A novel fault detection mechanism of topology-aware ALM

The fault detection mechanism of existing topology-aware ALM protocol is very simple which greatly weakens its performance. So it needs a more efficient mechanism to ensure the robustness and QoS of ALM. We propose a novel fault detection mechanism named REW (Reverse-inhibition Early Warning) which can send warning message before the buffer data are consumed away to avoid the termination of service. It can reduce the number of repetitive and wrong warning through reverse-inhibition strategy at the same time. The simulation results show that REW fault detection mechanism can reduce disconnection delay caused by multicast members' fault with low maintain and control overhead.
