Network flow monitoring and analysis

摘要

To analyze the performance of a network including edge routers and a hub router coupled together by communication links, an analysis method includes discovering the topology of the network that is initially unknown. An information handling system (IHS) determines baseline performance information with respect to the discovered topology of network, the baseline performance information including network capacity information on a per link basis. The discovered topology of the network is speculatively changed to provide a speculatively changed network with prospects for performance improvement. The IHS determines an estimated impact of the speculative change to the discovered topology of the network by repeating the topology discovery and the determination of baseline performance using the speculative changed topology.

1. A method of network performance determination, comprising:
discovering, by an upgrade analysis application of a first information handling system (IHS), a topology of a particular network that includes a plurality of routers coupled together by a plurality of communication links, the plurality of routers including edge routers and at least one hub router, thus providing a discovered topology, wherein the particular network exhibits traversing traffic flows and terminating traffic flows, wherein the edge routers and at least one hub router provide respective aggregated traffic flows; monitoring, by the upgrade analysis application of the first IHS, the traversing traffic flows and terminating traffic flows of the particular network; receiving, by the upgrade analysis application of the first IHS, aggregated traffic flows from the plurality of edge routers and at least one hub router; determining baseline performance information, by the upgrade analysis application of the first IHS, with respect to the discovered topology of the particular network, the baseline performance information including network capacity information on a per link basis, the determining baseline performance information including using the traversing traffic flows, terminating traffic flows and aggregated traffic flows from the edge routers and at least one hub router as input; speculatively changing, in response to user input, the discovered topology of the particular network to a new user-selected candidate network topology to provide a speculatively changed network; and determining, by the first IHS, an estimated impact of the speculative change to the discovered topology to the new user-selected candidate network topology by repeating the discovering and determining steps.
