Title: METHOD AND SYSTEM FOR COLLECTING HISTORICAL NETWORK INFORMATION IN A CONTENT CENTRIC NETWORK
Abstract:
One embodiment provides a system that facilitates collection of historical network information. During operation, the system monitors a plurality of packets which include outgoing interests and corresponding incoming content objects, wherein a name for an interest is a hierarchically structured variable length identifier that includes contiguous name components ordered from a most general level to a most specific level. The system collects historical information associated with the packets based on name prefixes of the packets, wherein a name prefix includes one or more contiguous name components. In response to receiving a query from a requesting entity for the historical information, the system transmits the historical information, thereby facilitating the requesting entity to use the historical information to increase network efficiency.
