Data universal forwarding plane for information exchange

A computer-implemented method for routing in an information centric network (ICN), comprising:

• forwarding, from a node, an interest packet for first content, the interest packet including a first content name that describes the first content and an identifier of second content at a client device associated with the interest packet;
• storing, in at least one routing table, an association between the identifier of second content from the interest packet and a first interface corresponding to the interest packet;
• receiving, at the node, a data packet including data for the first content and the identifier of second content;
• and
• forwarding the data packet to the first interface based on the association of the identifier of second content with the first interface in the at least one routing table, wherein the at least one routing table includes a first routing table and a second routing table and storing the identifier comprises storing the identifier in the second routing table;
• determining, in response to the interest packet, whether the first routing table contains the first content name and one or more interfaces corresponding to the first content name;
• and
• forwarding the interest packet to the one or more interfaces identified in the first routing table when the first routing table contains the first content name;
• mapping the first content name to a first identifier of first content using a predetermined coding when the first routing table does not contain the first content name;
• determining whether the second routing table contains the first identifier and one or more or more interfaces associated with the first identifier;
• and
• forwarding the interest packet to one or more interfaces identified in the second routing table when the second routing table contains the first identifier.

A non-transitory computer-readable medium storing computer instructions for content routing, that when executed by one or more processors, cause the one or more processors to perform the steps of:

• route a first interest packet using a first routing table, the first interest packet comprising a first content name that describes first content requested by the first interest packet, the first interest packet comprising an identifier of second content at a first client device associated with the interest packet;
• store in a second routing table an association between the identifier of second content and a first interface corresponding to the first interest packet;
• receive a second interest packet comprising a second content name that describes the second content;
• route the second interest packet to the first interface based on the second routing table;
• and
• update the first routing table with an entry associating the second content name with the first interface when data for the second content is received in response to routing the second interest packet;
• receive a first data packet including data for the first content and the identifier of second content;
• determine from the second routing table the first interface based on the identifier of second content;
• route the first data packet to the first interface based on the second routing table;
• determine in response to the second interest packet whether the first routing table contains the second content name;
• hash the second content name to a second identifier of the second content using a predetermined coding in response to the first routing table not containing the second content name;
• and
• determine from the second routing table the first interface based on the second identifier.
