CONTENT CENTRIC NETWORK SYSTEM FOR DIFFERENTIATED SERVICES, EDGE ROUTER CONNECTED WITH CLIENT TERMINAL IN CONTENT CENTRIC NETWORK AND DIFFERENTIATED SERVICES PROVIDING METHOD IN CONTENT CENTRIC NETWORK

摘要

A content centric network system of the present invention includes: a client terminal (10) for generating an interest packet; an edge router (20) which is directly connected to the client terminal in a content concentric network for determining traffic classification for the interest packet with respect to the information included in the interest packet received from the client terminal and adding the determined traffic classification information to the interest packet; and a differential service router for storing the traffic classification information to a pending interest table (PIT) when receiving the interest packet to which the traffic classification information is added, and differentially transmitting data required by the interest packet depending on the traffic classification information.
