Embodiment Construction

[0024] Various preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] The device for delaying the channel payload data of optical synchronous digital transmission network of the present invention, its core idea is: after carrying out channel demultiplexing to STM-1, STM-4, STM-16 and STM-64 etc., will separate out The payload and payload indication of the time channel are stored in the first-in-first-out FIFO for channel storage. When the write address of the FIFO is equal to the delay byte, that is, the delay time, read the payload and payload of the delay channel from the FIFO Instructions, and then perform channel multiplexing with other undelayed channels to form new STM-1, STM-4, STM-16 and STM-64, etc.

[0026] A device for delaying the payload data of an optical synchronous digital transport network channel according to the present invention, its realization schematic diagram is as follows...

Abstract

The invention relates to a method for delaying the load data of light synchronous digit transmission network channel, wherein it comprises: a channel de-multiplex module; a channel storage module with synchronous FIFO module, write point control module and read point control module, while the channel storage module is used to store and read the channel load and load instruct of delay channel based on the delay distribution information; a channel multiplex module for multiplexing the non-delay part and the delay channel, based on SDH frame structure multiplex projection theory, to generate new STM-1, STM-4, STM-16, or STM-64 frame of delay channel. The invention supplies needed channel delay data for designing transmission device, to improve the design property of transmission device.

Description

technical field [0001] The invention relates to a device for delaying optical synchronous digital transport network (SDH) channel payload data, in particular to a technology for virtual concatenation delay compensation processing and channel delay processing in the SDH transmission system in the communication field. Background technique [0002] The delay in the prior art refers to the delay in digital signal transmission, that is, it always takes a certain amount of time for a signal to be transmitted from one place to another. There are three main reasons for the delay, including the delay caused by the transmission system, the delay caused by the network digital equipment, and the delay caused by the introduction of SDH equipment. Since the delay of the photoelectric signal in the medium propagation is related to the refractive index of the transmission medium, the existence of the refractive index of the medium will cause a certain delay in the transmission signal, which...
