A DEVICE AND METHOD FOR IMPLEMENTING A CHANNEL OF SIGNALING COMMUNICATION NETWORK AND MANAGEMENT COMMUNICATION NETWORK

WIPO Patent Application WO/2009/074002

A1

A device and method for implementing a channel of signaling communication and management communication network are provided. The device comprises a network element control single board and at least one optical interface single board connected by Ethernet interface; the network element control single board is used to accomplish routing protocol, process or forward Ethernet message; the optical interface single board is used to insert or extract overhead of the optical signal and adapt and forward optical signal message with different formats. By using Ethernet technique, the ECC network management signaling of the optical transport network element device and the signaling of ASON can use a common data bus, by the third layer switch unit implemented by hardware, the pressure of the CPU unit can be reduced; SCN and MCN channel with large capacity and high speed can be realized in transport device at the lowest cost, the channel is not only compatible with the original IP over PPP external interface, but also provides large bandwidth, low CPU load and the bus multiplexing function, thereby providing a support of stronger processing capacity for implementing the intelligence of optical transport device.
