Abstract

Systems and methods are described for effectively managing and maintaining a communication network by monitoring communications to detect a loop condition, and effectively route the communication to one or more destinations known to reduce or eliminate the occurrence of a looping condition.

First claim

The invention claimed is:

1. A system comprising:
a first computing device and a second computing device,
wherein the first computing device comprises:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the first computing device to:
receive, from the second computing device and via a network, a communication request addressed to a destination address;
determine that a quantity of instances the communication request was routed through a node on the network satisfies a threshold;
after determining that the quantity of instances satisfies the threshold:
cause suppression of the received communication request; and
add the destination address to a list of addresses associated with looping conditions; and

use the list of addresses to process one or more subsequent communication requests, and

wherein the second computing device is configured to send the communication request.

2. The system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression further based on a determination that the received communication request was received as a result of a looping condition.

3. The system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression further based on a determination that an originating address, associated with the received communication request, is associated with one or more looping customers.

4. The system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression further based on a determination that a frequency of communication requests, originating from an originating address associated with the received communication request and addressed for the destination address, satisfies a threshold.

5. The system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression of the received communication request by:
modifying a header of the received communication request to include a data field comprising a looping identifier indicating that the received communication request was sent by a looping customer; and
routing, based on the looping identifier, the received communication request.

6. The system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression of the received communication request by rejecting the received communication request.

7. The system of claim 1 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression of the received communication request by:
determining that an originating address, associated with the received communication request, is associated with one or more looping customers; and
determining a route to the destination address via another computing device not associated with the one or more looping customers.

8. A system comprising:
a first computing device and a second computing device,
wherein the first computing device comprises:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the first computing device to:
receive, via a network, a communication request from an originating address;
determine that a quantity of instances the communication request was routed through a node on the network satisfies a threshold;

after determining that the quantity of instances satisfies the threshold:
cause suppression of the received communication request; and
add the originating address to a list of addresses associated with looping conditions; and
use the list of addresses to process one or more subsequent communication requests, and

wherein the second computing device is configured to send the communication request.

9. The system of claim 8 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression further based on a determinization that the received communication request was received as a result of a looping condition.

10. The system of claim 8 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression further based on a determination that the originating address is associated with one or more looping customers.

11. The system of claim 8 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression further based on a determination that a frequency of communication requests, originating from the originating address, satisfies a threshold.

12. The system of claim 8 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression of the received communication request by:
modifying a header of the received communication request to include a data field comprising a looping identifier indicating that the received communication request was sent by a looping customer; and
routing, based on the looping identifier, the received communication request.

13. The system of claim 8 , wherein the instructions, when executed by the one or more processors, cause the first computing device to cause the suppression of the received communication request by rejecting the received communication request.

14. One or more non-transitory computer-readable media storing instructions that, when executed, cause:
receiving, via a network, a communication request addressed to a destination address;
determining that a quantity of instances the communication request was routed through a node on the network satisfies a threshold;
after the determining that the quantity of instances satisfies the threshold:
causing suppression of the received communication request; and
adding the destination address to a list of addresses associated with looping conditions; and

using the list of addresses to process one or more subsequent communication requests.

15. The one or more non-transitory computer-readable media of claim 14 , wherein the instructions, when executed, cause the suppression further based on a determination that the received communication request was received as a result of a looping condition.

16. The one or more non-transitory computer-readable media of claim 14 , wherein the instructions, when executed, cause the suppression further based on a determination that an originating address, associated with the received communication request, is associated with one or more looping customers.

17. The one or more non-transitory computer-readable media of claim 14 , wherein the instructions, when executed, cause the suppression further based on a determination that a frequency of communication requests, originating from an originating address associated with the received communication request and addressed for the destination address, satisfies a threshold.

18. The one or more non-transitory computer-readable media of claim 14 , wherein the instructions, when executed, cause the suppression of the received communication request by causing:
modifying a header of the received communication request to include a data field comprising a looping identifier indicating that the received communication request was sent by a looping customer; and
routing, based on t
