A contention-free burst method for a media access controller to transmit data over a network. The first step is to create descriptors identifying multiple frames to be transmitted by a contention-free burst. Each descriptor comprises a semaphore field indicating whether the frame associated therewith is the last within the contention-free burst, and comprises an exchange time field recording duration of the frame associated therewith. The frames are transferred to a media access controller initiating the contention-free burst. The media access controller tracks an actual amount of elapsed time from when the burst is initiated. The contention-free burst is terminated either when a granted period less the actual amount of elapsed time results in insufficient time for any remaining transmission, or upon detection of a descriptor with a semaphore field indicating the last frame in which case termination is executed following transmission of the frame determined to be last.
