摘要： Methods and systems for sensing conditions of a fiber include splitting a light signal into two branches. A first branch is converted to have a mode different from that of the second branch. Both branches are mode multiplexed into a single fiber. An output of the fiber is mode demultiplexed into the two branches. The first branch is mode converted to its original mode. Brillouin scattering patterns of the two branches are compared to determine a temperature and strain profile of the fiber.

摘要： Systems and methods for data transport, including receiving one or more signals into a reconfigurable and flexible rate shared rate multi-transponder network architecture, wherein the network architecture includes one or more transponders with multiple line side interfaces and one or more client side interfaces. The transponders are configured to map one or more signals to multiple parallel Virtual Ethernet Links, remove idle characters from the one or more signals, buffer one or more blocks of characters using an intermediate block buffer, activate and deactivate one or more portions of input/output electrical lanes of an Ethernet module, multiplex and demultiplex the one or more signals to and from the input/output electrical lanes to enable sharing of a single optical transceiver by multiple independent signals, and insert blocks of idle characters to enable transmission over a lower rate transmission pipe.

摘要： A generic centralized, software-defined networking configuration for connecting network is defined as a generic multi-layer topology network entities interconnected either vertically or horizontally regardless of the employed network topology/graph). This centralized configuration enables establishment of a connection between any two networking entities by 1) bypassing intermediate protocol layers and 2) eliminating any handshaking between peer elements of the same layer. The centralized software-defined controller notifies in parallel all involved network entities along a connection path to take all necessary actions (i.e. reconfiguration) to establish the new connection. The centralized controller has authority to control only entities that are software-defined SD.

摘要： 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.
