Abstract(in English) | IP multicast is an effective technology to distribute identical data simultaneously to multiple users. However, for technical and administrative reasons, IP multicast has not been globally deployed on the Internet. Another approach to multicast is application-level multicast. In application-level multicast, multicast related features, such as group membership management, multicast routing and packet replication, are implemented at endhosts instead of routers. Multicast delivery tree is constructed in the application layer, so all nodes in this tree are endhosts. Packet transmission between endhosts uses conventional IP unicast service. However, application-level multicast has a critical drawback that node failure causes multicast tree partitioning. Therefore, robustness is a key issue to application-level multicast which is instrinsically fragile. In this paper, to improve it, we propose new tree building protocol which makes outdegrees of transit nodes be balanced. Degree-balanced multicast trees can reduce the number of nodes decoupled by tree partition. To investigate performance of our protocol, it is compared with the existing application-level multicast protocol. Our simulation results show that our protocol outperforms the exisiting protocol from the view point of robustness and endhost-perceived delay. |
