What is the scope of the session protocol?
A DSM-CC session groups all the resources used in an instance of a service. This is accomplished by tagging the resources with the network wide unique session ID. Consequently, the logging of all the resources for later use in billing is made possible. The session ID tag also facilitates the disposal of the resources when the session is released so that they can be made available to other service instances. Occasionally the resources are disposed off when a service is suspended in an active session and reestablished when it is resume later. In some situations when a service is changed by a Client, the release of some critical resources may be delayed for a short time to allow for the resources to be used by the Client in the new service without incurring the penalties for a new connection establishment. This occurs in situations where a Client suspends a given service and moves to another service. A connection is reused if the resources QoS matches or is larger than the QoS required by
