本文针对不完全超立方体多播网络中节点状态变化导致的连通度低结构维护难的问题，在原有HyperCast和CubeFullDist结构的基础上，采用为节点保存次邻节点信息以及在节点物理连接丢失时建立逻辑连接的方法，提出了一种改进的超立方体多播拓扑控制协议Hypercastplus。理论分析与仿真实验表明,Hypercastplus具有更好的容错性。

Reliable and scalable multicast is an active research field of multicast based on hypercube. Hypercastplus based on HyperCast and CubeFullDist is presented to solve the problem of multicast reliability. Because the nodes in multicast may leave or join at any moment, it is difficult to maintain. The mechanism is implemented by saving the information of the node’s neighborhoods and adding logic links when the physical links are missing. According to the theoretial analysis and simulations, the Hypercastplus protocol shows more efficient reliability.
