Abstract
Media that is normally packetized into many separate individual packets and then queued for individual transmission during a transmit window is combined together into one, or a few, packets. The larger packets more efficiently carry media over a time slotted communication media since only one, or a few, packet headers are used for carrying a larger amount of media. Since packets cannot be transmitted until the start of a new transmit window, the larger packets do not substantially add to the overall packet delay that normally occurs when larger packets are formatted and transmitted in non-time slotted networks.In another aspect of the system, probe packets are used to identify the start of the transmit window. The transmit window start time is inferred from the round trip times for the probe packets and media packetization is then synchronized with the identified transmit windows.
