Virtual Network Services

(VNS)

The Virtual Network Services (VNS) technique is Siemenss means of mapping wireless

networks to the topology of an existing wired network. When you set up Virtual Network

Services (VNS) on the SCALANCE IWLAN Controller, you are defining subnets for groups

of wireless users. This VNS definition creates a virtual IP subnet where the SCALANCE

IWLAN Controller acts as a default gateway for wireless devices. This technique enables

policies and authentication to be applied to the groups of wireless users on a VNS, as well

as the collecting of accounting information. When a VNS is set up on the SCALANCE

IWLAN Controller, one or more Wireless APs (by radio) are associated with it. A range of IP

addresses is set aside for the SCALANCE IWLAN Controller's DHCP server to assign to

wireless devices.

Wireless AP The Wireless AP is a wireless LAN thin access point (IEEE 802.11) provided with unique

software that allows it to communicate only with a SCALANCE IWLAN Controller. (A thin

access point handles the radio frequency (RF) communication but relies on a controller to

handle WLAN elements such as authentication.) The Wireless AP also provides local

processing such as encryption. The Wireless AP is a dual-band access point, with 802.11a/

b/g/n radios.
