vWLAN Beneﬁts

Eliminates the cost and constraints of a physical controller:

Eliminating the physical controller triggers a number of advantages

not the least of which is cost. Both the initial CAPEX and the

ongoing OPEX associated with the controller are gone.

Enforces network security at the edge: vWLAN takes advantage

of intelligent access points and enforces security policies at the

edge. A full stateful ﬁrewall is conﬁgured and managed centrally

but the policy is enforced at the access point.

Provides seamless, cost-effective scaling: vWLAN separates

the control and data plane. This allows for separate scaling and

greater capacity. Adding more access points (data plane) does

not drive an increase in the control plane. Likewise, adding more

locations or more users does not require an additional investment

in the control plane.

Optimises Performance: With vWLAN, system capacity is

no longer determined by the backplane capacity of the controller;

rather, capacity is a function of the aggregate throughput of

the APs.

Flexibility: Virtualisation permits a single application to run

independent of the underlying server infrastructure. A vWLAN

control instance in one city can control access points anywhere in

the world.

Reliability: vWLAN can be conﬁgured in a high availability

arrangement such that a failover can take place with zero packet

loss. Reliability is based on the dependency of the data centre

as opposed to a single purpose controller.

Businesses of all Sizes

vWLAN provides a ﬂexible solution that can

operate in multiple deployments from a branch

ofﬁce to a large campus environment while offering

a lower cost of ownership and optimal performance.

Remote ofﬁces deployments are demanding more

from wireless LAN solutions and vWLAN responds

by integrating ﬂexibility into the security and data

forwarding modules.

Wireless LAN systems, especially in large campus

environments, are expected to provide minimal

downtime as they support a signiﬁcant number of

users and critical applications. vWLAN addresses this

requirement by providing a seamless, high availability

solution that is transparent to the wireless users

(with zero packet loss) while also providing ﬂexible

deployment options.

Virtualisation

By virtualising the centralised management and

control function and making it available on a

hypervisor, like VMware, ADTRAN removes

100 percent of the controller hardware, vastly

reducing capital costs and TCO. This in

conjunction with the other beneﬁts that

virtualisation provides like, speedy deploy-

ments, inﬁnite scale and virtual consolidation

across the organisation, makes vWLAN on

VMware the most powerful and complete

choice for an efﬁcient, secure, high perform-

ing and cost-effective wireless LAN solution.
