Scalable multicast protocol design based on the Bloom filter has received much attention from the research community recently. With the Bloom filter-based design, routing information is carried by the multicast data packet in the format of a Bloom filter. As the network node has no need maintaining a forwarding state for each group it is supporting, the Bloom filter-based multicast protocols are more scalable compared with the traditional IP multicast. However, as these protocols require networking nodes involved to perform special Bloom filter-based processing and the legacy routers can not be all upgraded over night, the incremental deployment solution for the Bloom filter-based multicast protocols is still an open technical issue.
