METHOD OF TRANSMITTING DATA PACKET FROM CONTENT PROVIDER IN CONTENT-CENTRIC NETWORK AND CONTENT PROVIDER

摘要

A method of transmitting a data packet from a content provider in a content-centric network CCN includes verifying whether a content request packet requesting a content identical to a content of a content request packet being received from a content requester is present in a pending interest table (PIT), increasing a value of a counter corresponding to the content request packet, comparing the value of the counter to a predetermined threshold value, and transmitting a data packet using a predefined broadcast media access control (MAC) address in response to the content request packet being received and the value of the counter being greater than or equal to the threshold value.
