Abstract

An intelligent Internet Protocol (IP) resolver can be configured to receive a domain name service (DNS) request from a node of an external network to resolve a domain name for a content provider accessed via an autonomous network. The intelligent IP resolver can also be configured to determine an entry point into the autonomous network for traffic originating from a mobile device identified in the DNS request. The intelligent IP resolver can further be configured to generate a DNS answer that identifies a node of the content provider. The node of the content provider can be determined based on the entry point of the autonomous network.

Claims

1. An intelligent Internet Protocol (IP) resolver implemented on one or more computing devices having machine readable instructions, the intelligent IP resolver being configured to:

receive a domain name service (DNS) request from a node of an external network to resolve a domain name for a content provider accessed via an autonomous network;

determine an entry point into the autonomous network for traffic originating from a mobile device identified in the DNS request; and

generate a DNS answer that identifies a node of the content provider, wherein the node of the content provider is determined based on the entry point of the autonomous network.

2. The intelligent IP resolver of claim 1, wherein the intelligent IP resolver is further configured to provide a control plane message to a network node of the external network to determine the entry point of the autonomous network.

3. The intelligent IP resolver of claim 2, wherein the entry point of the autonomous network comprises a gateway to the autonomous network.

4. The intelligent IP resolver of claim 3, wherein the external network is a mobile network and the gateway comprises a packet network gateway.

5. The intelligent IP resolver of claim 4, wherein the mobile network comprises at least one of a Long Term Evolution (LTE) network, a 3GPP network and a 3GPP2 network.

6. The intelligent IP resolver of claim 1, wherein the intelligent IP resolver is further configured to execute a network routing algorithm that employs an IP address of a node of the entry point of the autonomous network as an estimate for a location of the mobile device to determine the node of the content provider.

7. The intelligent IP resolver of claim 1, wherein the intelligent IP resolver is further configured to execute a traceroute function toward the mobile device to determine the entry point of the autonomous network.

8. The intelligent IP resolver of claim 7, wherein the entry point of the autonomous network comprises a gateway to the autonomous network identified in the traceroute function.

9. The intelligent IP resolver of claim 8, wherein the external network comprises a WiFi network.

10. An autonomous network comprising:

a plurality of entry points to the autonomous network, wherein each entry point is coupled to a corresponding external network of a plurality of external networks; and

an intelligent IP resolver configured to;

receive a domain name service (DNS) request for a content provider comprising a plurality of nodes, wherein the DNS request identifies a mobile device operating on an external network; and

select a node of the content provider based on a particular entry point of the plurality of entry points in response to the DNS request, wherein traffic from the mobile device flows through the particular entry point into the autonomous network.

11. The autonomous network of claim 10, wherein the intelligent IP resolver is further configured to provide an answer to the DNS request that identifies the selected node of the content provider.

12. The autonomous network of claim 10, wherein each entry point of the plurality of entry points comprises a gateway.

13. The autonomous network of claim 10, wherein the intelligent IP resolver is further configured to determine the particular entry point of the plurality of entry points based on a control message provided to a network node.

14. The autonomous network of claim 10, wherein the intelligent IP resolver is further configured to determine the particular entry point of the plurality of entry points based on a traceroute function toward the mobile device.

15. The autonomous network of claim 10, wherein the content provider is configured to provide requested content to the mobile device in response to a content request directed to the selected node of the content provider.

16. A method comprising:

receiving a domain name service (DNS) request from a node of an external network to resolve a domain name for a content provider operating on an autonomous network;

determining whether network architecture and control plane interface information are known for the autonomous network;

identifying an entry point into the autonomous network for traffic originating from a mobile device identified in the DNS request, in response to the determination of whether the network architecture and the control plane interface information are known; and

determine an Internet Protocol (IP) address for a node of the content provider based on the entry point into the autonomous network.

17. The method of claim 16, further comprising generating a traceroute function toward the mobile device, wherein the entry point to the autonomous network comprises a gateway to the autonomous network identified by the traceroute function.

18. The method of claim 16, further comprising generating a control plane message comprising a query to a policy and charging function, wherein the entry point to the autonomous network comprises a packet node gateway identified in response to the query.

19. The method of claim 16, further comprising providing a DNS answer to the DNS request that identifies the IP address of the node of the content provider.

20. The method of claim 16, wherein the DNS request is received from a Long Term Evolution (LTE) network, a 3GPP network or a 3GPP2 network.
