Abstract:
1. A method comprising: measuring, by an access point, the performance of a shared wireless channel by making direct measurements of: (a) a number of packets of both critical traffic and non-critical traffic transmitted during a time period, (b) transmission metrics associated with the transmission of those packets during the time period, and (c) a number of packets of critical traffic that experienced a transmission delay exceeding a predetermined amount of time during the time period, these direct measurements being made in order to estimate a residual bandwidth for a subsequent time period, wherein said residual bandwidth is in terms of a number of critical transmissions possible for the subsequent time period; and adjusting, by the access point, control parameters for transmission of critical traffic and non-critical traffic for the subsequent time period based on each of the direct measurements (a)-(c) so as to maintain a quality of service for critical traffic generated by critical applications and to optimize utilization of any residual bandwidth.
