Abstract

In accordance with an embodiment, a network device has an input port for receiving input packets, and an output port for sending output packets, where the input packets and output packets have context layer information. The network device also includes a processor configured to process the input packets and output packets using a network protocol having a context layer.

Claims

1. A system for Context Label Switching comprising

a context label layer for managing context label for each content chunk, the context label comprising at least one of user ID information, interested content information, location information, time stamp information, and security information, wherein the context label layer comprises

a routing plane configured to determine a routing path for content chunk in accordance with the context label;

a service plane configured to process the content chunk; and

a cache plane configured to store and manage the content chunk in association with the context label.

2. The system of claim 1, wherein managing the context label comprises creating and inserting context label at a sender, modifying the context label at an intermediate relay node, and removing the context label at a receiver.

3. The system of claim 1, wherein the context label layer further comprises a forwarding plane configured to guide content chunk delivery associating the routing plane and manage content flow.

4. The system of claim 3, wherein the forwarding plane managing content flow comprises managing content flow for load balancing and traffic engineering and prioritizing traffic scheduling.

5. The system of claim 3, wherein the forwarding plane determines an egress interface for the content flow in accordance with a routing table from the routing plane and an action list defined by the service plane.

6. The system of claim 5, wherein the routing table includes mapping between a profile defined by the context label and I/O interface of the system.

7. The system of claim 1, wherein processing the content chunk comprises content distillation, dissemination, mash up, content aggregation and content chunk customization.

8. The system of claim 1, wherein the storing and managing the content chunk comprises storing the content chunk, updating the content chunk, retrieving the content chunk and synchronizing the content chunk with other CLS system, and removing duplicated content chunk.

9. The system of claim 1, wherein the routing plane is further configured to guide content search, to determine next hop, and to manage mobility anchoring and location service.

10. The system of claim 1, further comprising a management plane configured to provide an interface for operation, administration, maintenance and provisioning.

11. The system of claim 1, wherein the user ID comprises consumer ID, supplier ID and device ID.

12. The system of claim 1, wherein the time stamp information comprises time stamp when the content chunk is requested, time stamp when the content chunk is to be provided and how long the content chunk can exist in the system.

13. A method for Context Label Switching comprising

determining, by a routing plane of a context label layer, a routing path for a content chunk in accordance with a context label, context label being managed by the context label layer and comprising at least one of user ID information, interested content information, location information, time stamp information, and security information, wherein the context label layer performs

processing, by a service plane of the context label layer, the content chunk, and

storing and managing, by a cache plane of the context label layer, the content chunk in association with the context label.

14. The method of claim 13, wherein management of context label by the context label layer comprises creating and inserting the context label at a sender, modifying the context label at an intermediate relay node, and removing the context label at a receiver.

15. The method of claim 13, further comprising guiding, by a forwarding plane of the context label layer, the content chunk delivery associating the routing plane and managing content flow.

16. The method of claim 15, wherein managing content flow comprises managing content flow for load balancing and traffic engineering and prioritizing traffic scheduling.

17. The method of claim 15, further comprising determining, by the forwarding plane of the context label layer, an egress interface for content flow in accordance with a routing table from the routing plane and an action list defined by the service plane.

18. The method of claim 17, wherein the routing table includes mapping between a profile defined by the context label and an I/O interface of a system.

19. The method of claim 13, wherein processing the content chunk comprises content distillation, dissemination, mash up, content aggregation and content chunk customization.

20. The method of claim 13, wherein the storing and managing the content chunk comprises storing the content chunk, updating the content chunk, retrieving the content chunk and synchronizing the content chunk with other CLS system, and removing duplicated content chunk.

21. The method of claim 13, further comprising guiding, by the routing plane, content search, determining next hop, and managing mobility anchoring and location service.

22. The method of claim 13, wherein the user ID comprises consumer ID, supplier ID and device ID.

23. The method of claim 13, wherein the time stamp information comprises time stamp when the content chunk is requested, time stamp when the content chunk is to be provided and how long the content chunk can exist in a system.
