In-band management networking method for GM equipment

Abstract

The invention discloses an in-band management networking method for GM equipment. A service interface and a management interface of the GM equipment are logically fused into a physical interface; a PTP service message and a network management message are sent to OTN equipment through the same physical interface; the two messages are identified at the side of the OTN equipment; the PTP service message is processed and sent according to PTP protocol standards; the network management message is sent to a central network management system; the network management message is coded according to the standard UDP protocol format; and thus, a set of central network manager can simultaneously perform network element management of the OTN equipment and the GM equipment. According to the in-band management networking method for the GM equipment disclosed by the invention, the service interface and the management interface of the GM equipment are logically fused into the physical interface; therefore, the fact that a set of central network manager can simultaneously perform network element management of the OTN equipment and the GM equipment can be effectively realized; and thus, the operating cost is obviously reduced.

Description

Technical field [0001] The invention belongs to the field of communication technology, and relates to a networking method, in particular a GM equipment in-band management networking method. Background technique [0002] The PTP GrandMaster device (GM device for short) serves as the time source of the entire OTN transmission network, and the external physical interface is generally divided into a service interface and a network management interface. The business interface is connected to the downstream transmission network to provide timing services. The network management interface is connected to the central network management system, and each GM device is managed by the central network management station. Such as figure 1 Shown. [0003] At the network element management level, such as figure 2 Shown: Usually GM equipment and OTN transmission equipment each use their own central network management system to manage their own network elements. [0004] This method in the prior ar...

AI Technical Summary

Problems solved by technology

[0005] GM equipment and OTN equipment are usually used at the same time, but GM equipment and OTN equipment are usually developed and produced by different manufacturers, so each uses its own central network management system. For operators, two sets of centers need to be operated, maintained, and managed at the same time. Network management system, increased operating costs
