Title:
METHOD FOR TRANSPORTING CLIENT SIGNAL IN OPTICAL TRANSPORT NETWORK, AND TRANSPORT DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/001280
Kind Code:
A1
Abstract:
Disclosed are a method for transporting a client signal in an optical transport network, and an optical transport network device. The method comprises: dividing payloads of an optical payload unit signal into m time slots with a first granularity; dividing a time slot with the first granularity among the m time slots with the first granularity into n time slots with a second granularity, wherein the rate of the time slots with the first granularity is n times the rate of the time slots with the second granularity, m is a positive integer, and n is a positive integer greater than 1; mapping a first client signal into the payload where one or more time slots with the second granularity among the n time slots with the second granularity are located; adding an overhead of a time slot with the first granularity and an overhead of a time slot with the second granularity to the optical payload unit signal to generate an optical data unit signal; and sending the optical data unit signal. By means of the embodiments of the present invention, the bandwidth transport efficiency is improved.
