Abstract: An apparatus including a port to transmit first frames and receive second frames over a communication channel, the port including a collision detect circuit and a duplex mismatch circuit. The collision detect circuit detects collisions on the communication channel between the first frames and the second frames. The duplex mismatch circuit declares a duplex mismatch when the communication channel was established without attempting auto-negotiation, the port is in a half-duplex mode, and the collision detect circuit detects a very late collision involving one of the first frames. The very late collision occurs after a predetermined amount of data has been transmitted in the one of the first frames. The duplex mismatch indicates that a full-duplex mode is used with respect to the second frames.

Abstract: A new random linear network coding scheme for reliable communications for time division duplexing channels is proposed. The setup assumes a packet erasure channel and that nodes cannot transmit and receive information simultaneously. The sender transmits coded data packets back-to-back before stopping to wait for the receiver to acknowledge (ACK) the number of degrees of freedom, if any, that are required to decode correctly the information. Provided herein is an analysis of this problem to show that there is an optimal number of coded data packets, in terms of mean completion time, to be sent before stopping to listen. This number depends on the latency, probabilities of packet erasure and ACK erasure, and the number of degrees of freedom that the receiver requires to decode the data. This scheme is optimal in terms of the mean time to complete the transmission of a fixed number of data packets.

Abstract: Devices and methods are disclosed which supplement a duplex frequency by providing one or more simplex frequencies and distributing data among them. Variations of the disclosed system include a server in communication with a communications device using a duplex channel. The server includes a scheduler that determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and one or more simplex channels. Before sending this data, the server sends a schedule to the communications device through the duplex channel, so the communications device knows which bits of data are coming through which channels and at which times. A descheduler within the communications device receives the schedule and alerts the communications device to start receiving data on other simplex channels. The descheduler then puts the bits of data in order as they stream in across the duplex and simplex channels.
