Abstract:
1. A method in a frame relay transmission to make efficient use of bandwidth comprising: maintaining separate queues to store realtime data and non-realtime data to be transmitted; providing a fragment queue to hold fragments of data to be transmitted; checking in order to determine whether the realtime data queue and then the non-realtime data queue is empty; transmitting realtime data in successive packets when the realtime data queue is not empty; fragmenting non-realtime data dynamically according to available transmission bandwidth including determining fragment sizes according to available burst intervals; and transferring fragmented non-realtime data to the fragment queue for transmission after transmission of realtime data: setting values for a maximum number of expected voice calls, for access rates of link devices within the system, for voice sampling and compression rates, and for acceptable voice traffic delays; ascertaining a burst interval based on the acceptable voice traffic delays value; calculating a value of a committed burst size based on the burst interval divided by the access rates of link devices; and computing a fragment size according to the committed burst size less overhead and size of voice fragments.
