Abstract: hhis paper presented a safe delivery method with low-load and self-configuration. The safe delivery method delivers subscription information effectively in the largcscale networking applications. It allows the terminal to complete more work which is based on the principle of the lowest network overload. Meanwhile, it provided a network self-configuration way which has a good fault tolerance to deal with the situation when nodes come to a failure or when the network needs to add new nodes, thus it better adapts to the largcscale networking applications. Experiments proved thecorrectness of the delivery method.
