI Technical Summary

Problems solved by technology

Because the equipment of factory B does not have the transparent transmission function of different service and network management information, the service and network management information transmitted by the equipment of factory A is discarded by the equipment of factory B, and another device of factory A cannot receive the service and network management information of the equipment of factory A
