Abstract

Claims (36)

1 . A method comprising:

collecting, by a first network controller at a point of presence, traffic data from a network switch;

storing the traffic data in a first feedback database associated with a first network controller;

generating a control packet containing the traffic data from the first feedback database;

transmitting the control packet to a second network controller using one or more communication links;

receiving the control packet by the second network controller;

updating a second feedback database associated with the second network controller with the traffic data from the received control packet;

providing a routing decision using at least the second feedback database; and

directing a second switch to route data packets according to the routing decision.

2 . The method of claim 1 , wherein the one or more communication links comprise an in-band communication link.

3 . The method of claim 1 , wherein the control packet includes a timestamp indicating when the traffic data was collected.

4 . The method of claim 1 , wherein the traffic data comprise metrics selected from the group consisting of latency, packet loss, throughput, and link utilization.

5 . The method of claim 1 , further comprising prioritizing a transmission of the control packet based on an urgency of the traffic data.

6 . The method of claim 1 , wherein the first feedback database is configured on multiple physical locations.

7 . The method of claim 1 , wherein the control packet comprises an identifier for the point of presence from which the traffic data was collected.

8 . The method of claim 1 , wherein the control packet is transmitted using a multicast protocol.

9 . The method of claim 1 , wherein the second network controller is configured to autonomously adjust routing policies based on the received control packets.

10 . The method of claim 1 , further comprising synchronizing the first database and the second database.

11 . A non-transitory machine readable medium storing a controller program which when executed by a processor, the controller program comprising sets of instructions for:

collecting, by a first network controller at a point of presence, traffic data from a network switch;

storing the traffic data in a first feedback database associated with a first network controller;

generating a control packet containing the traffic data from the first feedback database;

transmitting the control packet to a second network controller using one or more communication links;

receiving the control packet by the second network controller;

updating a second feedback database associated with the second network controller with the traffic data from the received control packet;

providing a routing decision using at least the second feedback databases; and

directing a second switch to route data packets according to the routing decision.

12 . The non-transitory machine readable medium of claim 11 , wherein the one or more communication links comprise an in-band communication link.

13 . The non-transitory machine readable medium of claim 11 , wherein the control packet includes a timestamp indicating when the traffic data was collected.

14 . The non-transitory machine readable medium of claim 11 , wherein the traffic data comprise metrics selected from the group consisting of latency, packet loss, throughput, and link utilization.

15 . The non-transitory machine readable medium of claim 11 , wherein controller program further comprises instructions for prioritizing a transmission of the control packet based on an urgency of the traffic data.

16 . The non-transitory machine readable medium of claim 11 , wherein the first feedback database is configured on multiple physical locations.

17 . The non-transitory machine readable medium of claim 11 , wherein the control packet comprises an identifier for the point of presence from which the traffic data was collected.

18 . The non-transitory machine readable medium of claim 11 , wherein the control packet is transmitted using a multicast protocol.

19 . The non-transitory machine readable medium of claim 11 , wherein the second network controller is configured to autonomously adjust routing policies based on the received control packets.

20 . The non-transitory machine readable medium of claim 11 , further comprising synchronizing the first database and the second database.
