On the use of on-demand layer addition (ODL) with mutli-layer multicast transmission techniques
Vincent Roca · 2000
This work deals with the multicast transmission of data using multiple multicast groups. One reason to use multiple groups is to address the potential heterogeneity of receivers. But there is a risk that some of the groups are not used and sending data to a group with no receiver has many costs that are often underestimated. As IP multicast becomes widely deployed and used, these issues may well compromise its scalability.
