With wireless increasingly becoming the primary means of access for end users, it is essential that any Software-Defined Networking (SDN) strategy encompasses the complete enterprise network including wireless and user mobility.
Avaya’s holistic software-defined networking architecture covers the user experience end-to-end across the entire enterprise network. It extends from the Data Center all the way to the enterprise edge, including the wireless edge enabling customers to reap the benefits of network simplicity, reliability, and virtualization. It also supports the deployment of SDN-enabled applications in a flexible manner based on specific business cases.
The primary purpose of a network is to interconnect users with their
applications, and the best networks do this reliably, efficiently, and with a high
degree of agility. Avaya SDN Fx™ comprises a single network-wide Ethernet
Fabric that extends from the Data Center to the Edge, enabling powerful
integration with applications, users and devices.
Avaya SDN Fabric AttachAvaya SDN Fabric Attach extends Avaya’s innovative Fabric technology to the
wireless edge (supported on Avaya Wireless LAN 9100 Series). SDN Fabric
Attach is an innovative, standards-based approach that solves the longstanding
challenge of how to easily and consistently connect a broad range of devices,
including conventional access switches, wireless LAN access points, video
cameras, IP phones, printers, and several other Internet of Things (IoT) devices
that can connect to the enterprise edge. It can also include servers, virtual
machines, and conventional top-of-rack switches in the Data Center.
With Avaya SDN Fabric Attach technology, the existing drudgery of manually
configuring thousands of access switch ports to get the “network ready” when
adding end-points like WLAN access points, video cameras, printers and other
IoT devices is removed and replaced with plug-and-play deployment based
automation.

The Avaya SDN Fabric Attach technology also helps in extending the power of
Avaya SDN Fabric Connect with its scalable, secure and automated layer-2
services based architecture all the way to the enterprise edge and help
provisioning elastic services across the enterprise network, both wired and
wireless.
The result of extending Fabric to the wireless edge is a simpler network that is
easier to implement and administer. Offering zero touch provisioning, it
accelerates time-to-service allowing new services or changes to services to be
implemented quickly and error-free. It also removes the complexity and
learning curve associated with deploying and operating wireless networks

Avaya SDN Fx™ Architecture
Avaya delivers the industry’s first holistic software-defined networking architecture, uniquely addressing the end-to-end relationship between applications, business logic, and networking services.
The Avaya SDN Fx architecture defines a solutions framework that enables customers to reap the benefits of network simplicity, reliability, and virtualization, and supports the deployment of SDN-enabled applications in a controlled manner as, where, and when business cases drive demand.
Avaya’s SDN Fx architecture is built upon three unique tenets:
• Automated Core – networking functions are automated using a single network-wide Ethernet Fabric
• Open Ecosystem – standardized Fabric protocols married with open interfaces and open source customization tools
• Automated Edge – extending the Fabric beyond the Data Center, to the Edge, for powerful integration with applications, users, and devices
The SDN Fx architecture extends seamlessly to the Wireless LAN including plug-and-play AP deployment, elastic Wireless service updates across wired and wireless parts of the network and fine-grained application control and optimization ensuring highest level of user experience.

uplink/trunk ports and tagging – this is all automated with the Avaya SDN Fx™
solution. Endpoints and client connections trigger auto configuration of
service identifiers, VLANs, port membership, etc. Endpoints and clients are
automatically attached to authorized services. The result is a greatly simplified
automated network that simplifies adds, moves and changes Services and
associated endpoints or users.
Let’s consider the benefits of SDN Fx in real life use case examples.
Dynamic Wireless Application Control The Avaya Wireless LAN architecture with a distributed architecture of deep-
packet inspection (DPI) based application control ensures a fine-grained
control and optimization of productivity and recreational applications. Fine-
grained control of more than 1300 applications can be automatically enforced
at the control plane layer, based on business rules centrally defined at the
Wireless Orchestration System (WOS). With this dynamic automation of
application usage at user session granularity, enterprise network administrators
can ensure that business needs are translated to network behavior ensuring
optimal user experience.
Mobility Use Case Examples
Use Case 1: Adding 100 new APs to existing WLAN network
Problem
IT resources and budgets are increasingly limited. IT managers and
administrators require simpler solutions that involve less IT intervention and
support. Consider the scenario where 100 new wireless Access Points need to
be added to an existing WLAN network to address bandwidth demands
resulting from the proliferation of user devices and applications. With a
traditional WLAN network, many manual steps are required. The IT
administrator would typically configure the wireless controller, plug the AP in,
manually configure the edge switch (that the AP is attaching to) and the
aggregation & core switches, and then finally confirm configuration alignment
between the switch, its port and the connected WLAN AP device. This process
then needs to be repeated for each AP, consuming hours if not days of a
network administrators time.
SDN Fx Solution
Avaya’s SDN Fx solution revolutionizes this process by enabling networks to be
provisioned in a fraction of the time of traditional networks. With Avaya’s SDN
Fx solution, all the IT Administrator is required to do is to configure the WLAN
Orchestration System (WOS) with AP information and policies. They then
connect the APs and all the rest is automated. The network is up and running in
seconds. The Avaya’ SDN Fx solution authenticates and authorizes the new
APs, downloads configuration data to each of the APs and auto provisions the
SDN Fx™ Components

switches. It removes the complexity and learning curve associated with
deploying wireless networks. The Avaya SDN Fabric Attach technology
automates the auto-provisioning of the switch ports to which the APs were
connected and to the rest of the network based on the wireless service
provisioned on the APs.
Mobility Use Case 2: Deploying New Services
Problem
A second common use case is when an IP administrator wishes to deploy new
services. With a traditional wireless network, the network administrator would
configure the new service on the WLAN Controller. They would then configure
the core switches followed by the edge switches and finally download the new
services from the WLAN Management system to the APs.
SDN Fx™ Solution
With Avaya’s SDN Fx solution, services can be deployed in a fraction of the
time. All the network administrator needs to do is to configure the new service
on the Avaya WLAN Orchestration System (WOS), download the new services
from the WOS to the APs in one automated sequence. The provisioning of the
associated edge and core switches is automatic and error-free reducing several
man-hours of configurations and troubleshooting in case of any errors.
Mobility Use Case 3: User Roaming / Mobility
Problem
The ability for users to roam freely within an enterprise while maintaining a high
user experience on their mobile devices is not a ‘nice to have’ – it is imperative in
current scenarios of highly mobile and distributed workforce. The challenge
with traditional networks is that roaming can be complex and it involves careful
planning. Factors such as AP to AP tunneling, tunnel explosion, throughput
limitations of controller-based solutions, subneting, guest access tunneled to
DMZ, all need to be taken into consideration. The reality is that there are often
so many pitfalls and limitations such as roaming not turned on. Or roaming
offered as a ‘best effort’ service.
SDN Fx Solution
The Avaya SDN Fx solution addresses the roaming complexity by delivering a
simpler solution – one design model that offers seamless roaming ability.
With the introduction of Avaya SDN Fabric Attach capability on the Avaya
Edge Switches and the WLAN 9100 Access Points, the network administrator
can define Wireless Access for Corporate and Personal devices as unique
services that specify the VLAN as well as Network / Application Access
Policies. The administrator either uses the Wireless LAN Orchestration System
or Identity Engines System based on the deployment type to specify these
services. Avaya SDN Fabric Attach technology then automatically extends
these services to all the edge switches in the wiring closets and across the core
switches leveraging Avaya SDN Fabric Connect Technology.
