Abstract

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for determining rogue traffic using flow statistics and a list of authorized media engines. A system configured according to this disclosure receives data associated with a group of packets in a media queue, such as the source network address where the packets originated, the destination network address for the packets, and an indication of an associated queue for the packets. The system then verifies the data received by comparing the source network address to a list of network addresses of known media engines. The system further verifies that the indication of an associated queue for the packets is correct for the packets. Should the system detect failure in the verification of known media engines or the verification of indication of associated queues, the system generates a notification.

Claims (34)

1. A method comprising:

receiving data associated with a plurality of packets in a media queue, the data comprising a source network address, a destination network address, and an indication of an associated queue for the plurality of packets; and

based on the data, determining, via a processor, whether at least one of the source network address is a prohibited network address and the indication of the associated queue is correct for the plurality of packets.

2. The method of claim 1 , further comprising generating a notification when at least one of the source network address is the prohibited network address and the indication of the associated queue is not correct for the plurality of packets.

3. The method of claim 2 , wherein the determining step comprises:

verifying, via a first test, the data to a list of network addresses of known media engines; and

verifying, via a second test, that the indication of the associated queue is correct for the plurality of packets.

4. The method of claim 3 , wherein the notification is generated when at least one of the first test and the second test fails.

5. The method of claim 3 , wherein the first test and the second test are performed one of in sequence and simultaneously.

6. The method of claim 2 , wherein the determining step comprises comparing at least one of the source network address and the destination network address with a list of network addresses of known media engines.

7. The method of claim 2 , further comprising using the notification to generate a report.

8. The method of claim 2 , further comprising communicating the notification to an administrator.

9. The method of claim 8 , wherein the notification is communicated via an email.

10. The method of claim 1 , wherein the data further comprises at least one of a modulation type, a protocol, a bandwidth size, a data size, and a transmission duration.

11. A system comprising:

a processor; and

a computer-readable storage medium having stored therein instructions which, when executed by the processor, perform operations comprising:

receiving data associated with a plurality of packets in a media queue, wherein the data comprises a source network address, a destination network address, and an indication of an associated queue for the plurality of packets;

performing a test to verify that at least one of the source network address is a prohibited network address and the indication of the associated queue is correct for the plurality of packets;

generating a notification when the test fails.

12. The system of claim 11 , wherein performing a test comprises verifying the data to a list of network addresses of known media engines.

13. The system of claim 11 , wherein the test comprises a first test verifying the data to the list of network addresses of known engines and a second test to verify that the indication of the associated queue is correct for the plurality of packets.

14. The system of claim 13 , wherein the first test and the second test are performed one of in sequence and simultaneously.

15. The system of claim 11 , wherein the data further comprises at least one of a modulation type, a protocol, a bandwidth size, a data size, and a transmission duration.

16. The system of claim 11 , wherein the computer-readable storage medium stores additional instructions which, when executed by the processor, result in an operation further comprising generating a report based on the notification.

17. A computer-readable storage device having stored therein instructions which, when executed by a processor, cause the processor to perform operations comprising:

identifying at least one of a source network address associated with a plurality of packets in a media queue and an indication of an associated queue for the plurality of packets;

comparing the source network address with a list of network addresses of known media engines; and

generating a notification based on a determination that at least one of the source network address is a prohibited network address and the indication of the associated queue is not correct.

18. The computer-readable storage device of claim 17 , wherein the determination is based on at least one of a modulation type, a protocol, a bandwidth size, a data size, and a transmission duration.

19. The computer-readable storage device of claim 17 , wherein comparing the source network address comprises a first test, and wherein the determination that the indication of the associated queue is not correct is based on a second test for verifying the indication.

20. The computer-readable storage device of claim 19 , storing additional instructions which, when executed by the processor, result in operations further comprising:

identifying a destination network address; and

generating a report based on the notification, wherein the determination that the indication of the associated queue is not correct is at least partly based on the destination network address.
