<object><abstract>   This draft introduces the new challenges for the network brought by
   massive access services under the background of the convergence of
   the cloud and the network which acquires the network to identify and
   convey the information of fine-grain user and application
   requirements, aiming to fulfill differentiated service provisioning
   and improve the comprehensive utilization of network resources.  The
   draft raises the scope of current solution gap analysis and further
   proposes the definition of DB-ORS in which network capabilities are
   abstracted as atomic services and can be orchestrated by
   applications.  Scenarios of cloud access and DCI are outlined to
   clarify the concepts and principles of DB-ORS in overcoming
   challenges.
