Method and apparatus for scalable content routing and mobility in named data networks

A method performed by a service router in a named data network (NDN) to route messages, comprising:

• receiving an interest message from a consumer node, wherein the interest message is used to express interest for content, and a header of the interest message includes a name of the content;
• Obtaining a forwarding label according to the name of the content, wherein the forwarding label indicates an address associated with a location of the content;
• and
• Sending an updated interest message to a next hop node in the NDN network, wherein a header of the updated interest message includes a first field containing the name of the content and a second field containing the forwarding label, and wherein the first field and the second field are two separate fields.

A service router for routing a message in a named data network (NDN), comprising:

• a processor;
• and
• a memory coupled to the processor and storing programming for execution by the processor;
• the processor configured to execute the programming to perform operations of:
• receiving an interest message from a consumer node, wherein the interest message is used to express interest for content, and a header of the interest message includes a name of the content;
• obtaining a forwarding label according to the name of the content, wherein the forwarding label indicates an address associated with a location of the content;
• and
• sending an updated interest message to a next hop node, wherein a header of the updated interest message includes a first field containing the name of the content and a second field containing the forwarding label, and wherein the first field and the second field are two separate fields.
