Embodiment Construction

[0016] Specific embodiments of the present invention will be given below to enable a better understanding of the principle and use of the method of the present invention.

[0017] First, there is a DCC digital control channel composed of D1, D2, D3 in the overhead bytes of SDH 155 transmission equipment. In each 155Mbps optical port, an embedded physical channel providing 192kbps transmission bandwidth can be used for transmission equipment. Network management information.

[0018] Secondly, in order to use the TCP / IP network protocol stack in the computer network, according to the 7-layer network communication layering concept in the communication standard, the high-level data link control (HDLC) of the link layer is encapsulated on the basis of the physical layer. control) protocol, which provides the second layer of protocol encapsulation.

[0019] Then, the IP network protocol is mapped on the basis of the high-level data link control layer HDLC, so that each SDH synchronous d...

Abstract

The method includes following steps: in 155Mbps transmission channel, the digital control channel of administration message transmitted in fiber link of SDH optical transmission equipment is mapped into IP data network; with router thought of IP data network, sets up the administration router through shortest path priority algorithm.

Description

Technical field [0001] The invention relates to a network management route setting method of a synchronized digital series optical transmission equipment (SDH), in particular to a 155Mbps SDH network management automatic route setting method applied to a network management system of optical transmission equipment. Background technique [0002] In the original traditional SDH optical transmission equipment network management system, the embedded control channel (ECC, embedded control channel) of the network management is a private protocol channel for point-to-point forwarding. After the network topology is determined, the network manager needs to have a deep understanding of the network topology. Then according to the network management personnel's understanding of the current network topology, manually configure the static route of the network management information, and the corresponding backup route, and specify the transmission channel of the network management information. T...
