Abstract

An apparatus and method for measurement, analysis, and optimization of content delivery over a communications network is presented. In one embodiment, the apparatus detects data packets en route over a communications network. The detected data packets are read by the apparatus, combined into application messages, and further combined into user centric events. The events are analyzed to identify metrics and statistics relating to the delivery of content over a communications network and the experience of the end user. The metrics and statistics are saved in a data storage area. When the metrics exceed a configurable threshold, the apparatus provides real-time notification of content delivery problems or end user experience problems. Alternatively, the system can take action to proactively prevent anticipated content delivery problems or end user experience problems.

Claims

1. A method for aggregating data relating to measuring, analyzing, and optimizing the delivery of content over a communications network, comprising:

receiving an application message from a transmission control protocol layer;

parsing the application message to identify an associated application;

routing the application message to an application decoding layer for the associated application;

combining a plurality of application messages at the application decoding layer into a data object comprising a plurality of data elements; and

writing the data object to a data cache, wherein the data plurality of data elements represent real time metrics relating to the delivery of content over a communications network.

2. The method of claim 1, further comprising periodically migrating a plurality of data objects from the data cache to a temporary storage area.

3. The method of claim 2, further comprising periodically adding data objects from the temporary storage area to a long term storage area having an initial data size, wherein the data size of the long term storage area after the addition is less than the data size of the temporary storage area and the initial data size of the long term storage area combined.

4. The method of claim 4, further comprising:

adding data objects exclusively to a first long term storage area during a first time period;

receiving an indicator to switch long term storage areas;

purging a second long term storage area; and

adding data objects exclusively to the second long term storage area during a second time period.

5. The method of claim 4, further comprising:

receiving an indicator to switch long term storage areas;

purging the first long term storage area; and

adding data objects exclusively to the first long term storage area during a third time period.

6. The method of claim 5, further comprising:

receiving an indicator to switch long term storage areas;

purging the second long term storage area; and

adding data objects exclusively to the second long term storage area during a fourth time period.

7. A method for aggregating data relating to measuring, analyzing, and optimizing the delivery of content over a communications network, comprising:

receiving an application message from a transmission control protocol layer;

parsing the application message to identify an associated application;

routing the application message to an application decoding layer for the associated application;

combining a plurality of application messages at the application decoding layer into a data object comprising a plurality of data elements;

providing the data object to a root analyzer; and

parsing the data object at the root analyzer to determine a type for the data object.

8. The method of claim 7, further comprising routing the data object from the root analyzers to a sub-analyzer for the identified type of data object for storage in one or more data storage areas.

9. The method of claim 8, further comprising at the sub-analyzer:

parsing the data object to identify a plurality of data elements;

identifying a type for each of the identified data elements;

storing a data element in a data storage area associated with the identified type for the data element.

10. The method of claim 9, wherein discrete data storage areas are used to separately store discrete types of data elements.
