Patent ID: 8542588

Claim:
A method comprising: determining that a wireless channel will carry a first class of traffic and a second class of traffic, wherein presentation of content conveyed by the first class of traffic has a lesser degree of presentation time sensitivity than presentation of content conveyed by the second class of traffic; and instantiating different wireless link rate determination operations for the first class of traffic and the second class of traffic that determine wireless link rates for wireless transmission of data units of the first and second classes of traffic, wherein the different wireless link rate determination operations correspond to the different degrees of presentation time sensitivity, wherein the wireless link rate determination operations for the first class of traffic aggressively probe for a maximum wireless link rate and the wireless link rate determination operations for the second class of traffic conservatively probe for a smooth wireless link rate that accommodates a greater degree of presentation time sensitivity of data units of the second class of traffic relative to the presentation time sensitivity of the data units of the first class of traffic, wherein the wireless link rate determination operations for the second class of traffic operate within an upper threshold and a lower threshold.
