Our mechanism, referred to as Multiple-destination 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. © 2007 IEEE.application/pdfapplication/pdfApplication-layer multicast; Overlay multicastBandwidth; Internet protocols; Lagrange multipliers; Multicasting; Optimization; Interface bandwidth; Multicast delivery mechanism; Multiple-destination overlay multicast; Network routingjournal article10.1109/TPDS.2007.11042-s2.0-35348891487WOS:000249702800002
