The availability of a connectionless network (10) is determined by first identifying all possible data destinations. Stated another way, all possible network endpoints are determined. Thereafter, the routing tables (36, 38 and 40) within the routers (12, 14, 16) of the network are examined to determine whether a route exists to each endpoint. The availability of the network is then established by comparing the available routes to endpoints to the number of endpoints. If a route exists to every endpoint, then the network 10 is fully available. The lack of a route to an endpoint diminishes network availability.
