Abstract

A method provides 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 transforms a CCN Name in a CCN request before forwarding in the CCN network. The method includes receiving a first CCN request including a first CCN Name, the first CCN Name including a route transformer identifier, generating a modified first CCN Name by removing the route transformer identifier from the first CCN Name, generating a second CCN Name from the modified first CCN Name; and generating a second CCN request including the second 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 transform a CCN Name in a CCN request before forwarding in the CCN network, the method comprising:

receiving a first CCN request including a 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;

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

generating a second CCN Name from the modified first CCN Name using the first process;

generating a second CCN request including the second CCN Name; and

transmitting the second CCN request toward a destination in the CCN network.

2. The method of claim 1, the method further comprising:

generating a pending interest table (PIT) entry for the first CCN Name from the first CCN Request.

3. The method of claim 2, further comprising:

generating a PIT entry for the second CCN request that associates the first CCN Name, a transform configuration, and the second CCN Name.

4. The method of claim 3, wherein the transform configuration identifies a second process for generating the first CCN Name from the second CCN Name or a process for modifying a data portion of the second CCN Name.

5. 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 transform a CCN Name in a CCN request before forwarding 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 a first CCN request including a 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, to generate a modified first CCN Name by removing the route transformer identifier from the first CCN Name, to generate a second CCN Name from the modified first CCN Name using the first process, to generate a second CCN request including the second CCN Name; and

to transmit the second CCN request toward a destination in the CCN network.

6. The network device of claim 5, wherein the route transforming module is further configured to generate a pending interest table (PIT) entry for the first CCN Name from the first CCN Request.

7. The network device of claim 6, wherein the route transforming module is further configured to generate a PIT entry for the second CCN request that associates the first CCN Name, a transform configuration, and the second CCN Name.

8. The network device of claim 7, wherein the transform configuration identifies a second process for generating the first CCN Name from the second CCN Name or a third process for modifying a data portion of the second CCN Name.

9. 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 transform a CCN Name in a CCN request before forwarding 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 a first CCN request including a first CCN Name, the first CCN Name including a route transformer identifier, the route transformer to identify a first process for modifying the first CCN Name, to generate a modified first CCN Name by removing the route transformer identifier from the first CCN Name, to generate a second CCN Name from the modified first CCN Name using the first process, to generate a second CCN request including the second CCN Name, and to transmit the second CCN request toward a destination in the CCN network.

10. The computing device of claim 9, wherein the route transforming module is further configured to generate a pending interest table (PIT) entry for the first CCN Name from the first CCN Request.

11. The computing device of claim 10, wherein the route transforming module is further configured to generate a PIT entry for the second CCN request that associates the first CCN Name, a transform configuration, and the second CCN Name.

12. The computing device of claim 11, wherein the transform configuration identifies a second process for generating the first CCN Name from the second CCN Name or a third process for modifying a data portion of the second CCN Name.

13. 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 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 transform a CCN Name in a CCN request before forwarding in the CCN network, the control plane device comprising:
