Abstract

Claims (24)

1. A method comprising:

identifying, by one or more processors, a plurality of candidate communication routes from a first networking node toward a second networking node, at least a first one of the candidate communication routes comprising one or more virtual network tunnels for use by traffic aggregated from multiple sources, the one or more virtual network tunnels each built between respective peer nodes over an underlying network infrastructure;

determining, by the one or more processors, a plurality of ratings corresponding respectively to individual routes of the plurality of candidate communication routes, each rating of the plurality based at least in part on a plurality of factors applicable to the respective individual route, including a security rating, wherein a respective security rating indicates a respective level of security risk for each of the plurality of candidate communication routes; and

selecting, by the one or more processors, one or more communication routes from the plurality of candidate communication routes based on the plurality of ratings, wherein the selected one or more communication routes are used to communicate data from the first networking node toward the second networking node.

2. The method of claim 1 , wherein the first networking node is a virtual network first endpoint device (EPD).

3. The method of claim 2 , wherein the second networking node is a virtual network second EPD.

4. The method of claim 3 , wherein at least one tunnel of the one or more virtual network tunnels extends from the virtual network first EPD to the virtual network second EPD.

5. The method of claim 4 , wherein at least a second one of the candidate communication routes traverses a wide area network path determined at least in part by standard Internet Protocol routing.

6. The method of claim 4 , wherein the at least one tunnel is associated with a first virtual interface at the virtual network first EPD and with a second virtual interface at the virtual network second EPD.

7. The method of claim 6 , wherein the first virtual interface and the second virtual interface pass traffic between a first local area network coupled to the first networking node and a second local area network coupled to the second networking node.

8. The method of claim 7 , wherein the at least one tunnel comprises a plurality of parallel virtual network tunnels that are concurrently active.

9. The method of claim 1 , wherein the at least a first one of the candidate communication routes comprises a first route that connects the first networking node to a virtual network first access point via a first tunnel of the one or more virtual network tunnels, and a second route that connects the first networking node to a virtual network second access point via a second tunnel of the one or more virtual network tunnels.

10. The method of claim 9 , wherein a third tunnel of the one or more virtual network tunnels connects the first networking node to the virtual network first access point, the first and third tunnels concurrently active, and wherein a fourth tunnel of the one or more virtual network tunnels connects the first networking node to the virtual network second access point, the second and fourth tunnels concurrently active.

11. The method of claim 10 , wherein the first and third tunnels are each associated with the first route, and the second and fourth tunnels are each associated with the second route.

12. The method of claim 11 , wherein the first route aggregates traffic across the first and third tunnels.

13. The method of claim 10 , wherein the at least a first one of the candidate communication routes further comprises a third route associated with the third tunnel and a fourth route associated with the fourth tunnel.

14. The method of claim 1 , wherein the plurality of factors comprises a data type for a particular data flow.

15. The method of claim 1 , wherein the plurality of factors comprises at least one of a current or a historical latency for a particular candidate communication route or a network segment thereof.

16. The method of claim 1 , wherein one or more of the candidate communication routes traverse a firewall perimeter located in a cloud.

17. The method of claim 1 , wherein the second networking node comprises an EPD connected to a cloud service provider partner organization, the EPD configured to connect via virtual network connections to a plurality of remote user locations.

18. The method of claim 1 , wherein the first networking node is a virtual network access point.

19. The method of claim 1 , wherein the one or more virtual network tunnels comprises a plurality of virtual network tunnels joined end-to-end.

20. The method of claim 1 , wherein the one or more virtual network tunnels comprises and end-to-end tunnel connecting the first and second networking nodes, the end-to-end tunnel routed within a plurality of intermediate tunnels joining intermediate peer nodes between the first and second networking nodes.

21. The method of claim 1 , further comprising determining that none of the plurality of candidate communication routes have an acceptable rating for the given traffic flow, and therefore selecting instead to build a new virtual network tunnel to a selected virtual network access point and select a route including the new virtual network tunnel for the given traffic flow.
