Abstract
An architecture for multi-channel CSMA systems using an 802.11 protocol includes a MAC for each a station, wherein each MAC includes plural transmit queues, a queue selection mechanism, and a holding queue; a physical layer having multiple channels therein; and a receiver for each station, each receiver having a re-ordering buffer for ordering packets in a proper sequence prior to the packets leaving the receiver. A method of providing high throughput in an 802.11 CSMA system includes selecting an optimum transmission route for a packet to be transmitted, including: selecting an optimum transmit queue; selecting an optimum channel in the physical layer; and transmitting the packet over the optimum transmission route.
