Abstract
A system and method for implementing fairness in the powering of computing devices in a power over Ethernet (PoE) application. Power supplies in a power sourcing equipment are often oversubscribed. This oversubscription can lead to starvation of certain computing devices that have power requests that are not granted relative to competing requests. A fairness consideration can be implemented to ensure that starvation conditions are avoided.
Claims13
A power over Ethernet method, comprising:
- receiving at least two power requests from a computing device, each of said power requests representing alternative requests for power for said computing device;
- approving one of said at least two power requests;
- and
- allocating power to said computing device based on said approved power request.
1 more element
A power over Ethernet method, comprising:
- receiving a power request from a computing device;
- and
- allocating power to said computing device based on approval of said power request, wherein said allocation of power to said computing device is limited in duration to a period of time that is identified prior to said allocation.
