Abstract
Methods and systems for a wireless ATM network with high quality of service scheduling are provided. In one embodiment, a wireless ATM network with per-VC scheduling, a virtual framer for periodical, request-less scheduling, and a virtual shaper for request-based scheduling are provided.
Claims10
A system for a shared-medium cell-based metropolitan area network including:
- a plurality of terminals;
- and
- a base station for transmitting and receiving from said terminals over the shared medium,
- wherein said base station includes a scheduler that regulates the upstream flow of cells by broadcasting grants with permissions to transmit,
- wherein bandwidth requests from said terminals include information identifying the requesting virtual circuit, and
- wherein said scheduler includes a virtual framer that provides request-less periodical grants for one or more virtual circuits.

- a base station for transmitting and receiving from said terminals over the shared medium,
- wherein said base station includes a scheduler that regulates the upstream flow of cells by broadcasting grants with permissions to transmit,
- wherein bandwidth requests from said terminals include information identifying the requesting virtual circuit,
- wherein said scheduler includes a virtual framer that provides periodical grants for one or more virtual circuits and a virtual shaper, wherein said virtual shaper generates next compliant times based on the last compliant time of a dual-leaky bucket implementation.
