1. A method for establishing a data conference between a node and an end point of a communication network, comprising the steps of:
- (a) requesting from the end point a reserved bandwidth for a data conference having a specified start time;
(b) receiving confirmation of the reserved bandwidth from the end point, wherein, during a predetermined time window around the start time, the end point terminates or rejects other uses of the reserved bandwidth to ensure that the reserved bandwidth is available for the data conference; and
(c) establishing the data conference with the end point within the predetermined time window.

Abstract
A system, method, apparatus, and storage medium for establishing a data conference with an end point of a communications network. According to one embodiment, a node requests from the end point a reserved bandwidth for a data conference having a specified start time. The originating end point receives confirmation of the reserved bandwidth from the end point. The originating end point establishes the data conference with the end point within a predetermined time window around the start time.

11. A system for establishing a data conference over a communications network, comprising:
-
(a) an end point of the network; and (b) a node of the network for requesting from the end point a reserved bandwidth for a data conference having a specified start time, for receiving confirmation of the reserved bandwidth from the end point, and for establishing the data conference with the end point within a predetermined time window around the start time, wherein, during the predetermined time window, the end point terminates or rejects other uses of the reserved bandwidth to ensure that the reserved bandwidth is available for the data conference. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A node of a communicates network, the node comprising:
-
a communications port through which communicates with other end points of the communications network is effected; a storage device having stored therein a plurality of instructions for establishing a data conference between the node and an end point of the communications network; and a processor coupled to the communications port and to the storage device for executing the plurality of instructions, wherein the processor, via the communications port; (a) requests a reserved bandwidth for a data conference having a specified start time from the end point; (b) receives a confirmation of the reserved bandwidth from the end point, wherein, during a predetermined time window around the start time, the end point terminates or rejects other uses of the reserved bandwidth to ensure that the reserved bandwidth is available for the data conference; and (c) establishes the data conference with the end point within the predetermined time window.

21. A storage medium having stored thereon a plurality of instructions, wherein the plurality of instructions, when executed by a processor of a node of a communications network, cause the processor to perform the steps of:
-
(a) requesting from an end point of the communications network a reserved bandwidth for a data conference between the node and the end point having a specified start time; (b) receiving confirmation of the reserved bandwidth from the end point, wherein, during a predetermined time window around the start time, the end point terminates or rejects other uses of the reserved bandwidth to ensure that the reserved bandwidth is available for the data conference; and (c) establishing the data conference with the end point within the predetermined time window.

22. In a end point of a communication network, a method for establishing a data conference with a node of the communications network, the method comprising the steps of:
-
(a) receiving a request from the node for a reserved bandwidth for a data conference having a specified start time; (b) determining whether to accept the request; (c) transmitting confirmation of the reserved bandwidth to the node if the request is accepted in step (b); (d) freeing up the reserved bandwidth at or near the beginning of the time window by terminating or rejecting other uses of the reserved bandwidth to ensure that the reserved bandwidth is available for the data conference; and (e) rejecting calls received during the time window except for a call from the node.

23. An end point of a communications network the end point comprising:
-
a communications port through which communications with other end points and nodes of the communications network is effected; a storage device having stored therein a plurality of instructions for reserving bandwidth for a data conference with a node of the communications network; and a processor coupled to the communications port and to the storage device for executing the plurality of instructions, wherein the processor, via the communications port; (a) receives a request from the node for a reserved bandwidth for a data conference having a specified start time; (b) determines whether to accept the request; (c) transmits a confirmation of the reserved bandwidth to the node if the request is accepted; (d) frees up the reserved bandwidth at or near the beginning of the time window by terminating or rejecting other uses of the reserved bandwidth to ensure that the reserved bandwidth is available for the data conference; and (e) rejects calls received during the time window except for a call from the node.
