Abstract

A method and system for route transforming by a network device implements a content centric networking (CCN) gateway or CCN router, where the CCN gateway or CCN router is part of a CCN network. The method to handle a first CCN reply before forwarding a second CCN reply in the CCN network. The method includes receiving the first CCN reply including a second CCN Name, applying a transform configuration to the second CCN Name to obtain CCN reply data, and generating a second CCN reply using the CCN reply data and a first CCN Name from a pending interest table (PIT) entry for the first CCN Name.

Claims

1. A method for route transforming by a network device implementing a content centric networking (CCN) gateway or CCN router, where the CCN gateway or CCN router is part of a CCN network, the method to handle a first CCN reply before forwarding a second CCN reply in the CCN network, the method comprising:

receiving the first CCN reply including a second CCN Name;

applying a transform configuration to the second CCN Name to obtain CCN reply data; and

generating the second CCN reply using the CCN reply data and a first CCN Name from a pending interest table (PIT) entry for the first CCN Name.

2. The method of claim 1, further comprising:

determining whether a PIT entry exists for the second CCN Name.

3. The method of claim 1, further comprising:

forwarding the second CCN reply according to the PIT entry for the first CCN Name.

4. The method of claim 1, wherein the PIT entry associates the first CCN Name, a transform configuration, and the second CCN Name.

5. The method of claim 1, the method further to transform the first CCN Name in a CCN request before forwarding in the CCN network, the method further comprising:

receiving a first CCN request including the first CCN Name, the first CCN Name including a route transformer identifier, the route transformer identifier to identify a first process for modifying the first CCN Name; and

generating a modified first CCN Name by removing the route transformer identifier from the first CCN Name.

6. A network device to implement a method for route transforming, the network device in a content centric networking (CCN) gateway or CCN router, where the CCN gateway or CCN router is part of a CCN network, the method to handle a first CCN reply before forwarding a second CCN reply in the CCN network, the network device comprising:

a non-transitory computer-readable medium having stored therein a route transforming module; and

a processor coupled to the non-transitory computer-readable medium, the processor configured to execute the route transforming module, the route transforming module configured to receive the first CCN reply including a second CCN Name, to apply a transform configuration to the second CCN Name to obtain CCN reply data, and generate the second CCN reply using the CCN reply data and a first CCN Name from a pending interest table (PIT) entry for the first CCN Name.

7. The network device of claim 6, wherein the route transforming module is further configured to determine whether a PIT entry exists for the second CCN Name.

8. The network device of claim 6, wherein the route transforming module is further configured to forwarding the second CCN reply according to the PIT entry for the first CCN Name.

9. The network device of claim 6, wherein the PIT entry associates the first CCN Name, a transform configuration, and the second CCN Name.

10. The network device of claim 6, the network device further configured to transform the first CCN Name in a CCN request before forwarding in the CCN network, by receiving a first CCN request including the first CCN Name, the first CCN Name including a route transformer identifier, the route transformer identifier to identify a first process for modifying the first CCN Name, and generating a modified first CCN Name by removing the route transformer identifier from the first CCN Name.

11. A computing device to execute a plurality of virtual machines for implementing network function virtualization (NFV), wherein a virtual machine from the plurality of virtual machines is configured to implement a method for route transforming, the computing device in a content centric networking (CCN) gateway or CCN router, where the CCN gateway or CCN router is part of a CCN network, the method to handle a first CCN reply before forwarding a second CCN reply in the CCN network, the computing device comprising:

a non-transitory computer-readable medium having stored therein a route transforming module; and

a processor coupled to the non-transitory computer-readable medium, the processor configured to execute the virtual machine, the virtual machine configured to execute the route transforming module, the route transforming module configured to receive the first CCN reply including a second CCN Name, to apply a transform configuration to the second CCN Name to obtain CCN reply data, and generate the second CCN reply using the CCN reply data and a first CCN Name from a pending interest table (PIT) entry for the first CCN Name.

12. The computing device of claim 11, wherein the route transforming module is further configured to determine whether a PIT entry exists for the second CCN Name.

13. The computing device of claim 11, wherein the route transforming module is further configured to forwarding the second CCN reply according to the PIT entry for the first CCN Name.

14. The computing device of claim 11, wherein the PIT entry associates the first CCN Name, a transform configuration, and the second CCN Name.

15. The computing device of claim 11, the computing device further configured to transform the first CCN Name in a CCN request before forwarding in the CCN network, by receiving a first CCN request including the first CCN Name, the first CCN Name including a route transformer identifier, the route transformer identifier to identify a first process for modifying the first CCN Name, and generating a modified first CCN Name by removing the route transformer identifier from the first CCN Name.

16. A control plane device configured to implement a control plane of a software defined networking (SDN) network including a plurality of network devices forming a content centric network, the control plane device implementing a method for route transforming, the control plane device in communication with a content centric networking (CCN) gateway or CCN router, where the CCN gateway or CCN router is part of a CCN network, the method to handle a first CCN reply before forwarding a second CCN reply in the CCN network, the control plane device comprising:

a non-transitory computer-readable medium having stored therein a route transforming module; and

a processor coupled to the non-transitory computer-readable medium, the processor configured to execute the route transforming module, the route transforming module configured to receive the first CCN reply including a second CCN Name, to apply a transform configuration to the second CCN Name to obtain CCN reply data, and generate the second CCN reply using the CCN reply data and a first CCN Name from a pending interest table (PIT) entry for the first CCN Name.
