Method of accommodating signals, frame generation apparatus, frame reception apparatus, and transmission system

摘要

For a frame comprising a payload region in which a client signal is to be accommodated, and an overhead region accommodation location information indicating a location where the client signal is to be accommodated, the frame being able to be processed as an m (m is an integer equal to or greater than 2)-byte cycle multiframe, the location information for the frame is defined as an m×n (n is an integer equal to or greater than 2)-byte cycle multiframe; using the location information defined as the multiframe, the location where the client signal is to be accommodated in the payload region is defined; and the client signal is accommodated in the payload region, based on the defined location where the client signal is to be accommodated.

1. A method of accommodating signals in a frame generation apparatus that generates a first frame, the first frame comprising a payload region in which a client signal is to be accommodated, and an overhead region accommodating first location information indicating a location where the client signal is to be accommodated, the first frame being able to be processed as an m (m is an integer equal to or greater than 2) -byte cycle multiframe, the method comprising:
defining the first location information as a multiframe including n (n is an integer equal to or greater than 2) sub-multiframes each having m-byte cycle; defining, using the first location information defined as the multiframe, the location where the client signal is to be accommodated in the payload region; and accommodating the client signal in the payload region, based on the defined location where the client signal is to be accommodated, wherein the first frame is accommodated in at least one of a plurality of slot regions of a second frame, the second frame including the plurality of slot regions and a second location information having a size of m bytes, each of the plurality of slot regions having a predetermined size, the second location information including type information indicating a type of each of the plurality of slot regions, and the type information indicates whether at least a part of the first frame is accommodated in each of the plurality of slot regions, wherein the first frame is an optical channel payload unit (OPU) frame and the second frame is an optical channel data unit (ODU) frame.
