33、width) available on end user network connections. Changes in QoS may be applied on either a temporary basis (i.e. for a defined period of time), or as the default QoS to be applied for a user each time they connect to the network. Applications will govern the quality of service available to the end
34、user by requesting that pre-defined QoS Feature profiles are applied on the end users connection. It is the responsibility of the Service Provider to define these QoS Features and share them beforehand with application providers, along with a clear indication as to which of these can be used as temp
35、orary QoS Features and which can be used to set the default QoS on an end user connection. The following scenarios provide example business use-cases to further illustrate the difference between default and temporary QoS Features and when they may be applied by the application. End User ISP App ADQ
36、WSEU wishes to upgrade to faster ISP Servi ce offering E.g. DSL 2048 kbps to 8192 kbpsUpgrade to “Broadband Gold” productapplyQoSFeature()defa ul tQ oS Featu re = T rueQoSFeature = DSL_8192EU QoS Profile will be applied on a permanent basis. I.e. each time EU terminal attaches to network .Figure 4.1
37、: Example Default QoS Feature Use-Case Figure 4.1 provides an example of where a default QoS Feature could be applied to an end user connection. The scenario given shows the end user of a DSL service requesting a permanent upgrade from their existing service offering (e.g. 2048 kbps) to a higher ban
38、dwidth service (e.g. 8192 kbps). The application subsequently makes a request to the ADQ web service to apply the pre-defined DSL_8192 QoS Feature to the end user connection on a permanent, or default, basis. Following successful completion of this use-case, each time the end users terminal equipmen
39、t attaches to their DSL service, the default QoS (in this case DSL_8192) will be applied. ETSI ETSI ES 202 504-17 V1.1.1 (2008-05) 9 End UserVideo Server AppADQ WSEU wishes to stream a video lasting 3 hours, but requires t em p or ar y bandwidth upgrade to support streami ng. E.g.

41、e. f or 3 hr s, or u nt il us er terminates connection).Figure 4.2: Example Temporary QoS Feature Use-Case Figure 4.2 provides an example of where a temporary QoS Feature could be applied to an end user connection. The scenario given shows an end user of a DSL service who wishes to stream a piece of
42、 video content. Their current service offering (e.g. 1024 kbps DSL) however will not support video streaming and hence they require a temporary bandwidth upgrade for the duration of the video stream. The streaming application then makes a request to the ADQ web service to apply the pre-defined Downl
43、oad_QoS QoS Feature to the end user connection, specifying the upstream and downstream bandwidth rate and the duration for which the temporary QoS Feature should be applied. Assuming that the network supports the requested bandwidth rate, the end users bandwidth will be increased to the rate request
44、ed by the application for the specified duration. Once the requested duration has expired, the end users service will resume to their original (in this example 1024 kbps bandwidth) QoS. Figure 4.3: ADQ Web Service ETSI ETSI ES 202 504-17 V1.1.1 (2008-05) 10The ADQ service is enabled as a Web Service
45、 interface, as depicted in figure 4.3, and will accept four logical kinds of requests from the Applications viz.: Requests to change the default quality of service available on the end users connection, Requests to change the quality of service available on the end users connection on a temporary ba
46、sis, Requests to manage event registrations and Self-care requests. Applications can register with the service for notifications about network events that affect the quality of service temporarily configured on the end users connection. Whenever such events occur, the Service generates notifications
47、 to inform Applications about the impact that these events had on the temporary QoS features set up on the end users connection. Self-care requests enable Applications to view transaction history and current quality of service status. 5 Namespaces The ApplicationQoS interface uses the namespace: htt
