Claim:
1. A method for managing fragmentation of packets for content object retrieval at a content centric networking (CCN) gateway in a CCN network, the method comprising the steps of: 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; 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; forwarding the first CCN interest packet with updated fragmentation stream identifier and path minimum MTU toward a content provider; receiving a set of packets, including fragments of the first content object from the content provider; reassembling and verifying the first content object from the set of packets; refragmenting the first content object to minimum MTU of the access network and storing the refragmented first content object in a content store; and returning the first content object to the user equipment in the access network.
