Abstract

A system for collecting and aggregating data from network entities for a data consuming application is described. The system includes a data collector layer to receive network flow information from the network entities and to produce records based on the information. The system also includes a flow aggregation layer fed from the data collection layer and coupled to a storage device. The flow aggregation layer receiving records produced by the data collector layer and aggregates received records. The system can also include an equipment interface layer coupled to the data collector layer and a distribution layer to obtain selected information stored in the storage device and to distribute the select information to a requesting, data consuming application.

Claims

1. A computer implemented method comprising

providing a subscriber with a service having a first characteristic,

observing at the network, that the provided service to the subscriber has a second characteristic;

and

billing the subscriber for the service having the second characteristic rather than for the service having the first characteristic.

2. The method of claim 1 wherein observing further comprises:

determining at the network that resources are not available for providing the first level of service; and

, in response to said determination,

providing a second level service.

3. The method of claim 2 wherein providing the second level of service further comprises:

reassessing and redefining the deployed service.

4. The method of claim 3 wherein the process observes whether reassessment and redefining of the deployed policy was successful.

5. The method of claim 1 further comprising:

determining whether there has been packet loss; and

wherein determining packet loss includes;

deploying a packet detector monitor in the network to generate network accounting records that can be used to determine packet loss.

6. The method of claim 1 wherein the providing further comprises:

establishing a differentiate services policy that is decomposed into a collection of configurations and deployed in a network.

7. The method of claim 1 wherein the providing further comprises:

deploying the configurations to a collection of routers or switches that the customer would have access to in the network.

8. The method of claim 1 wherein observing observes a large number of network flows.

9. The method of claim 8 wherein observing further comprises:

using an accounting process that produces information at a granularity level at which the policies are actually deployed.

10. The method of claim 9 wherein the policies are deployed at source and destination IP address, protocol and/or destination port level.
