20110158255 | COMMUNICATION SYSTEM - Consistent with the present disclosure, a communication system is provided in which client data is received and provided in frames for transmission within the system. The frames include an overhead portion as well as locations that include the client data. The frames further include phase data or “virtual justifications” that periodically correct the difference between the phase represented by the data locations in the wrapper and the actual accumulated client phase. The phase data or virtual justifications, however, are decoupled from the data path. Therefore, without complicating the data path, the phase data may be sent more frequently and with finer granularity than the actual justifications. Virtual justifications or phase data are communicated via a “virtual justification control channel” which may part of the frame overhead. Moreover, there is no need for an actual “virtual justification opportunity” in the frame, because no data is actually sent in conjunction with the virtual justifications. | 06-30-2011 |
20110235438 | TEMPORAL ALIGNMENT OF DATA UNIT GROUPS IN A SWITCH - Consistent with the present disclosure, a plurality of FIFO buffers, for example, are provided in a switch, which also includes a switch fabric. Each of the plurality of FIFOs is pre-filled with data for a duration based on a skew or time difference between the time that a data unit group is supplied to its corresponding FIFO and a reference time. The reference time is the time, for example, after a delay period has lapsed following the leading edge of a synch signal, the timing of which is a known system parameter and is used to trigger switching in the switch fabric. Typically, the delay period may be equal to the latency (often, another known system parameter) or length of time required for the data unit to propagate from an input circuit, such as a line card of the switch or another switch, to the FIFO that receives the data unit. At the reference time, temporally aligned data unit groups may be read or output from each FIFO and supplied to the switch fabric. Since the timing of the output from the FIFOs is based on known system parameters, instead of the actual arrival of the slowest data unit group at its corresponding FIFO, time aligned data unit groups may be output regardless of whether the slowest data unit group is available. | 09-29-2011 |
20110235646 | METHOD AND APPARATUS FOR DETERMINING PROPAGATION DELAY IN A NETWORK - A propagation delay in the transmission of a frame from an initiator node to a peer node is determined by initially identifying a frame number and byte offset of a first incoming frame from the peer node at a time when the initiator node outputs a portion of a transmitted frame. The portion of the transmitted frame may be the first byte of a sub-frame within the transmitted frame. At the peer node, the frame number and byte offset of a second frame to be supplied to the initiator node is identified at a later time when the frame portion transmitted by the initiator node is received by the peer node, and such information is transmitted to the initiator node. Thus, since the frames output and received by the initiator node are typically of fixed duration, the frame number and byte offset of the incoming frame represent the time when the initiator node outputs the frame portion (a transmit time). In addition, the frame number and byte offset of the second frame represents the time at which the frame portion is received by the peer node (a receive time). Accordingly, by comparing the frame numbers and byte offsets of the first and second frames received from the peer node, a difference between transmit and receive times or propagation delay can be obtained. | 09-29-2011 |
