DATA RELAY APPARATUS AND METHOD, SERVER APPARATUS, AND DATA SENDING METHOD

摘要

A relay node includes interfaces, a request statistical table that stores therein information concerning a request in an entry generated for each chunk, a request statistics processor that records a reception time and sending source information concerning a request in the request statistical table, a target request determining unit that determines whether or not a currently received request is a target request, a delay amount determining unit that determines a delay amount for a received request, which is a target request, and a delay processing unit that delays forwarding a received request or content data for a delay amount.

主权项

1. A data relay apparatus in information centric networking (ICN) comprising:
communication circuitry that receives a request corresponding to a chunk divided from content data, the chunk being a predetermined unit of the content data, forwards the received request, receives the content data in response to the received request, and forwards the received content data; a request statistical table that stores therein information concerning the received request in an entry generated for each chunk corresponding to each request; and control circuitry, which in operation:
records a reception time and sending source information concerning the received request as the information in the entry generated in the request statistical table;determines that the received request is a target request, by referring to the request statistical table, if the request statistical table includes an entry for a previous chunk positioned previous to a chunk corresponding to the received request in an arrangement order of chunks forming the content data and if requests corresponding to the previous chunk have been received from a plurality of different sending sources for a predetermined time;determines a delay amount for the received request if the received request is determined to be the target request; anddelays forwarding the received request for the delay amount.
