摘要： A system and method for performing rate adaptation of sub1G packet-oriented client signals for transmission over a Metro Transport Network (MTN) by forming a 64B/66B-encoded client signal from individual client packets of the sub1G packet-oriented client signal and the idle blocks within an inter-packet gap (IPG), inserting thread operations, administration and maintenance (ThOAM) overhead to generate a 64B/66B-encoded client thread signal, performing an idle mapping procedure (IMP) to generate a rate adapted 64B/66B-encoded client thread signal, defining a plurality of pseudo-Ethernet packets in an MTN path, defining a thread channel within the plurality of pseudo-Ethernet packets and mapping the rate adapted 64B/66B-encoded client thread signal into the defined thread channel within the plurality of pseudo-Ethernet packets to generate an MTN path signal for transmission to an intermediate node or a sink mode.

摘要： 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.

摘要： A method and apparatus in which a data stream generated by a previous network node, a cumulative phase offset report (CPOR) and a client rate report (CRR) are received. A counter accumulating a PHY-scaled stream clock (IPSCk) is sampled at a nominal sampling period (Tps) to obtain a cumulative PHY-scaled count (CPSC). A PHY-scaled stream phase offset (PSPO) is calculated that indicates phase difference between a PHY-scaled stream nominal bit count (LPSD) and an incoming PHY-scaled count delta (IPSD), where IPSD indicates CPSC increment between successive CPSC samples. The data stream is demultiplexed to obtain CBR carrier streams that include a previous network node CPOR (CPOR-P) and a previous network node CPO (CPO-P). A CPO is calculated that is a function of CPO-P and the PSPO. CPO-P is replaced with the calculated CPO. The CBR carrier streams are multiplexed into intermediate-network-node data streams that are transmitted from the intermediate-network-node.

摘要： 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.

摘要： A method and apparatus in which a data stream is received that includes constant bit rate (CBR) carrier streams, at least one of which comprises frames, a cumulative phase offset report (CPOR) and a client rate report (CRR). A counter accumulating a PHY-scaled stream clock (IPSCk) is sampled at a nominal sampling period (Tps) to obtain a cumulative PHY-scaled count (CPSC). A PHY-scaled stream phase offset (PSPO) is calculated that indicates phase difference between PHY-scaled stream nominal bit count (LPSD) and an incoming PHY-scaled count delta (IPSD). The data stream is demultiplexed to obtain CBR carrier streams. Respective CBR carrier streams include a previous network node CPOR (CPOR-P) and a previous network node CPO (CPO-P). A CPO is calculated that is a function of CPO-P and PSPO. CPO-P is replaced with the calculated CPO. The CBR carrier streams are multiplexed into intermediate-network-node data streams that are transmitted from the intermediate-network-node.
