CONTENT DISTRIBUTION SYSTEM, NETWORK APPARATUS, AND OPERATION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a content distribution system configured to efficiently implement content distribution at the terminal of a network that distributes a content to a user terminal, especially.SOLUTION: A communication section 51 communicates with a plurality of user terminal devices 14 through a plurality of communication channels. A request receiving section 52 receives content acquisition requests transmitted from the user terminal devices 14. A content distribution section 55 transmits content data to the user terminal devices 14. A redundancy detection section 56 detects that the same content acquisition request has been received from a second user terminal device through a second communication channel after receiving the content acquisition request from a first user terminal device through a first communication channel. A channel shifting section 57 shifts the communication channel used by the second user terminal device 14, to the first communication channel.SELECTED DRAWING: Figure 3
