Issue No. 11 - November (2007 vol. 18)
In this paper, we propose a new multicast delivery mechanism for bandwidth-demanding applications in IP networks. Our mechanism, referred to as Multiple- estination Overlay Multicast (MOM), combines the advantages of IP multicast and overlay multicast. We formulate the Multiple-destination Overlay Multicast routing problem as an optimization problem. We then design an algorithm based on Lagrangean relaxation on our formulation and propose a distributed protocol based on the algorithm. For network operators, MOM consumes less network bandwidth than both IP multicast and overlay multicast. For end users, MOM uses less interface bandwidth than overlay multicast.
