摘要： The goal of the present invention is to improve the useful data efficiency and reliability in the use of commercially available ETHERNET controllers, in a distributed real time computer system, by a number of node computers communicating via one or more communication channels by means of TT ETHERNET messages. To achieve this goal, a distinction is made between the node computer send time (KNSZPKT) and the network send time (NWSZPKT) of a message. The KNSZPKT must wait for the NWSZPKT, so that under all circumstances, the start of the message has arrived in the TT star coupler at the NWSZPKT, interpreted by the clock in the TT star coupler. The TT star coupler is modified, so that a message arriving from a node computer is delayed in an intelligent port of the TT star coupler until the NWSZPKT can send it precisely at the NWSZPKT into the TT network.

摘要： One embodiment comprises a network that includes a plurality of bi-directional links and a plurality of nodes. Each node is communicatively coupled to two neighbor nodes and to two skip nodes using the plurality of bi-directional links. Three neighboring nodes of the plurality of nodes form a triple modular redundant (TMR) set having a first end node, a second end node, and a center node, the first end node configured to transmit output data in a first direction and the second end node configured to transmit output data in a second direction. At least one of the plurality of nodes that is not in the redundant set determines the integrity of data received from the redundant set based on at least: (i) a comparison of data received on a first logical communication channel from a respective first neighbor node with data received on the first logical communication channel from a respective first skip node; (ii) a comparison of data received on a second logical communication channel from a respective second neighbor node with data received on the second logical communication channel from a respective second skip node; and (iii) a comparison of data received on the first logical communication channel from one of the respective first neighbor node and the respective first skip node with data received on the second logical communication channel from one of the respective second neighbor node and the respective second skip node.

摘要： In one embodiment, a node comprises an interface to communicatively couple the node to a channel. The channel communicatively couples the node to a first neighbor node and first neighbor's neighbor node in a first direction. When the first neighbor node is scheduled to transmit and the node receives data from the first neighbor node via the channel, the node forwards the data to the first neighbor's neighbor, receives other data from the first neighbor's neighbor, compares the data to the other data, and relays the data along the channel with information indicative of the comparison.

摘要： A half-duplex communication network comprises a plurality of communication links, each link being configured a priori to communicate in one direction; and a plurality of nodes, each node coupled to a first and second direct neighbor nodes and a first and second skip neighbor nodes via the plurality of communication links. Each node comprises propagation logic adapted to arbitrate conflicts between concurrent messages based on at least one of higher level policies and a comparison between a priority of each message, wherein each node is adapted to communicate a message without waiting to determine if another node is transmitting another message with a higher priority.
