摘要： In one embodiment, a method resolves cliques formed in a network comprising a plurality of nodes that are communicatively coupled to one another over at least a first channel. The method comprises, at each node, wherein that node is a member of a current clique: listening asynchronously for data on the first channel from a first neighbor's neighbor node of that node. The method further comprises, at that node, when a first valid frame is received on the first channel from the first neighbor's neighbor node of that node, listening asynchronously for a second valid frame on the first channel from a first neighbor node of that node. The method further comprises, at that node, when the second valid frame is received on the first channel, checking if the first valid frame and the second valid frame are both from the same other clique, and, if the first valid frame and the second valid frame are both from the same the same other clique, determining if that node should defect from the current clique towards the other clique.

摘要： A communication protocol and hardware is provided which allows a meshed network to reliably perform in a real-time environment. The protocol establishes that within specified regions of a mesh, a single node will transmit on that region at any given time. The transmitted message is propagated to all other nodes in the region by flooding the network. Immediately upon receiving each bit of data, a receiving node will immediately retransmit that bit, thereby increasing the speed of the flooding. Arbitration and lockout logic is provided which assures that nodes receiving data from multiple sources will be able to correctly handle and retransmit that data.

摘要： The present invention provides a method for transmitting large data messages over networks. In one embodimen□□t, this is accomplished by partitioning the large data message into smaller packets. The packets are transmitted over the network in reverse sequential order, from the last created packet to the first created packet. Either the transmitter or the receiver attaches the packet control information to the packets. Immediately after each packet is transmitted and received by at least one receiver, it is written into a memory pre-allocated memory location. Subsequently transmitted and received packets e written into locations adjacent previously written packets, however, they are shifted in position such that a portion of the packet overwrites the packet control information that was attached to the previously written packet. This is repeated until all of the packets have been transmitted and written and the large data message reintegrated and coherent.
摘要翻译：本发明提供一种通过网络发送大数据消息的方法。在一个实施方案中，这是通过将大数据消息分割成更小的分组来实现的。分组以反向顺序从网络传输，从最后创建的分组到第一个创建的分组。发送器或接收器将分组控制信息附加到分组。在每个分组由至少一个接收机发送和接收之后，立即被写入存储器预先分配的存储器位置。随后发送和接收的数据包e被写入与先前写入的数据包相邻的位置，但是它们被移位的位置使得该数据包的一部分覆盖附加到先前写入的数据包的数据包控制信息。这一直是重复的，直到所有的数据包都被传输和写入，并且大数据消息重新集成和连贯。

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 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.
