A network performance specifying device that specifies guaranteed, controlled or unspecified service classes for multipoint, multimedia communication services. The network performance specifying device permits an end-user to differentiated multimedia communication services (e.g., high quality to low quality and high cost to low cost) as may be specified via a standard set of parameters to instruct underlying transport layers to provide corresponding services that result in guaranteed quality of service for the end-user. This standard set of parameters allows end-users to select service classes for each type of media which guarantee a predetermined level of quality. <IMAGE> |
