SonicWave 600 Series Deployment Guide
SonicPoint FairNet Features
The following features are included with SonicPoint FairNet:
-
Distributed Coordination Function
The Distributed Coordination Function (DCF) provides timing fairness for each client to access a medium with equal opportunity. However, it cannot guarantee the per-station data traffic fairness among all wireless clients. The SonicPoint FairNet feature is implemented on top of the existing 802.11 DCF to guarantee fair bandwidth among wireless clients regardless of the number and direction of flows.
-
Traffic Control
The traffic control feature decides when packets are queued or dropped (for example, when the queue has reached a length limit, or when the traffic exceeds a rate limit). It can also decide in which order packets are sent (for example, to give priority to certain owners) and it can also delay the sending of packets (such as limiting the rate of outbound traffic). After traffic control has released a packet to send, the device driver picks it up and submits it to the network.
Fairnet is unsupported on the SonicPoint Ni or Ne access points.
