Abstract

This article describes a technique which provides for a positive acknowledgement for broadcast frames on an insertion ring which guarantees receipt of the broadcast frames. A bit field is used by the nodes on the ring to acknowledge the broadcast. With the advent of the insertion ring concept which effectively isolates each message to only one receiver at a time on the ring, positive acknowledgements of the broadcast frames can be provided as a part of the broadcast frame itself. This is accomplished by providing a bit field in the broadcast frame which is equal in size to the maximum number of addresses on the insertion ring. If, for example, an insertion ring node could have an address of any number between 0 and 127, then a bit field of 128 bits would be defined in the broadcast frame.
