Network communication bandwidth management
View Patent ↗A Unified Bandwidth Manager that functions as a high-level bandwidth manager to interface with and hierarchically manage a plurality of service-specific bandwidth reservation and session management systems is described. The Unified Bandwidth Manager includes at least a control system, and an interface for providing at least one of policy information or goal information to the control system. The control system is provided with a plurality of feedback inputs that are responsive to associated ongoing observation information from each of an associated observation reporting element. The control system uses the plurality of feedback inputs, together with the at least one policy information or goal information, to produce at least one element of outgoing control information.
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 at least a control system, and an interface for providing at least one of policy information and goal 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 observation reporting element associated with each of the service-specific bandwidth managers, each observation reporting element providing associated ongoing observation information to the high-level bandwidth manager, associated ongoing observation information responsive to at least one network condition affected by the associated service-specific bandwidth manager;
wherein the control system is provided with a plurality of feedback inputs that are responsive to associated ongoing observation information from each of the associated observation reporting elements;
wherein the control system uses said plurality of feedback inputs, together with the at least one policy information and goal 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 an observation reporting element comprises an observation information interface to one service-specific bandwidth manager.
3. The system of claim 2 , wherein the observation information interface includes a file.
4. The system of claim 2 , wherein the observation information interface includes an API.
5. The system of claim 2 , wherein the observation information interface includes a data stream.
6. The system of claim 1 , wherein an observation reporting element comprises a network monitor separate from the service-specific bandwidth managers.
7. The system of claim 1 , wherein the control interface includes a file.
8. The system of claim 1 , wherein the control interface includes an API.
9. The system of claim 1 , wherein the control interface includes a data stream.
10. The system of claim 1 , wherein the control system utilizes a multi-service stochastic process blocking calculator.
11. The system of claim 1 , wherein the control system is responsive to both policy information and goal information.
12. The system of claim 11 , wherein the control system comprises a hierarchical structure for implementing the responsiveness to both policy information and goal information.
13. The system of claim 1 , wherein at least one of the service-specific bandwidth managers controls the admissions of Voice over IP calls.
14. The system of claim 1 , wherein at least one of the service-specific bandwidth managers controls the admissions of video conferencing calls.
15. 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.
16. The system of claim 1 , wherein at least one of the service-specific bandwidth managers controls the admissions of server access sessions.
17. The system of claim 1 , wherein at least one of the service-specific bandwidth managers controls the admissions of database transactions.
18. The system of claim 1 , wherein at least one of the service-specific bandwidth managers controls the bandwidth allowed in admitted calls.
19. The system of claim 1 , wherein at least one of the service-specific bandwidth managers controls the bandwidth allowed in admitted streaming sessions.
20. The system of claim 1 , wherein the high-level bandwidth manager manages at least one network condition according to the at least one policy information and goal information.
