摘要： A system and method are provided for mapping information into Synchronous Payload Envelopes (SPEs). The method provides information bytes at a nominal system clock-based data rate, which is about equal to a system clock, but may be adjusted. An external clock has a rate approximately equal to the system clock rate. The method generates SPEs with identically-positioned information bytes, regardless of differences between the system and external clock rates. The SPEs are combined with Transport Overhead (TOH) and transmitted as a message frame at the external clock rate. SPEs are generated maintaining the positions of the information bytes within each SPE, without pointer adjustments, despite differences between the system and external clock rates. Expressed another way, message frames are generated with payload and TOH sections, and the information bytes are located exclusively in the payload sections. As a result, constant pointer values (e.g., H1/H2 or V1/V2) are maintained for all the SPEs.

摘要： A system and method are presented for providing packet and time division multiplex (TDM) services in a data communication interface. The method accepts packets at a first rate over a packet interface, and transfers time-sensitive data in the packets as packet data units (PDUs) having a smaller number of bits than a packet and a second rate, faster than the first rate. The method transforms the PDUs into frames in a first TDM protocol. Typically, the PDUs are transformed into units having a smaller number of bits than the PDU and a third rate, faster than the second rate. Then, the TDM frames are transmitted over a line interface.

摘要： Various aspects provide for non-intrusively monitoring a network system. A multiplexing component is configured to receive a plurality of first encoded signals and generate a plurality of second encoded signals. The plurality of second encoded signals contain a different data rate and a different number of network lanes than the plurality of first encoded signals. A monitoring component is configured to identify a block location for repeating blocks and an alignment marker in each of the plurality of first encoded signals and/or the plurality of second encoded signals. The monitoring component can also be configured to identify one or more defects, identify error information and/or determine one or more skew values associated with the plurality of first encoded signals and/or the plurality of second encoded signals.

摘要： An Ethernet physical layer (PHY) module is provided with a method for transceiving between a 10GBASE-R client interface and a 100G attachment interface. On each of ten client interface logical lanes a 10GBASE-R signal is accepted. Each 10GBASE-R logical lane is demultiplexed into two 5 gigabit per second (Gbps) pseudo 100GBASE-R logical lanes, creating a total of twenty pseudo 100GBASE-R logical lanes. The pseudo 100GBASE-R logical lanes are arranged into n groups of 20/n pseudo 100GBASE-R logical lanes. Further, the pseudo 100GBASE-R logical lanes from each group are arranged into a 100G attachment logical lane. Finally, a 100G attachment logical lane is transmitted at an attachment interface on each of n physical lanes. In the reverse direction, each of n physical lanes accepts a 100G attachment logical lane at the attachment interface, and a de-aggregation process supplies a 10GBASE-R signal on each of ten client interface logical lanes.

摘要： A system and method are provided for deinterleaving differential inverse multiplexed (DIM) virtual channels in a 40G Ethernet receiver. The method accepts a 10.3125 gigabits per second (Gbps) (10G) Ethernet virtual channel with 64B/86B blocks, including periodic Lane Alignment Marker (LAM) blocks. The 10G virtual channel is deinterleaved into two 5.15625 Gbps (5G) virtual channels by: 1) deinterleaving consecutive blocks from the 10G virtual channel into the 5G virtual channels in an alternating order, and 2) reversing the order of deinterleaving in response to each detected LAM block. Then, the method supplies the 5G virtual channels (i.e. to a MAC module).

摘要： A system and method are provided for transporting a serial stream via a lower speed network using multiple parallel paths. At a transmitter, an optical or electromagnetic waveform is accepted representing a serial stream of digital information, and unbundled into n virtual information streams. Each virtual information stream is divided into a sequence of segments. Each segment is encapsulated, creating a sequence of packets by adding a start indicator to the beginning of each segment, and a terminate indicator to the end of each segment. Each packet is disinterleaved across m lanes and reinterleaved into n branches of framed data. Optical or electromagnetic waveforms representing the framed data are transmitted via n network branches. A receiver is also provided, which essentially reverses the above-described transmission method.
