PREDICTING THE PERFORMANCE OF A MULTI-STAGE COMMUNICATIONS NETWORK UNDER LOAD FROM MULTIPLE COMMUNICATING SERVERS

摘要

A capability is provided for predicting the performance of a communications network, such as a multi-stage communications network. The predicted performance includes, in one aspect, predicting the amount of bandwidth that a server of the communications network could deliver with a full load on the network. In one aspect, the predictive capability includes determining an aggregate load for each server of the network being analyzed; performing normalization on the loads of the links used by the servers to obtain updated link and/or server bandwidths; and determining for each server, a minimum bandwidth over the links in the server's route.

1. A computer program product for predicting the performance of a server of a communications network, the computer program product comprising:
a storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method, the method comprising:
determining an aggregate communications load for the server of the communications network, wherein the aggregate communications load is based on a plurality of link loads for a plurality of links to be used by the server;based on the aggregate communications load, normalizing the plurality of link loads to obtain a plurality of normalized link loads; andusing the plurality of normalized link loads, determining a server bandwidth for the server, the server bandwidth providing an indication of the performance of the server.
