    • A network router is tested for operation according to a given network protocol, by coupling the router under test (RUT) to a test host device and arranging the device to simulate operative test network topologies which include router nodes, network nodes, and edges between the nodes. The device exchanges information packets with the RUT for each of a number of successive test network topologies. Each successive topology is determined randomly by inserting or deleting an edge or a node to or from a prior test network topology in a probabilistic manner. Operation of the RUT under the given protocol is evaluated based on the exchanged information packets. A judgment, e.g., a fault or a no-fault condition, is rendered by the host device.
    • 网络路由器根据给定的网络协议进行测试,通过将被测试路由器(RUT)耦合到测试主机设备,并安排该设备来模拟包括路由器节点,网络节点以及路由器节点之间的边缘的操作测试网络拓扑 节点。 设备与多个连续测试网络拓扑中的每一个交换具有RUT的信息分组。 通过以概率的方式向先前的测试网络拓扑插入或删除边缘或节点来随机确定每个连续拓扑。 根据交换的信息包评估给定协议下的RUT的操作。 判断,例如故障或无故障状态由主机设备呈现。
