摘要： The present disclosure provides systems and methods for real-time, in-service latency measurements over optical links that may be further integrated within various optical control planes. The present invention may utilize minimal unused overhead to calculate latency of an optical line through a transport network. The present invention utilizes timers at two end-point nodes associated with the optical line, and includes a mechanism to filter out frame skew between the nodes. Advantageously, the present invention provides a highly accurate latency measurement that may calculate latency on links as small as one meter, an in-service algorithm operable without network impact, and may be integrated with an optical control plane to automatically provide administrative weight variables associated with link costs.

摘要： The present disclosure provides a structured, pipelined large time-space switch and method of operation resolving interconnect complexity. The time-space switch results in an interconnect complexity that does not grow as the spatial dimension is increased and results in a reduction of long high fan-out nets, a quicker layout, and improved clock speed. With respect to time-space switch fabric implementation, the present invention improves the maximum clock frequency of the switch fabric, and improves integrated circuit layout time by eliminating long high fan-out nets. Certain high-speed large switch fabrics may not be realizable without this implementation, and it significantly reduces implementation time (and cost). The present invention may include link encoding of switch frames by mapping 8B10B control characters into an 64B65B format (similar to Generic Framing Protocol-Transparent (GFP-T)), wrapping 32 65B encoded words with an 11-bit error correcting code, and scrambling the frame with a frame synchronous scrambler.

摘要： The present disclosure provides systems and methods for inserting pseudo-noise in a data stream based on an unacceptable input data sequence in an optical network thereby preventing unnecessary loss of frame in SONET/SDH or Optical Transport Network (OTN) systems. The present disclosure includes a SONET/SDH or OTN framer, a transceiver, and a method for detecting an unacceptable data sequence or pattern and inserting a keep-alive or pseudo-noise sequence in the data sequence to maintaining framing on subsequent network elements, framers, transceivers, etc. For example, the present invention, upon receiving an unacceptable pattern of zeros or low ones density caused by a loss of signal condition or the like, may insert a pseudorandom noise pattern into the transmitted frame. This allows the downstream network element to continue a frame lock on the incoming signal, and thus keep the frame overhead and data communications channels from being lost.

摘要： An Optical channel Data Unit flex (ODUflex) resizing method, node, and network include determining that the ODUflex needs resizing, wherein the ODUflex is configured in the network on a current path between the node and a second node in the network; when the resizing is a decrease, reducing a size of the ODUflex by i) a resize decrease operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation; and, when the resizing is an increase, increasing a size of the ODUflex by i) a resize increase operation using a control plane or ii) a Link Aggregation Group and Make-Before-Break operation. The method provides hitless resizing without using ITU Recommendation G.7044/Y.1347 (10/11) and can perform the reducing or the increasing changing bandwidth of the ODUflex by approximately 100 G in less than a second.
