Problems solved by technology

However, when using such ultra-high-rate transmission frames to transmit relatively low-rate services, it is necessary to use the existing low-rate transmission frames for multi-level multiplexing or multiplexing, which is more complicated and brings large delay
On the other hand, if high-rate transmission frames are directly used to carry client signals without multi-level multiplexing or multiplexing, there is a problem of low bandwidth utilization

Abstract

The embodiment of the invention provides a method for processing signals, a network device, and a system. The method comprises steps of: mapping a received first client signal into a first ODUflex; mapping the first ODUflex into an optical channel data branch unit Cn ODTUCn.X formed by X time slots, wherein the X is not an integer; and multiplexing the ODTUCn.X into an optical channel payload unit Cn ODTUCn. The method for processing signals provided by the embodiment of the invention is capable of increasing carrying efficiency when transferring small-granule service and is low in complexity.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a method, device and system for processing signals. Background technique [0002] Optical transport network (Optical transport network, OTN) as the core technology of the next generation transport network, including electrical layer and optical layer technical specifications, with rich operation, management and maintenance (OperationAdministrationandMaintenance, OAM) function, powerful serial connection monitoring (TandemConnectionMonitoring, TCM ) function and out-of-band Forward Error Correction (ForwardErrorCorrection, FEC) function, which can realize flexible scheduling and management of large-capacity services. [0003] As the rate of client signals continues to increase, frames used to transmit client signals in the OTN technology are also evolving. At present, the International Telecommunication Union is discussing a new transmission frame exceeding ...
