Graph Construction Method and Restoration Method for Application Level Multicast Using Network Coding Otake, Kenji 90396797 白石, 陽 60381282 高橋, 修 metadata only access This paper proposes a graph construction method and restoration method for application level multicast (ALM) using network coding (NC). We tested and evaluated the proposed methods. Multicast communications have received a lot of attention in recent years because network load is increasing. There are two types of multicast communications: IP multicast and ALM. More flexible ALM has attention focused on it and is an active area of research. Network efficiency of ALM is lower than that of IP multicast. Therefore, we focus on NC to improve communication efficiency of ALM. When NC is applied to ALM, a special path design is needed unlike usual ALM. In addition, nodes often leave ALM because it consists of end hosts. We developed a graph construction method and restoration method for when NC is applied to ALM. We conducted an experiment to evaluate these methods. We evaluated delay and throughput to prove that our proposal is better than existing ALM. In addition, we measured overhead when paths were restored when nodes left and verified the method's practicality.
