    Abstract: A slotted message access protocol can be implemented for transmitting messages in a communication network. A beacon period may be divided into multiple communication slots. A master network device may register a first client network device and provide registration information to the first client network device. The registration information may include one or more encryption keys to allow the first client network device to securely transmit messages in the communication network. The client network device may use an encryption key associated with a second client network device to decrypt messages received from the second client network device. Furthermore, the first client network device may use a contention-based communication slot to request allocation of contention-free communication slots for subsequent transmissions. The master network device may temporarily allocate contention-free communication slots to the client network device for a specified duration.

    Abstract: Protocol data units (PDUs) associated with a packet stream are transmitted with sequence numbers to support reordering and selective acknowledgement. A selective acknowledgement (SACK) message may be used to indicate at least one sequence number of a lost or corrupted PDU which was not properly received by the receiving device. Responsive to the SACK message, the lost or corrupted PDU is retransmitted via a different path of the network, different from the path used to transmit the original PDU. Lost or corrupted PDUs may not be retransmitted if the estimated retransmission delay is greater than a delay tolerance associated with the quality of service requirements of the application. Instead, a control message (i.e. cut losses message) may be transmitted to indicate that PDUs earlier than a particular sequence number will not be transmitted.
