    摘要: Potential paths between a source and destination of a network are identified based on trace-route information, then filtered to eliminate paths or links that are not supported by ancillary information associated with the network so as to identify feasible/actual paths between the source and destination. The ancillary information includes, for example, routing tables and ARP tables. If a feasible path cannot be identified based on the ancillary information, supplemental information regarding nodes further along the potential path is assessed to provide a basis for inferring the nodes that may provide a feasible path. The determined feasible paths are displayed for review, and provided to serve as filters for subsequent path-analysis tools.

    摘要: A network analysis system invokes an application specific, or source-destination specific, path discovery process. The application specific path discovery process determines the path(s) used by the application, collects performance data from the nodes along the path, and communicates this performance data to the network analysis system for subsequent performance analysis. The system may also maintain a database of prior network configurations to facilitate the identification of nodes that are off the path that may affect the current performance of the application. The system may also be specifically controlled so as to identify the path between any pair of specified nodes, and to optionally collect performance data associated with the path.

    摘要: A network is partitioned into a set of independent partitions, and the topology of each partition is determined, then merged to form a topology of the entire network. Preferably, the partitioning is hierarchical, wherein the network is partitioned to form individual VLAN partitions, and each of the VLAN partitions is further partitioned based on the nodes that are simply connected to each port of one or more selected root switches within the VLAN partition. Simple connections to each port are efficiently determined based on an aggregate address forwarding table associated with each node. Ancillary information, such as spanning tree or CDP data, may be used to facilitate efficient partitioning and/or to validate inferences that are made with incomplete information.
