2.3.3 Virtual Network Services
Virtual Network Services (VNS) provide a versatile method of mapping wireless
networks to the topology of an existing wired network.
In releases prior to V7.0, a VNS was a collection of operational entities. Starting
with Release V7.0, a VNS becomes the binding of reusable components :
•WLAN Service components that define the radio attributes, privacy and
authentication settings, and QoS attributes of the VNS
•Policy components that define the topology (typically a VLAN), filter rules,
and Class of Service applied to the traffic of a station.
Figure 4 illustrates the transition of the concept of a VNS to a binding of reusable
components.
Figure 4 VNS as a binding of reusable components
WLAN Service components and Policy components can be configured separately
and associated with a VNS when the VNS is created or modified. ALternatively,
they can be configured during the process of creating a VNS.
Additionally, Policies can be created using the Enterasys NetSight Policy
Manager and pushed to the HiPath Wireless Controller. Policy assignment
ensures that the correct topology and traffic behavior are applied to a user
regardless of WLAN service used or VNS assignment.
When VNS components are set up on the HiPath Wireless Controller, among
other things, a range of IP addresses is set aside for the HiPath Wireless
Controller’s DHCP server to assign to wireless devices.
