System and method for analysis of communications networks
First Claim
1. :
- A method of modeling a network, comprising the steps of;
acquiring one or more metrics associated with one or more network hops;
calculating one or more performance ratings from the one or more metrics for the one or more network hops; and
computing an overall baseline capability of the one or more network hops based on the calculating step for use in at least any one of characterizing impacts of one or more applications, identifying diminished performance by a network component and projecting an effect caused by altering the network component.

Abstract
A system and method is provided for using network asset management data including attributes such as device type, location, and link speed for modeling network performance and identifying performance issues. The invention provides measured and observed performance data for one or more segments of a network (e.g., one or more hops or end to end) so that identification of diminished performance in the network might be accomplished. Additionally, the invention may provide projections of performance impacts based upon proposed changes to one or more components in the network. Performance metrics, ping times, MIB data, link speeds, propagation delays, device latency, serialization rates, conversational speeds, conversational utilization and other data are used to model a network for determining or isolating problematic issues and to forecast performance impacts of potential changes to the network.
