Abstract: Methods and systems for flexible-client, flexible-link optical transponders include electrical-to-optical transponders, which accept client data from a flow distributor, and a first multiplexing switch that connects modulated optical carriers from the transponders to line interfaces. The electrical-to-optical transponders each include a flexible optical transport unit (OTU) framer module that compresses multiple optical data units (ODUs) into a single ODU having a higher order than any of the input ODUs to form an optical transport network (OTN) frame. An electrical-to-optical modulator modulates OTN frames onto a carrier. The transponder includes a second multiplexing switch that accepts optical carriers from line interfaces and optical-to-electrical transponders that accept modulated optical carriers from the second multiplexing switch. Each optical-to-electrical transponder includes a photodetector to convert the modulated optical carriers to the electrical domain and a flexible OTU framer module that decompresses received ODUs in OTN frames into multiple ODUs to form a bit stream.

Abstract: A system and method (200) for network virtualization and resource allocation, including storing one or more received network requests in a request table (211), and updating (414) at least one of a flow table (209), a waiting list table (213), or a candidate group map (207) based on the one or more received network requests. The updating includes monitoring a transmission progress (416) of each of one or more flows in a network of interconnected computing devices and moving completed flows from the flow table to a success list (418), moving requests in the waiting list table which have reached an attempt threshold from the flow table to a fail list (412), and compiling any residual requests in the waiting list with new requests (422) to generate a new request table (424). A deterministic request allocation (426) and/or an optimizing request allocation (428) is performed based on the new request table (424).

Abstract: Methods and systems for variable rate control include determining a new communications rate in response to measured data traffic patterns. A receive change message is transmitted to a receiver that triggers the receiver to wait for an end of transmission (EoT) message and to set a new communications rate. A transmit change message is transmitted to a transmitter that triggers the transmitter to send the EoT message to the receiver, to set the new communications rate, and to send a start of transmission (SoT) message to the receiver before resuming data communications.
