    • A technique for discovering the topology of a computer network and which relies on initially resolving the positions of end stations on the network and subsequently resolving the topology of remaining devices. This technique specifically involves querying a port of a managed device for a first address of any packet which it received; querying the same port for a second address of any other packet which the device received; if there is no such second packet, then returning data to a manager and determining if there is another port on the device; if there is such a second address, determining if there is another port on the device; repeating the preceding steps for the other port of the device; and if no such other port exists, repeating all the preceding steps for another managed device on the network.
    • 一种用于发现计算机网络拓扑的技术,其依赖于最初解析网络上终端站的位置,并随后解析剩余设备的拓扑。 该技术具体涉及对被管理设备的端口查询其接收的任何分组的第一地址; 查询该设备接收到的任何其他分组的第二个地址的相同端口; 如果没有这样的第二分组,则将数据返回给管理器并确定设备上是否有另一个端口; 如果有这样的第二个地址,确定设备上是否有另一个端口; 对设备的其他端口重复上述步骤; 并且如果不存在这样的其他端口,则对网络上的另一被管理设备重复所有前述步骤。

    • In a computer network, a method to graphically distinguish on a network map a path between two points on a network. This is particularly useful in diagnosing problems, by tracing a path between two devices. While path tracing may be a relatively simple matter where there are relatively few devices, in a complex network, the paths between two devices will not be immediately obvious and indeed it is desirable to be able to ascertain whether there is more than one such path. There is disclosed a method for selecting a path or paths between two selected points in a network, said network comprising a plurality of points interconnected by links, comprising the steps of deleting from the method all points other than the selected two points having a single link to the remainder of the network to produce a reduced network, and repeating the deletion step until there are no points, other than the two selected points, which are connected to the remaining network by a single link. A computer program for carrying out the method is described.
    • 在计算机网络中,在网络上以图形方式区分网络上两点之间的路径的方法。 这通过跟踪两个设备之间的路径来诊断问题特别有用。 虽然路径跟踪可能是相对较少的设备的相对简单的事情,但是在复杂网络中,两个设备之间的路径将不会立即显现,并且实际上希望能够确定是否存在多于一个这样的路径。 公开了一种用于选择网络中的两个选择点之间的路径或路径的方法,所述网络包括通过链路互连的多个点,所述方法包括以下步骤:从所述方法中删除除所选择的两点之外的所有点, 到网络的剩余部分以产生减少的网络,并且重复删除步骤,直到没有通过单个链路连接到剩余网络的两个所选择的点之外的点。一种用于执行该方法的计算机程序 被描述。
