SYSTEM AND METHOD FOR HIGH QoS DIGITAL CONTENT-BASED SERVICES

摘要

A digital content mediator ("DCM") communicates with a network resource controller/manager (NRM) to allocate the appropriate network resources for a digital content transfer. A DCM client provides a signal to the DCM requesting the desired digital content transaction. The DCM checks a content information database to see if the content transfer is allowed. If the transfer is allowed, the DCM then extracts content transfer information from the content information database that describes network resource characteristics for transfer of that content. The DCM then formulates a request to the Network Resorce Manager containing the source and destination endpoint information in addition to the network resource characteristics of the content to be transferred. The Network Resource Manager (NRM) then makes the appropriate resource allocations. If the request succeeds, the DCM "approves" the request and signals to the client that the transfer process can continue. At the end of the transfer process, after the DCM has verified that the destination user has received the desired digital content, the DCM provides a "signal" to the NRM requesting that the reserved network resources be de-allocated.
