3 SDN Fx Components SDN Fabric Connect Innovative Ethernet Fabric that enabled the 2014 Sochi Olympic Games and delivers the automated Core SDN Fabric Attach Extends Fabric Connect to the edge (wired/wireless switches, IoT devices etc.) SDN Fabric Extend Supports the interconnection/tunneling of Fabric Connect connectivity over third party IP-based networks. Fabric Extend can be used to deliver service elasticity, create new connectivity options, and provide additional resiliency SDN Fabric Orchestrator Fabric Orchestrator is a core component that enables orchestration and programmability. Designed as an easy-to-deploy solution leveraging Fabric Attach for touchless provisioning, the Fabric Orchestrator provides for configuration, provisioning, monitoring, and policy management services, delivering these via a single pane of glass user interface SDN Fabric ONA The Avaya Open Networking Adapter (ONA) initiative delivers a family of small form-factor devices that act as a bridge between any Ethernet-equipped device and the Fabric Connect private cloud. Simply connect the business end-point via an ONA and Fabric Attach functionality takes care of the rest; provisioning is automated, and centrally defined service parameters are applied. 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 deeppacket inspection (DPI) based application control ensures a fine-grained control and optimization of productivity and recreational applications. Finegrained 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 avaya.com 3

4 Why Avaya SDN Fx? Addresses the end-to-end relationship between applications, business logic, and networking services. Benefits from a pragmatic foundation openness and standards Provides service agility without increasing complexity. Addresses the Network Edge, where users and their devices begin their interaction with applications. Supports traditional access technologies and the variety of emerging end-points: video cameras, wireless access points, user-centric devices, sensors, scanners, several other Internet of Things (IoT) devices, vswitches VM Hypervisors, as well as conventional third-party end-points, 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. avaya.com 4
