802.11ac-ready

The next-generation wireless LAN standard – 802.11ac,

is just around the corner bringing Gigabit speeds to the

wireless network. This will present a similar challenge as

the introduction of 802.11n—the faster AP throughput

requires a forklift upgrade to the backend hardware

controllers to handle the higher throughput.

vWLAN breaks this upgrade cycle. With vWLAN’s

distributed data plane architecture, customers do not

need to upgrade controllers ever again, providing a

solution that is future proof ensuring customers can

conﬁdently adopt 802.11ac when it arrives.

Wireless Access Points

ADTRAN’s Bluesocket family of high-performance APs

is the perfect ﬁt for enterprises, educational institutions,

hospitality, and healthcare providers who are looking

to move their organisations to a pervasive mobility

environment. The Bluesocket portfolio of 1800 and 1900

Series of enterprise-class APs are completely plug-and-

play requiring no manual conﬁguration. They include

MIMO, beam-forming and high RF transmit power to

deliver industry leading throughput and performance.

Whether you want to expand wireless coverage in your

ofﬁce or deploy across an entire campus, the Bluesocket

APs are designed to meet your needs.

Second, a centralised physical controller is a

target for hackers. This device is in the data path and

therefore serves as a convenient point to intercept

trafﬁc. vWLAN eliminates this vulnerability by keeping

the data sessions on the LAN. Only control trafﬁc is

centralised. And this centralisation occurs in the

enterprise data centre as opposed to a single server.

Reliability

ADTRAN’s vWLAN brings wireless reliability to a whole

new level. In vWLAN, the user data stream or data plane

is separated from the control information about the

data session. This separation of the control plane and

data plane increases reliability. In the conventional

controller-based approach, any failure in the control

plane interrupts the data plane. In vWLAN, the data

session is the priority. The control plane can be com-

pletely lost and the user data sessions remain intact.

This separation of control and data allows vWLAN

to support hitless failovers. A secondary virtual control

instance can back up the primary control. If an access

point loses connection with the primary virtual control

instance, it will realign with the secondary control. This

re-establishment of the control plane takes place with

zero packet loss to any of the data sessions.
