Figure 3 Traffic Flow diagram
Each wireless device sends IP packets in the 802.11 standard to the Wireless AP. The Wireless
AP uses a UDP (User Datagram Protocol) based tunnelling protocol to encapsulate the packets
and forward them to the HiPath Wireless Controller. In a typical configuration, APs can be
configured to locally bridge traffic (to a configured VLAN) directly at their network point of
attachment. The HiPath Wireless Controller decapsulates the packets and routes these to
destinations on the network.
The HiPath Wireless Controller functions like a standard router, except that it is configured to
route only network traffic associated with wireless connected users. The HiPath Wireless
Controller can also be configured to simply forward traffic to a default or static route if dynamic
routing is not preferred.
