Abstract
Multiple multicast acknowledgements can be merged into a single multicast acknowledgement, thus reducing traffic and reducing logic complexity. An intermediate node that receives multiple multicast acknowledgements merges the multiple acknowledgements into a single acknowledgement, and then supplies the single merged acknowledgment to the multicast source. Encoding of the single merged acknowledgement conveys to the source which of the multicast targets successfully received (or which failed to receive) the multicast information.
