  • Distribution management method, a distribution management system and a distribution management server
    Patent number: 7979515
    Abstract: A distribution management system is provided which can have a high software distribution efficiency by using client terminals substituting for software distribution relay and can reliably collect distribution results without depending upon the statuses of client terminals. A distribution management server groups a plurality of representative clients in charge of software distribution relay, and changes assignment of software distribution target client terminals by monitoring the distribution execution status of each representative client terminal. Further, the client terminal can reliably notify the distribution result to the distribution management server in accordance with a list of grouped representative client terminals. Furthermore, for the client terminal not notifying the distribution result even if the notice term expires, a distribution result notice representative client terminal is set further so that the distribution result can be reliably notified to the distribution management server.
