In the process of network switching, it often appears unstable network hop signal, the single frequency pulse formnetwork fluctuation, network stability and security is affected. The single frequency pulse envelope instantaneous effectivestatistics is needed, it can be used to suppress the fluctuation pulse cancellation method, and improve the performance ofnetwork. A reverberation statistical model of unstable network is proposed based on jump single frequency pulse envelopeinstantaneous statistical method. Construction of network hop reverberation statistical model of single frequency pulse istaken, pulse signal reverberation modeling is obtained, and then the impulse response of reverberation signal generated inthe network and unstable jump. The unit reverberation statistics method is improved on the traditional values of the instan-taneous envelope statistics algorithm. The results show that the instantaneous pulse envelope values can be effectively com-puted for unstable network, statistical results are accurate, it can effective responses envelope change, and it can improvethe performance of network.
