1. A method of transmitting a content reply packet from a content owner in content-centric networking (CCN), the method comprising: determining, using a determining processor, a caching capability value threshold (CCVth) for determining a candidate node for caching a content based on a policy of the content owner; and transmitting, using a transmitting processor, a content reply packet including the content and the CCVth in response to a content request packet from a content requester, wherein all nodes cache the content in response to the CCVth having a first value, no nodes cache the content in response to the CCVth having a second value, and a node having a caching capability value (CCV) greater than a third value caches the content in response to the CCVth having the third value, wherein the content reply packet further comprises any one or any combination of an original network distance value (oNDV) between the candidate node and the content owner included in the content request packet, a decreasing network distance value (dNDV) that decreases with downstream forwarding of the content reply packet, a maximum CCV included in the content request packet, a weight value, and a lifetime of the content. |
