Title:
A DEVICE AND METHOD FOR IMPLEMENTING A CHANNEL OF SIGNALING COMMUNICATION NETWORK AND MANAGEMENT COMMUNICATION NETWORK
Document Type and Number:
WIPO Patent Application WO/2009/074002
Kind Code:
A1
Abstract:
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.
