  • Rate attenuation systems, methods and computer program products for reducing low priority video frame packets transmitted over a network
    Patent number: 6192032
    Abstract: A video frame transmitter for transmitting video frame packets into a communications network includes a traffic smoother for adjusting video frame packet transmission rates; a token bucket for controlling video frame packet entry into the network; and a transmission rate attenuator for adjusting video frame packet transmission rates. The traffic smoother adjusts transmission rates from a video frame source to meet a transmission delay bound of the frame source. Video frame packet transmission rates are attenuated to conform with the state of the token bucket in order to maintain a high percentage of high priority video frame packets entering the network. The rate attenuator allows the traffic smoother and token bucket to work together to reduce the number of low priority packets entering the network.
