Abstract: A system and method for performing rate adaptation of constant bit rate (CBR) client data for transmission over a Metro Transport Network (MTN) by defining a plurality of pseudo-Ethernet packets at a source node, assembling a plurality of Generic Mapping Procedure (GMP) frames by mapping a plurality of blocks from a stream of encoded blocks of CBR client data, a plurality of pad blocks, and GMP overhead into consecutive pseudo-Ethernet packets of the plurality of pseudo- Ethernet packets, inserting a fixed number of idle blocks between one or more of the consecutive pseudo-Ethernet packets and inserting an MTN path overhead (POH) frame that is aligned to the plurality of GMP frames to generate a plurality of rate adapted GMP frames for transmission over the MTN to an intermediate node or a sink node.

Abstract: A method for inserting path overhead, POH, data blocks (60) and a Metro Transport Network ordered set, MOS, control block (62) into a data stream (68) in a source node of a 64B/66B-block communication link, the method comprising: generating a MOS control block (62) by assembling MOS control data into a 64B/66B block; generating K POH data blocks (60) by assembling POH data into K 64B/66B blocks; and inserting the MOS control block (62) and the K POH data blocks (62) into predetermined locations in the data stream in the 64B/66B-block communication link.

Abstract: A system and method for performing rate adaptation and multiplexing of constant bit rate (CBR) client data for transmission over a Metro Transport Network (MTN) by defining a plurality of plurality of generic mapping procedure (GMP) thread frames for a respective stream of two or more streams of 64B/66B-encoded blocks of CR client data, defining a plurality of pseudo-Ethernet packets, mapping the plurality of GMP thread frames into consecutive pseudo-Ethernet packets, assembling a stream of GMP multiplexing frames comprising the consecutive pseudo-Ethernet packets, inserting a fixed number of idle blocks between the consecutive pseudo-Ethernet packets of the stream of GMP multiplexing frames and inserting an MTN path overhead (POH) frame into the stream of GMP multiplexing frames to generate a stream of GMP multiplexing rate adapted frames.

Abstract: A method for extracting path overhead (POH) data blocks from a data stream in a 64B/66B-block communication link, the method includes receiving at a sink node a data stream in a 64B/66B-block communication link, detecting within the data stream at a PCS sublayer a micro-packet starting with an /S/ control block, including K POH data blocks, and ending with a /T/ control block, extracting the micro-packet from the data stream, and extracting the POH data blocks from the micro-packet.
