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:

receive a reservation from a customer, wherein the reservation comprises a reservation time;

reserve a network resource specified in the reservation;

establish a reserved connection through a network at the reservation time, the reserved connection based on the reservation;

subsequent to the establishment of the reserved connection, detect a data stream transmitted from the customer via a plurality of parallel connections coupling the customer to the network;

allow the data stream to be transported over the network using the reserved connection;

receive a data termination message as part of the data stream; and

terminate the reserved connection responsive to receiving the data termination message, wherein the customer is not part of the network, and wherein the reservation dictates the bandwidth allocated to each of the parallel connections.

2. The telecommunications network component of claim 1, wherein the reserved connection is established through the network,

wherein the establishment of a reserved connection reduces the network resources available in the network,

wherein the reservation time comprises a start time, and a duration, and

wherein the network resource is bandwidth.

3. The telecommunications network of claim 1, wherein the reservation is received by a reservation scheduling system (RSS),

wherein the reserved connection is established by a control plane that has knowledge of the network, and

wherein the control plane is not part of either the RSS or a network management system.

4. The telecommunications network of claim 3, wherein the control plane modifies the reserved connection based on conditions within the network.

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

submitting a reservation request specifying a bandwidth requirement and a start time to a reservation scheduling system (RSS), wherein the RSS interacts with a network management system and a control plane to make the reservation within the network, and wherein the reservation request is not submitted via a data plane or the control plane;

receiving a confirmation that the reservation has been accepted from the RSS; and

subsequently transmitting a data stream to the data plane at the start time,

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

wherein the data stream comprises a data termination message that indicates the end of the data stream.

6. The method of claim 5, wherein the reservation request further comprises a duration or a stop time, and a reservation frequency that indicates when the reservation will reoccur, and 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.

7. The method of claim 6, 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.

8. The method of claim 5, wherein the data is transmitted to the data plane via a plurality of parallel connections, and wherein the reservation dictates the bandwidth allocated to each of the parallel connections.

9. The method of claim 5, wherein the control plane has knowledge of the network,

wherein the control plane is not part of either the RSS or the network management system,

wherein the control plane establishes a path through the network based on the reservation, and

wherein the data stream is transported over the network via the path.

10. The method of claim 9, wherein the control plane modifies the path based on conditions within the network.

11. The method of claim 9, wherein the control plane terminates the path upon the data plane receiving the data termination message.

12. A system comprising:

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

a reservation scheduling system (RSS) in communication with the control plane, a network management system, and a customer that originates a reservation; and

a plurality of connections through the network from the customer,

wherein the customer only interacts with the RSS to establish the reservation and the RSS interacts with the NMS and/or the control plane to establish the reservation;

wherein the reservation dictates the bandwidth allocated to each connection,

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

wherein the customer transmits a data termination message to end the reservation.

13. The system of claim 12, wherein the customer initiates a reservation request, and wherein the data plane transmits the data without receiving any reservation information from the customer.

14. The system of claim 13, wherein the control plane does not receive the reservation request from the customer, and wherein the reservation scheduling system does not receive the data from the customer or the data plane.

15. The system of claim 12, wherein the network is an Automatically Switched Optical Network (ASON) or Generalized Multi-Protocol Labeling Switching (GMPLS) network, and wherein the network is an optical network.

16. The system of claim 12, wherein there is not a user network interface between the control plane and the customer.

17. The system of claim 12, wherein the control plane has knowledge of the network,

wherein the control plane is not part of either the reservation scheduling system or a network management system, and

wherein the control plane establishes a path through the network for the data received from the customer.

18. The system of claim 17, wherein the control plane modifies the path based on conditions within the network.

19. The system of claim 17, wherein the control plane terminates the path upon receiving the data termination message.

20. The system of claim 12, wherein the customer transmits the data termination message on the data plane.
