  • Patent number: 7212491
    Abstract: An integrated QoS control system is provided that transmits, in real time, the stream data between a bandwidth-guaranteed network and a bandwidth-not-guaranteed network. The QoS manager 102 records the remaining bandwidth of the bandwidth-guaranteed network 2 captured by the remaining bandwidth table capturer 103 and the remaining bandwidth of the bandwidth-not-guaranteed network 1 calculated with traffic information notified by the network status monitor 107 on the use bandwidth registration table 104 (for comprehensively managing the bandwidth of an integrated network). The Qos manager 102 converts a QoS parameter received via the QoS request receiver 106 into a traffic parameter and controllably adapts the value of the traffic parameter to a service quality required by the application 109.

  • Publication number: 20020004748
    Abstract: A program or an advertisement that was broadcast is received, for example, by a user terminal 41 for a user A, and a corresponding “information icon” is stored in the user terminal 41. Later, when the user A selects the “information icon” which he/she would like to know in details, a “detailed my page” customized for the user A is transmitted from an information management center 3. If the user A who viewed display contents of the “detailed my page” would like to invite a user B who is one of his/her friends, he/she transmits an electronic mail with the corresponding “information icon” attached, which was addressed to a user terminal 42. Later, When the user B perused contents of the received electronic mail, and selects the “information icon” in order to know the details thereof, the “detailed my page” adjusted individually for the user B is transmitted from the information management center 3.
