Abstract
Embodiments of the present invention are directed to controlling device access fairness in frame-based switches by automatically and continuously counting the number of actively communicating devices connected to each port and the type of devices connected to each port, and adjusting fairness accordingly. During a sampling window, the number of active devices and the type of devices connected to each port is determined. At the start of each fairness window, a weighted number of slots are assigned to each port based on the number of active devices connected to each port and the type of devices connected to that port. Within a single fairness window, each port is able to provide device accesses to the frame-based switch in accordance with the number of slots assigned to that port.
