Abstract
Systems and methods reliably transmit a message from a sender to a receiver via a network. A reliability module is configured to determine a probability of delivering a packet from the sender to the recipient via the network. Mode selection logic determines transmission mode from a number of options based upon the probability of delivering the packet from the sender to the recipient. A formatting module is configured to provide a first push that includes the message and, in at least one of the operating modes, a number of redundancy packets formulated as a function of the contents of the message. The receiver acknowledges the packets received so that any dropped packets can be re-transmitted. The redundancy packets can be created using Reed-Solomon or other forward error-correcting codes to further increase the reliability of the message transmission when network conditions warrant.
