Title:
SIGNAL TRANSMISSION METHOD, APPARATUS AND COMMUNICATION SYSTEM FOR OPTICAL TRANSPORT NETWORK
Document Type and Number:
WIPO Patent Application WO/2010/121520
Kind Code:
A1
Abstract:
A signal transmission method, apparatus and communication system for optical transport network are provided by the embodiments of the invention. Said method comprises: obtaining client signals (210); mapping said client signals into an optical channel data unit xt (220); dividing said optical channel data unit xt into x independent optical channel data units t (230); multiplexing said x optical channel data units t into time slots of an optical channel data unit k, and transmitting said optical channel data unit k to target nodes (240). By dividing client signals into several blocks, the technical solutions provided by the embodiments of the invention use some time slots of an optical channel data unit k to bear the divided client signals, and can flexibly adjust bandwidth occupied by the client signals with smaller bandwidth granularity, and can improve utilization of bandwidth resource relatively.
