Abstract: Provided is a communication method of a node, including receiving a first interest requesting content from a previous node in a content centric network (CCN), generating a first acknowledgment (ACK) message indicating reception of the first interest in response to receiving the first interest, and sending the first ACK message to the previous node. Provided also is a node that includes structure that is suitable to perform such a communication method.

Abstract: A method of estimating a round-trip time (RTT) is provided. The method may include providing content requested by an interest packet with an identifier to identify a second node that sends the content to the first node, determining a processing time (PT) in which an interest packet is processed in the second node, based on an arrival time in which the content is received by the first node, evaluating an instantaneous RTT for the content received by the first node, based on an arrival time in which the content with the identifier is received at the first node, a sending time in which the interest packet is sent to the second node, or the determined PT, and estimating an RTT for the interest packet based on the evaluated instantaneous RTT.
