Abstract

Systems and methods for network communications bandwidth management and in particular to unified bandwidth manager that interfaces with and hierarchically manages a plurality of service-specific bandwidth reservation and session management systems. By utilizing a novel bandwidth management system, a better purpose specific bandwidth reservation system may thereby be achieved.

Claims

1. A system for bandwidth management in a communications network, the communication network having a plurality of network conditions and including connections with a plurality of service-specific bandwidth managers, the system comprising:

a high-level bandwidth manager including a control system, and an interface for providing at least policy information to the control system;

a control interface to each of the service-specific bandwidth managers, each control interface providing an ability for the high-level bandwidth manager to control at least one aspect of the associated service-specific bandwidth managers, each service-specific bandwidth managers affecting at least one associated network condition;

at least one reporting element associated with each of the service-specific bandwidth managers, each reporting element providing associated ongoing information to the high-level bandwidth manager, associated ongoing information responsive to at least one network condition affected by the associated service-specific bandwidth manager, and

at least one network communications processing resource,

wherein the control system is provided with a plurality of feedback inputs that are responsive to associated ongoing information from each of the associated reporting elements and availability of the network communications processing resoure;

wherein the control system uses said plurality of feedback inputs, together with the policy information to produce at least one element of outgoing control information;

wherein the at least one element of outgoing control information is conveyed to at least one of the service-specific bandwidth managers using the associated control interface.

2. The system of claim 1, wherein the control system utilizes a multi-service stochastic process blocking model.

3. The system of claim 1, wherein the reporting element comprises an information interface to one service-specific bandwidth manager.

4. The system of claim 3, wherein the information interface provides access to a file.

5. The system of claim 3, wherein the information interface provides access to an API.

6. The system of claim 3, wherein the information interface provides access a data stream.

7. The system of claim 1, wherein the reporting element comprises a network monitor separate from the service-specific bandwidth managers.

8. The system of claim 1, wherein the control interface access to a file.

9. The system of claim 1, wherein the control interface access to an API.

10. The system of claim 1, wherein the control interface provides access to a data stream.

11. The system of claim 1, wherein at least one of the service-specific bandwidth managers controls the admissions of Voice over IP calls.

12. The system of claim 1, wherein at least one of the service-specific bandwidth managers controls the admissions of video conferencing calls.

13. The system of claim 1, wherein at least one of the service-specific bandwidth managers controls the admissions of at least one of audio streaming sessions and video streaming sessions.

14. The system of claim 1, wherein at least one of the service-specific bandwidth managers controls the bandwidth allowed in admitted calls.

15. The system of claim 1, wherein at least one of the service-specific bandwidth managers controls the admissions of server access sessions.
