Abstract: Multi-hop doubleloop networks is a comparatively reliable network topology structure. This paper analyses the capability of network communication with each other between normal nodes under the node failure conditions from one to two.It points out this network in relation to network node number, hop distance, and establishes the mathematics relations under various conditions. It also gives the curve so as to compare.
