摘要： In embodiments, a transmitting device sends a time reference field to a receiving device when indicating that no more frames will be sent to the receiving device. The time reference informs the receiving device of the length of time that the transmitting device has committed not to transmit to the receiving device. When operating in conformance with the ECMA-368 standard, the time reference allows the transmitting device to control the length of the commitment period after the MORE FRAMES bit is set to zero. In this way, the commitment not to transmit may be made for a shorter time than the time until the beginning of the following Distributed Reservation Protocol (DRP) reservation block or the time to the beginning of the following superframe. The time reference may be added in the Medium Access Control header or included in a vendor-specific message, for example.

摘要： A system includes a direct memory access (DMA) engine to move data on a real time basis and a communication front-end to transmit and receive the data. In another embodiment, the system may also include a medium access control (MAC) to control transmission and reception of the data and that may be partitioned or divided according to response times to carry out selected functions.

摘要： A computer system for transmitting two or more types of signals. Each type of signal is assigned a priority level. Signals of a particular type are transmitted as they become ready for transmission, unless signals of a different type having a greater priority become ready for transmission. In that case, the transmission of the low-priority signals is interrupted to allow transmission of the high-priority signals. The transmission of the low-priority signals is resumed after the transmission of the high-priority signals is complete. In a preferred embodiment directed to conferencing systems, audio signals are assigned higher priorities than video, data, and control signals in order to provide a high-quality to the audio portion of a conferencing session.
