Abstract

Methods and systems are described for incrementally resolving a host name to a network address. In one aspect, the method includes receiving, by a path node in a network path to a destination node, a packet including a name corresponding to a portion of a network address. The method also includes determining the portion of the network address corresponding to the name. The method further includes determining a network interface of the path node based on the portion of the network address. The method still further includes transmitting the packet via the determined network interface to a next node in the network path to the destination node.

Claims

1. A method for incrementally resolving a host name to a network address, the method comprising:

receiving, by a path node in a network path to a destination node, a packet including a name corresponding to a portion of a network address;

determining the portion of the network address corresponding to the name;

determining, based on the portion of the network address, a network interface of the path node; and

transmitting the packet via the determined network interface to a next node in the network path to the destination node,

wherein at least one of the preceding actions is performed on at least one electronic hardware component.

2. The method of claim 1 wherein the network address is an internet protocol (IP) address and the name corresponds to a hierarchical portion of the internet protocol address.

3. The method of claim 1 wherein the packet includes a first header including type bits indicating that a name is included in the packet.

4. The method of claim 3 wherein the packet includes a name header including the name.

5. The method of claim 3 wherein the packet includes a payload area including the name.

6. The method of claim 1 further comprising detecting the name in the packet;

and

in response to detecting the name, identifying the position of the corresponding portion of the network address within the network address.

7. The method of claim 6 wherein detecting the name in the packet is based on a packet schema.

8. The method of claim 1 wherein determining the portion of the network address corresponding to the name includes querying a network directory service node configured to resolve the name to the portion of the network address.

9. The method of claim 8 wherein the network directory service node represents at least a portion of a domain identified by the name, when the name is a root domain portion of a network directory service name.

10. The method of claim 1 wherein determining a network interface is based on at least one of a routing policy and a routing table.

11. The method of claim 1 wherein the name is a geospatial name identifying a name geospatial region.

12. The method of claim 11 wherein the geospatial name is associated with a domain having a corresponding domain geospatial region at least partially present in the name geospatial region.

13. A system for incrementally resolving a host name to a network address, the system comprising:

means for receiving, by a path node in a network path to a destination node, a packet including a name corresponding to a portion of a network address;

means for determining the portion of the network address corresponding to the name;

means for determining a network interface of the path node based on the portion of the network address; and

means for transmitting the packet via the determined network interface to a next node in the network path to the destination node,

wherein at least one of the means includes at least one electronic hardware component.

14. A system for incrementally resolving a host name to a network address, the system comprising system components including:

a packet detector component, in a path node in a network path to a destination node, configured to receive a packet including a name corresponding to a portion of a network address;

a resolver component configured to determine the portion of the network address corresponding to the name;

a forwarding engine component configured to determine a network interface of the path node based on the portion of the network address; and

a network interface component configured to transmit the packet via the determined network interface to a next node in the network path to the destination node,

wherein at least one of the system components includes at least one electronic hardware component.

15. The system of claim 14 wherein the network address is an internet protocol (IP) address and the name corresponds to a hierarchical portion of the internet protocol address.

16. The system of claim 14 wherein the packet detector component is configured to receive the packet including a first header including type bits indicating that a name is included in the packet.

17. The system of claim 16 wherein the packet detector component is configured to receive the packet including a name header including the name.

18. The system of claim 16 wherein the packet detector component is configured to receive the packet including a payload area including the name.

19. The system of claim 14 wherein the resolver component is configured to detect the name in the packet, and, in response to detecting the name, identify the position of the corresponding portion of the network address within the network address.

20. The system of claim 19 wherein the resolver component is configured to detect the name in the packet based on a packet schema.

21. The system of claim 14 wherein the resolver component is configured to query a network directory service node configured to resolve the name to the portion of the network address.

22. The system of claim 21 wherein the network directory service node represents at least a portion of a domain identified by the name, when the name is a root domain portion of a network directory service name.

23. The system of claim 14 wherein the forwarding engine component is configured to determine a network interface is based on at least one of a routing policy and a routing table.

24. The system of claim 14 wherein the name is a geospatial name identifying a name geospatial region.

25. The system of claim 24 wherein the geospatial name is associated with a domain having a corresponding domain geospatial region at least partially present in the name geospatial region.

26. A computer readable medium storing a computer program, executable by a machine, for incrementally resolving a host name to a network address, the computer program comprising executable instructions for:

receiving, by a path node in a network path to a destination node, a packet including a name corresponding to a portion of a network address;

determining the portion of the network address corresponding to the name;

determining a network interface of the path node based on the portion of the network address; and

transmitting the packet via the determined network interface to a next node in the network path to the destination node.
