为了高效、可靠地完成各个网络节点的配置文件同步任务,设计了一种基于CAN覆盖网络的配置文件同步模型。为了适应广播应用,优化了CAN覆盖网络的相关实现机制,包括节点加入退出机制以及失效恢复机制。优化后的CAN网络空间划分更均匀,失效恢复速度更快,网络的健壮性更强。另外,和传统的树状分发模型相比,该配置同步模型具有较好的扩展性和低延迟性,配置同步所产生的下载流量不会随着节点数量的增加而线性增加。
In order to accomplish the synchronization tasks of each network node,a synchronization model based on CAN overlay network is designed. In order to adapt to broadcast applications,the implementation mechanism of CAN overlay network is optimized,including the node joining mechanism and the failure recovery mechanism. In the optimized CAN network,space division is more uniform,the failure recovery speed is faster,and the network's robustness is stronger. Compared with the traditional tree distribution model,the configuration synchronization model has good scalability and low delay. The download traffic generated by the synchronization will not increase linearly with the number of nodes.
