    摘要： When receiving a streaming service from a service provision server, a user terminal wants QoS assurance and issues a QoS request to a QoS control server together with a communicate request to a network. In this case, by including information about a plurality of access networks that the user terminal can access in a QoS request message, a QoS control server can optimally allocate resources in the current environment of the user terminal and assure. QoS. In this case, the format of this QoS request can accompany a communicate request from the user terminal or be independent of the communicate request.

    摘要： A network fault diagnostic device is configured in the following manner. A causal relation table stores causal relations between faults and events, and a monitor event selector refers to the causal relation table to extract a minimum event required for identifying a fault, and sets the event as a monitor event. The acquisition-event selector selects events from the causal relation table based on latest fault candidates, and sets priorities of the events selected, in the order of efficiently identifying faults. The event acquiring unit requests events in the order of the priorities set, and the event receiving unit receives each event in response to the respective requests. The fault determining unit narrows down the candidates of the fault based on the events received one by one.
