Abstract

A method for operating a communication system is provided. The method includes monitoring traffic within a communication network to determine a traffic volume, and determining a routing table update rate based on the traffic volume. The method also includes receiving a routing table update, and updating a routing table using the routing table update at a time based on the routing table update rate.

Claims

1. A method for operating a communication system comprising:

monitoring traffic within a communication network to determine a traffic volume;

determining a routing table update rate based on the traffic volume;

receiving a routing table update;

determining a delay period based on the routing table update rate;

determining a time of a previous update of the routing table;

adding the delay period to the time of the previous update of the routing table to identify an update time; and

updating a routing table using the routing table update at the update time.

2. The method of claim 1 further comprising:

translating the routing table update from a first format into a second format.

3. The method of claim 1 wherein the traffic within the communication network is monitored at a gateway.

4. The method of claim 1 wherein the traffic within the communication network is monitored at a session border controller.

5. The method of claim 1 wherein the routing table update is configured to trigger an update of a subset of the routing table.

6. The method of claim 1 wherein the routing table update is configured to trigger an update of all of the routing table.

7. A communication system comprising:

a remote processing system coupled to a communication network, configured to determine a traffic volume within the communication network, determine a routing table update rate based on the traffic volume, receive a routing table update, determine a delay period based on the routing table update rate, determine a time of a previous update of the routing table, add the delay period to the time of the previous update of the routing table to identify an update time, and update a routing table using the routing table update; and

a remote management system coupled to the remote processing system, configured to receive the routing table update rate from the remote processing system, receive a routing table update, and transmit the routing table update to the remote processing system at the update time.

8. The communication system of claim 7,

wherein the remote management system is configured to receive a plurality of routing table updates, combine the plurality of routing table updates into a single combined routing table update, and transfer the combined routing table update to the remote processing system at a time based on the routing table update rate.

9. The communication system of claim 7,

wherein the remote management system is configured to translate the routing table update from a first format into a second format.

10. The communication system of claim 7 wherein the traffic within the communication network is monitored at a gateway.

11. The communication system of claim 7 wherein the traffic within the communication network is monitored at a session border controller.

12. The communication system of claim 7 wherein the remote processing system is configured to update a subset of the routing table.

13. The communication system of claim 7 wherein the remote processing system is configured to update all of the routing table.

14. The communication system of claim 7,

wherein the remote processing system is configured to transmit a control signal to the remote management system when the routing table may be updated.

15. The communication system of claim 14,

wherein the remote management system is configured to transfer a routing table update to the remote processing system when the control signal is asserted.
