Abstract
A multicast query propagation scheme for a Peer-to-Peer (P2P) network is provided. A number of first level (L1) peer nodes are associated with a second level (L2) peer node to form an L1 peer group. The L2 peer node operates as a super peer node for the L1 peer group and allocates two Source-Specific Multicast (SSM) channels operating as a control and query channel for the L1 peer group. Similarly, a number of other L1 peer groups are formed. An L2 peer group is formed by a third level (L3) peer node and the L2 peer nodes. The L3 peer node operates as a super peer node for the L3 peer group and allocates two SSM channels operating as a control and query channel for the L2 peer group. Using the control and query channels of the L1 and L2 peer groups, queries are propagated throughout the P2P network.
