摘要： A packet-switched multiple-access network system with a distributed fair priority queuing media access control protocol that provides multiple levels of priority of access and fair collision resolution with improved performance is disclosed. In one embodiment, the system provides high-speed transport of multimedia information on a shared channel. Further, in one embodiment, MAC level side-band signaling that is useful to other levels of the network protocol (e.g., the physical layer) is also provided.

摘要： A transceiver method and signal therefor embodied in a carrier wave for sending information from transmit stations to receive stations over a transmission medium of a frame-based communications network. The information is sent in transmit frames having a frame format comprising a fixed rate header, followed by a variable rate payload, followed by a fixed rate trailer. The fixed rate header includes a preamble. The preamble has a repetition of four symbol sequences for facilitating power estimation, gain control, baud frequency offset estimation, equalizer training, carrier sensing and collision detection. The preamble also includes a frame control field. The frame control field has scrambler control information for frame scrambling initialization, a priority field to determine the absolute priority a transmit frame will have when determining access to the transmission medium, a payload encoding field which determines constellation encoding of payload bits in the variable rate payload, and a header check sequence for providing a cyclic redundancy check. The variable rate payload is transmitted pursuant to dynamic adjustable frame encoding parameters for improving transmission performance for a transmit frame being transmitted from a transmitting station to a receiving station. The header also includes a destination address field, a source address field and an ethertype field.

摘要： A method of transmitting and receiving data packets over a channel susceptible to random burst and/or white gaussian noise channel errors. Each data packet is encoded to form error correctable encoded data packets. Each error correctable encoded data packet is interleaved to form interleaved error correctable encoded data packets. Each interleaved error correctable encoded data packet is modulated to form modulated interleaved error correctable encoded data packets. Each modulated interleaved error correctable encoded data packet transmitted is over the channel. The encoding includes performing Reed Solomon encoding on each data packet to form Reed Solomon error correctable encoded data packet. Each data packet is cyclic redundancy check encoded prior to performing Reed Solomon encoding.

摘要： A method and apparatus for verifying connectivity between network nodes in a communications network. For each node periodic time intervals are provided. Elapsed periodic time intervals are counted since transmission of a link integrity indication frame, the link integrity indication frame being a frame which, when transmitted by a network node, can be received by all other nodes on the communications network and which contains a source identifier, such as a source address, that uniquely identifies a transmitting node. Frames are received from a sending node and a node state status and a current received frame source address are maintained during each periodic time interval. Upon the expiration of a predetermined elapsed time interval the node state status and a count of the elapsed periodic time intervals since transmission of a link integrity indication frame are determined. A link integrity indication frame is transmitted based upon determining the count of predetermined elapsed time intervals as being greater than a predefined count limit and the node state status as not being indicative of network traffic.

摘要： An in-home network which includes a telephone line and a plurality of consumer electronic devices coupled to the telephone line. Each of the consumer electronic devices is assigned a unique address, such that each of the consumer electronics devices is individually addressable via the telephone line. The consumer electronic devices communicate using a packet-based protocol, wherein each of the consumer electronic devices transmits analog signal bursts on telephone line. Each of the consumer electronic devices can include a wireless signal receiver, such that a first consumer electronic device can receive control information from a remote control, and then control the operation of a second consumer electronic device by transmitting the control information to the second consumer electronic device via the telephone line.
