5. It may be requirement to share ISP bandwidth between Guest HSIA and Hotel Admin
networks, or have each network available as a fall-back network for the other. Both scenarios
can be handled with the Nomadix NSE.
6. It may be desirable to have certain users connected to a particular ISP link, and other users
connected to a different ISP link. Nomadix NSE releases 8.2 provide a "preferred WAN" radius
attribute (VSA). For example, paying users may be connected to an expensive high-quality
link, with free users connected to a lower-quality link, with link failover still available if the
preferred link fails.
Some examples of typical common deployment scenarios are outlined below: These are just
examples and other deployment scenarios can be handled, as well.

Load Balancing across Multiple Low Speed Links

In this example, an establishment has access to only low-speed, DSL-based ISP circuits and
wishes to aggregate five such links together. The Nomadix NSE is configured with load
balancing between all links.

Failover to Standby ISP Link

In this example, the organization has a high-quality 100M Ethernet service. But to guarantee
continuous HSIA service, the organization has a back-up ISP service from a low-cost wireless
