System and method for problem resolution in communications networks
First Claim
1. A method of managing a network, comprising the steps of:
- modeling performance of a network having one or more network components to locate an instance of a mathematically impaired network component based on any combination of network speed, latency, tuning and utilization;
providing predictive modeling of potential changes to the network, including effects on performance of additional traffic, link speed increases, and chances in distance between clients and servers, thereby increasing a speed of problem resolution of one or more network components that slow overall performance across network connections due to queue build up, propagation delay, or slow serialization or processing of network traffic; and
modifying one or more parameters associated with the one or more network components based on the modeling to improve network performance.

Abstract
A system and method for using network asset management data including device type, location, and link speed for modeling network performance and identifying performance issues. Functionally complete mathematical characterization of a system may be employed to create a system for problem recognition and resolution, wherein disruptive changes to physical and logical system components are only performed when necessary. Mathematical analysis of pings, MIB, and other asset data may be performed separately and the results compared to “self-check”, form, and verify the complete mathematical characterization of a network system. The invention may provide projections of performance impacts based upon proposed changes to 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.
