Document Type and Number:
WIPO Patent Application WO/2013/035286
Kind Code:
A1
Abstract:
In a communication system, a group-to-group broadcast distribution for exchanging or sharing data among communication devices belonging to the same group is performed. Each communication device in the communication system comprises: a Bloom filter transmitting means (501) that transmits, to each of a plurality of neighboring nodes in a tree-like topology, Bloom filter values representative of a list of the identifiers of groups to which node groups existing on the side of the local node as seen from that neighboring node belong; and a group-to-group broadcast communication path establishing means (502) that establishes a forwarding table on the basis of the Bloom filter values received from each neighboring node in the tree-like topology and representative of a list of the identifiers of groups and on the basis of information of the neighboring node having transmitted the Bloom filter values.
