In the existing structured peer-to-peer (P2P) application layer multicast schemes, the end-to-end delay from the source to group members is high and the multicast delivery tree is unstable. In order to overcome these demerits, this paper presents a new P2P application layer multicast protocol named DOMulti. In this protocol, the Tapestry routing and the data location service are utilized to construct a multicast delivery tree with bounded depth and constrained out-degree of node. As there are no non-group members in the delivery tree, the transmission delay between the source and group members can be optimized and the stability of the tree can be improved. Simulated results indicate that, as compared with the existing protocol, DOMulti is of distinct advantages in terms of end-to-end delay and is more suitable for the delay-sensitive multicast applications in P2P environment.
