Abstract: A multimedia conference reservation controller and reservation acceptance system includes a database of all presently reserved resources on each MMS controlled by the reservation controller which includes an identification of each resource together with the starting time and ending time of the reservation. The acceptance system is designed to accept a reservation query which includes a list of required resources and a list of flexible resources, where flexible resource are considered desirable resources, but not absolutely necessary resources. In response to a reservation query involving a single MMS, the acceptance system accesses the database and builds a list of resources together with the times during which those resources are already reserved. This list is used to create a Resource Availability Matrix which is then analyzed and a list of time periods is generated during which the requested resources are available.
