The method includes receiving a first CCN interest packet including a name for a first content object from a user equipment in an access network, storing a fragmentation stream identifier in a header of the first CCN interest packet, and setting a path minimum maximum transmission unit (MTU) in the first CCN interest packet to an MTU value required by a link between the CCN gateway and a node forwarding the first CCN interest packet to the CCN gateway. The method further includes forwarding the first CCN interest packet with updated fragmentation stream identifier and path minimum MTU toward a content provider, receiving a set of packets of including fragments of the first content object from the content provider, reassembling and verifying the first content object from the set of packets, and refragmenting the first content object to minimum MTU of the access network and storing the refragmented first content object in the content store. The first content object is then returned to the user equipment in the access network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"CCN fragmentation gateway","description":"A method is provided for managing fragmentation of packets for content object retrieval at a content centric networking (CCN) gateway in a CCN network.
