1. A computer-executable method for caching content data to a storage device attached to a switch in a content-centric network (CCN), the method comprising: receiving a first interest in a content packet; receiving, by the switch, the content packet; forwarding the content packet to an incoming port of the first interest in the content packet; caching a copy of the content packet in the attached storage device, wherein the attached storage device is coupled to the switch via a communication link, and wherein the copy of the content packet is stored in a set of storage blocks located in the attached storage device; assembling a query frame for retrieving content from at least one storage block, wherein the query frame is an Ethernet frame comprising: an Ethernet header having a MAC address of the attached storage device; and a logical block address (LBA) of a storage block in the set of storage blocks; storing the query frame in a cache table in the switch; and responsive to receiving an interest for content of the content packet, retrieving the query frame from the cache and transmitting the query frame to the attached storage device to retrieve the content packet based on the LBA, without assembling communication frames to retrieve the content packet.
