Forward looking infrastructure re-provisioning
First Claim
1. A method for re-provisioning a network infrastructure, comprising:
- monitoring performance metrics of a network component;
performing time series analysis on the metrics to obtain predicted next samples for each metric;
weighting and combining the predicted next samples to determine an estimated service level metric during a predictive period; and
determining a probability of whether the estimate of the service level metric will exceed a threshold value defined by a service level agreement.

Abstract
The present invention provides systems and methods for predicting expected service levels based on measurements relating to network traffic data. Measured network performance characteristics can be converted to metrics for quantifying network performance. The response time metric may be described as a service level metric whereas bandwidth, latency, utilization and processing delays may be classified as component metrics of the service level metric. Service level metrics have certain entity relationships with their component metrics that may be exploited to provide a predictive capability for service levels and performance. The present invention involves system and methods for processing metrics representing current conditions in a network, in order to predict future values of those metrics. Based on predicted service level information, actions may be taken to avoid violation of a service level agreement including, but not limited to, deployment of network engineers, re-provisioning equipment, identifying rogue elements, etc.

4. A method for re-provisioning a network infrastructure in an attempt to avoid a breach of a service level agreement, comprising:
-
receiving a plurality of measured component metrics, each of the measured component metrics having a weighted contribution to a service level metric;
applying a time series analysis to each of the plurality of measured component metrics so as to determine a predicted next sample for each of the plurality of measured component metrics;
combining each of the predicted next samples, based on the weighted contribution of each component metric to the service level metric, in order to determine an estimate of the service level metric during a prediction interval;
determining a probability of whether the estimate of the service level metric will exceed a threshold value defined by the service level agreement; and
if the probability exceeds a determined value, re-provisioning the network infrastructure prior to occurrence of the prediction interval. - View Dependent Claims (5, 6)
