Placement of repair proxies to improve inter-receiver delivery delay fairness in hierarchical reliable multicast networks
Sang‐Seon Byun, Chuck Yoo · 2005
In hierarchical reliable multicast schemes, the number of repair proxies and their locations influence inter-receiver delivery delay fairness. Improving inter-receiver delivery fairness is beneficial to synchronized communication in multi-conference or interactive systems. In this paper, we propose a scheme to find the optimal locations of repair proxies that can improve inter-receiver delivery delay fairness maximally in heterogeneous network environments when the number of available proxies is limited. Our evaluation results show that if repair proxies are placed by the proposed scheme, delivery delay fairness can be improved by 0.05 maximally.
