5. The method of processing statistics in integrated deep packet inspection routers, according to claim 4, wherein:

getting the first entity, determining that the application statistic has changed for the first entity, getting application statistics for the first application of the first entity, determining that the application statistics for the first application of the first entity have changed, and processing the application statistics for the first application of the first entity, occur first;

determining that the first entity has the next application of the first entity, getting application statistics for the next application of the first entity, determining that the application statistics for the next application of the first entity have changed, and processing the application statistics for the next application of the first entity, occur second;

determining that there is the next entity, getting the next entity, determining that the application statistic has changed for the next entity, getting the application statistics for the first application of the next entity, determining that the application statistics for the first application of the next entity have changed, and processing the application statistics for the first application of the next entity, occur third; and

determining that the next entity has the next application, getting application statistics for the next application of the next entity, determining that the application statistics for the next application of the next entity have changed, and processing the application statistics for the next application of the next entity, occur fourth.

6. The method of processing statistics in integrated deep packet inspection routers, according to claim 1, wherein processing the application statistics includes at least one of allocating resources to internally enable collection of the application statistics, incrementing the application statistics internally in allocated resources, storing the application statistics internally, and exporting the application statistics.

7. The method of processing statistics in integrated deep packet inspection routers, according to claim 1, wherein the first entity is selected from the list consisting of a subscriber, an end user, equipment of a subscriber, equipment of an end user, a group of subscribers, a group of end users, equipment of a group of subscribers, and equipment of a group of end users.

8. The method of processing statistics in integrated deep packet inspection routers, according to claim 7, wherein the entity is attached to a common access device.

9. The method of processing statistics in integrated deep packet inspection routers, according to claim 8, wherein the common access device is selected from the list consisting of a DSLAM, a router, an Ethernet switch, a BRAS, and a network.

10. The method of processing statistics in integrated deep packet inspection routers, according to claim 1, wherein the first application of the first entity is selected from the list consisting of a protocol used to send data, application that uses a protocol, and a grouping of applications.

11. The method of processing statistics in integrated deep packet inspection routers, according to claim 10, wherein the first application of the first entity is selected from the list consisting of TCP, HTTP, video, VoIP, a game, a themed group of applications, and a group of gaming applications.

12. The method of processing statistics in integrated deep packet inspection routers, according to claim 1, wherein the processing includes at least one of processing a regular output record, processing a cumulative output record, sending a record, writing a copy of a record, and modifying a record.

13. The method of processing statistics in integrated deep packet inspection routers, according to claim 1, further comprising defining at least one application statistics filter.
