A system and method are provided which enable a data communications device to be programmed to automatically and dynamically modify allocation of resources upon the occurrence of specific events or times without have to break active sessions of data communications. Resource allocations can be made by bandwidth reservations provided to a data communications device via a network policy or via individual bandwidth reservation messages. The bandwidth allocation information can specify a session of data communication and future bandwidth modification information, such as a time or event, that will cause the data communications device to modify an amount of bandwidth reserved for the specified session of data communications. In operation, a data communications device receives bandwidth allocation information indicating future bandwidth allocation modification information associated with a session of data communication. The data communications device then can determine a future event upon the occurrence of which the data communications device will modify an amount of bandwidth allocated to the session of data communication. The future event can be determined based upon the future bandwidth allocation modification information and event information such as a time signal from a clock or another event signal. The data communications device can detect the occurrence of the future event in the data communications device and in response to detecting its occurrence, can modify the amount of bandwidth allocated to the session of data communications in the data communications device. Extensions to a bandwidth reservation protocol such as the RSVP protocol are defined which allow RSVP bandwidth reservation messages to specify the future bandwidth modification information. The systems and methods of the invention may be implemented in hardware, software or a combination thereof within a data communications device such as a router, switch, hub or other network device that handles the transfer of data.
