Shared-Tree Selection Method for Aggregated Multicasts
Yusuke Sekine, Toyofumi Takenaka (Nihon Univ.) NS2011-227
Abstract (in Japanese) (See Japanese page) 
(in English) Aggregated multicast methods have been proposed in order to reduce the size of routing tables in routers for multicast communications, where plural multicast sessions share some single multicast tree called Shared-Tree.STA (Scalable-Tree-Aggregation) method has been proposed as a Shared-Tree selection method, where a minimum Shared-Tree has been selected among Shared-Trees which contain all destination nodes of a multicast session.In the STA method, the selected Shared-Tree sometimes contains unnecessary nodes for the multicast session and causes the unnecessary traffic load.
In this paper, we use smaller Shared-Trees compared with the multicast session by grafting some destination nodes to the Shared-Trees.By this grafting method, we can expand search range of Shared-Trees and select a Shared-Tree, destination nodes of which correspond to them of the multicast session as much as possible.We implement this selection method using the overlapping degree of destination nodes and reduce unnecessary traffic load.We also evaluate our selection method by simulation experiments and show the effectiveness of our proposed method.
