NETWORK TRAFFIC PRIORITIZATION

摘要

Management of throughput, link rate, airtime, access, collision probability and other factors influencing performance of a wireless access point configured to wirelessly support two or more networks over the same radio channel and/or antenna is contemplated. The management may be suitable for use with access points operating according to a Distributed Coordination Function (DCF) based on Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) whereby each device desiring airtime executes a random binary backoff procedure or other suitable contention based process before attempting to access the channel.

1. A non-transitory computer-readable medium having non-transitory instructions operable with a wireless access point to manage airtime when the wireless access point wirelessly supports a public network and a private network over a single radio channel and access to airtime on the channel is controlled according to a Distributed Coordination Function (DCF) based on Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) whereby each device desiring airtime executes a random binary backoff procedure before attempting to access the channel, the random binary backoff procedure characterized by each device attempting to access the channel during a backoff slot selected from a plurality of backoff slots defined in one of a private contention window and a public contention window, wherein devices connected to the private network select from backoff slots defined in the private contention window and devices connected to the public network select from backoff slots defined in the public contention window, the non-transitory instructions being sufficient for:
defining the private contention window according to a private contention window minimum (CWminpriv) having a first plurality of backoff slots; defining the public contention window according to a public contention window minimum (CWminpub) having a second plurality of backoff slots; and arbitrating airtime according to a dynamic mode when at least one device is connected to each of the private network and the private network, the dynamic mode including: i) determining at least one metric representative of network conditions known to the wireless access point while the at least one device is connected to each of the private network and the private network; ii) selecting the CWminpriv to be a first value; and iii) selecting the CWminpub to be a second value determined by scaling the first value as a function of one or more of the at least one metric.
