Patent number: 7711817Abstract: In each of the information processing apparatuses connected to each other via a network, there is arranged a quality of service (QOS) table to which functions and performance thereof are registered. When an information processing apparatus is additionally linked with the network, a QOS table thereof is automatically registered to a local directory of the network such that an agent converts the contents of the QOS table into service information to be supplied via a user interface to the user. Thanks to the operation, information of functions and performance of each information processing apparatus connected to the network is converted into service information for the user. Consequently, the user can much more directly receive necessary services.Type: GrantFiled: October 1, 2008Date of Patent: May 4, 2010Assignee: Hitachi, Ltd.Inventors: Ryuichi Hattori, Toshihiko Ogura, Takashi Oeda, Koichi Okazawa, Hideki Osaka, Tsunehiro Tobita, Tsutomu Hara
