The gain and cost of multicast routing trees
Milena Janic, Piet Van Mieghem · 2005
The last several years we witness the proliferation of multimedia applications on Internet. One of the unavoidable techniques to support this type of communication is multicasting. However, even a decade after its initial proposal, multicast is not widely deployed. One reason lies in the lack of a business model. If the gain and the cost of multicast could be predicted, network operators might be encouraged to deploy multicast on a larger scale. We propose several analytical expressions that could be used to estimate the gain and cost of network-layer multicast. We show that the theoretical model we propose matches simulation and Internet measurement results remarkably well.
