摘要： A method comprises transmitting a plurality of copies of a message from each of a first transmission node and a second transmission node, each copy having a respective identification and forwarding each of the plurality of copies of the message among other nodes in the network based, at least in part, on the respective identification of each copy such that each copy of the message traverses a predetermined communication path among the other nodes. A respective first received copy is compared to a respective second received copy at each of the other nodes. The integrity of the respective first and second copies is validated at each of the other nodes if the copies match and the copies traversed disjoint communication paths.

摘要： A method of communicating data in a network comprises receiving a copy of a message on a first channel via at least one of a first port and a second port, the first port coupled to a first neighbor node and the second port coupled to a first neighbor's neighbor node; and selecting either the copy of the message received via the first port or the copy of the message received via the second port if a copy of the message is received via both the first port and the second port. If a copy of the message is only received via one of the first port or the second port, the received copy of the message is selected. The selected copy of the message is forwarded on the first channel to a second neighbor node via a third port and to a second neighbor's neighbor node via a fourth port; and the integrity of the selected copy of the message is determined based on supplemental integrity data received from another node, wherein the supplemental integrity data is exclusive of a copy of the message communicated on a second channel.

摘要： A communication network comprises a communication medium and a plurality of nodes. Each node is configured to communicate with the other nodes using a protocol that has at least one of an idle period or a preamble period. The at least one node of the plurality of nodes is configured to transmit an out-of-band signal during at least one of the idle period or the preamble period and is configured to modify at least a portion of the out-of-band signal to communicate data to at least one other node. The at least one other node is configured to interpret the modified portion of the out-of-band signal to identify the data communicated in the modified out-of-band signal. The modified out-of-band signal complies with the protocol's encoding rules such that any node not configured to interpret the modified portion of the out-of-band signal processes the modified out-of-band signal according to the protocol.

摘要： A network comprises a plurality of nodes; and a plurality of links communicatively coupling each of the plurality of nodes to at least one respective adjacent node of the plurality of nodes via a first communication channel and to another respective adjacent node of the plurality of nodes via a second communication channel. At least one of the plurality of nodes is a source node configured to source data. The source node is configured to form a virtual self-checking pair with one of the respective adjacent node on the first communication channel or the respective adjacent node on the second communication channel to achieve a consistent broadcast of data on the first and second communication channels. Data exchanged between the source node and the respective adjacent node in the virtual self-checking pair is only sourced by the source node.

摘要： A multi-channel TDMA network having priority based is provided. A network includes a plurality of channels, and a plurality of nodes adapted to transmit and received data. Through each channel, every node is coupled to communicate data with every other node. Within each channel, each node is assigned a unique priority rank. Only the node with the highest priority rank is permitted to transmit data during a time slot. For each channel of the multi-channel network, the plurality of nodes are ranked in a different priority direction.

The method includes monitoring for an expected action of the system that indirectly identifies the operating condition of the first component to a second component of the system, when the monitored expected action indicates a faulty operating condition, isolating the first component's errant behavior, and when the monitored expected action indicates a proper operating condition, proceeding with normal operation of the system.

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.
