The station receives a first message from the access point in the wireless network, the first message includes a first hashed service set identifier (SSID) generated by the access point by performing a first hash function on an SSID associated with the access point.

Abstract: Selectively ignoring congestion conditions may allow for more efficient transmission control protocol (TCP) communication in instance where reducing the transmission rate for a flow will not meaningfully mitigate congestion in the network or is otherwise undesirable. By way of example, congestion conditions may be ignored when a specific type of traffic flow is being communicated (e.g., short flows, high priority flows, etc.), when a traffic flow is being communicated at a low transmission rate, when a traffic flow is destined for certain type of network (e.g., a wireless network, etc.), or during any other situation in which reducing the transmission rate is undesirable. In some networks, a transmission rate is maintained until a certain number of duplicate ACKs are received (e.g., three duplicate ACKs, etc.) in order to ensure that congestion is indeed present before reducing quality of service (QoS).
