Abstract

A telecommunications network comprising components configured to implement a method comprising: receiving a reservation from a customer, reserving a network resource specified in the reservation, initiating the establishment of a reserved connection through a network, the reserved connection parameters based on the reservation, subsequent to the establishment of the reserved connection, detecting a data stream transmitted from the customer, and allowing the data stream to be transported over the network using the reserved connection. Also disclosed is a method for reserving bandwidth on a network, the method comprising: submitting a reservation request specifying a bandwidth requirement and a start time, receiving a confirmation that the reservation has been accepted, and transmitting a data stream to a network at the start time, wherein the data stream is transported over the network using no more than the bandwidth specified in the reservation request.

Claims

1. A telecommunications network comprising components configured to implement a method comprising:

receiving a reservation from a customer;

reserving a network resource specified in the reservation;

initiating the establishment of a reserved connection through a network, the reserved connection parameters based on the reservation;

subsequent to the establishment of the reserved connection, detecting a data stream transmitted from the customer; and

allowing the data stream to be transported over the network using the reserved connection.

2. The telecommunications network component of claim 1, wherein the reserved connection is established through the network, and wherein the establishment of a reserved connection reduces the network resources available in the network.

3. The telecommunications network component of claim 1 further comprising:

initiating the discontinuation of the data stream transmission over the reserved connection.

4. The telecommunications network component of claim 1, wherein the method further comprises:

initiating the termination of the reserved connection when the reservation expires.

5. The telecommunications network component of claim 1, wherein the method further comprises:

initiating the termination of the reserved connection when a data termination message is detected.

6. The telecommunications network component of claim 1, wherein the reservation comprises a start time, and a duration.

7. The telecommunications network component of claim 6, wherein the network resource is bandwidth.

8. A method for reserving bandwidth on a network, the method comprising:

submitting a reservation request specifying a bandwidth requirement and a start time;

receiving a confirmation that the reservation has been accepted; and

transmitting a data stream to a network at the start time;

wherein the data stream is transported over the network using no more than the bandwidth specified in the reservation request.

9. The method of claim 8, wherein the reservation request further comprises a duration or a stop time.

10. The method of claim 9, further comprising:

submitting a reservation extension, and continuing to transmit the data after the duration or stop time has occurred, the data stream continuing to be transported over the network using no more than the bandwidth specified in the reservation request.

11. The method of claim 8, wherein the data stream comprises a data termination message that indicates the end of the data stream.

12. The method of claim 8, wherein the reservation request further comprises:

a reservation frequency that indicates when the reservation will reoccur.

13. The method of claim 8, wherein the bandwidth specified in the reservation request changes based on one or more of the following:

the time of day, the day of the week, and the properties of the data.

14. A system comprising:

a network comprising a plurality of nodes having a control plane and data plane; and

a reservation scheduling system in communication with the control plane and a customer that originates a reservation;

wherein the data plane transmits data received from the customer over the network based on the reservation.

15. The system of claim 14 further comprising:

a plurality of connections between the network and the customer, wherein the reservation dictates the bandwidth allocated to each connection.

16. The system of claim 14, wherein the data plane transmits the data without receiving a connection request through a user network interface (UNI) signaling channel.

17. The system of claim 14, wherein there is no a signaling channel between the control plane and the customer.

18. The system of claim 14, wherein the network is an optical network.

19. The system of claim 14, wherein the network is an Automatically Switched Optical Network (ASON) or Generalized Multi-Protocol Labeling Switching (GMPLS) network.

20. The system of claim 14, wherein there is no a user network interface between the control plane and the customer.
