摘要： A system comprises a plurality of nodes, at least one of the plurality of nodes configured to insert, on a per-virtual link basis, a delay value into a dynamic delay field of a frame corresponding to the respective virtual link, wherein the dynamic delay value represents latency of frames of the respective virtual link. The system also comprises a switch having a plurality of ports, each port coupled to one of the plurality of nodes. The switch is configured to route frames received from the plurality of nodes to one or more of the plurality of nodes. At least one of the plurality of nodes is configured to store frames received from the switch in a buffer and to update the value in the dynamic delay field to reflect the end-to-end system delay.

摘要： A system and method for maintaining spatio-temporal data for a given area (e.g., an airspace) containing a given node (e.g., an aircraft) and one or more other nodes (e.g., aircraft). The given aircraft may break the given airspace into a first plurality of smaller airspaces, and may also break the given airspace into a second plurality of smaller airspaces. The given aircraft may then detect local spatio-temporal data for each smaller airspace located within its detectable range. The aircraft may also receive remote spatio-temporal data for the smaller airspaces from the one or more other aircraft. Thereafter, the aircraft may update stored spatio-temporal data based on the aircraft's navigation data, the local spatio-temporal data, the remote spatio-temporal data, and/or a reliability of the data. Further, the aircraft may transmit the stored spatio-temporal data for receipt by the one or more other aircraft.

摘要： A method for optimizing a wireless network comprises obtaining local measurement and feedback data from a single node in the network; estimating a state of the node by using the local measurement and feedback data in an analysis framework model of the wireless network; applying the estimated state of the node to a local control law to determine one or more local protocol parameter updates for the node; and transmitting the one or more local protocol parameter updates to the node in the network. The method can further comprise obtaining global measurement and feedback data from one or more additional nodes in the network; estimating a state of the one or more additional nodes by using the global measurement and feedback data in the analysis framework model; applying the estimated state of the one or more additional nodes to the local control law; applying the estimated state of the one or more additional nodes to a global control law to determine one or more network-wide protocol parameter updates; and transmitting the network-wide protocol parameter updates to the network.

摘要： A clock module is coupled in parallel to a number of data processing modules that are coupled in series. The data processing modules can be individually clock-gated. Each of the data processing modules can determine whether or not it can be placed into an idle state. To reduce power consumption, any subset of the data processing modules that are eligible to be placed in an idle state can be clock-gated. The remaining data processing modules can continue to receive clock signals from the clock module and thus can continue to process data.

摘要： Methods and apparatus are provided for evaluating the performance of a Time Triggered Ethernet (TTE) system employing Time Triggered (TT) communication. A real TTE system under test (SUT) having real input elements communicating using TT messages with output elements via one or more first TTE switches during a first time interval schedule established for the SUT. A simulation system is also provided having input simulators that communicate using TT messages via one or more second TTE switches with the same output elements during a second time interval schedule established for the simulation system. The first and second time interval schedules are off-set slightly so that messages from the input simulators, when present, arrive at the output elements prior to messages from the analogous real inputs, thereby having priority over messages from the real inputs and causing the system to operate based on the simulated inputs when present.
