Embodiment Construction

[0036] The preferred embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] A device for realizing the sorting of multi-virtual concatenation group members at least includes a queue sorting module, a sorting circuit module and a calling module.

[0038] The queue sorting module is used to determine the sorting queues of all VCGs that arrive according to the order of the arrival time of the latest arriving members in each VCG;

[0039] The arrival time of the latest arriving member of the VCG refers to: comparing the arrival time of the H4 or K4 byte in the last subframe of each multiframe corresponding to each member of the VCG (that is, the writing direction multiframe of the VCG), the latest arriving subframe The arrival time of the H4 or K4 byte is the arrival time of the latest member of the VCG.

[0040] A sorting circuit module, configured to sequentially sort member...

Abstract

The invention discloses a method and a device for sequencing multiple virtual concatenation group (VCG) members, which relate to virtual concatenation technology in the field of optical communication. The method comprises the following steps of: determining the sequencing queue of all arrived VCGs according to the sequence of arrival time of a latest arrived member in each VCG and performing member sequencing on each VCG in turn in an arrangement queue; and when an allowed time interval between a set sequence and a called sequencing result is reached, calling a member sequencing result of each VCG. In the technical scheme of the invention, the member sequencing of multiple VCGs can be realized effectively through a sequencing circuit and logic resource consumption is reduced greatly.

Description

technical field [0001] The invention relates to virtual concatenation technology in the field of optical communication. In particular, it relates to the implementation of member ordering in the case of multiple VCGs in LCAS processing. Background technique [0002] When a Synchronous Digital Hierarchy (SDH, Synchronous Digital Hierarchy) system carries services, different levels of Synchronous Transfer Modules (STM, Synchronous Transfer Module) correspond to different levels of transmission rates, such as figure 1 shown. Some transmitted information payloads do not completely match the standard rates of SDH's various virtual containers, such as image coding signals and IP router signals, etc., resulting in cascade technology. The bandwidth of the transmission service can be dynamically adjusted by using the cascading technology, which includes adjacent cascading and virtual cascading. [0003] Adjacent concatenation (Contiguous Concatenation) is the frame structure of the...
