IdentiFi Wireless provides an easy, low cost way to deploy 802.11ac/abgn solutions, delivering cost-effective pricing, wired/wireless integration, and low TCO while openly supporting a broad range of mobile voice, video, and location-based applications to drive enterprise productivity and reduce the overall cost of mobility. With the ability to deliver both centralized and distributed traffic forwarding by application, IdentiFi Wireless Appliances enable a flexible, cost-effective path to deploying 802.11ac/abgn for the enterprise. Backed by industry-leading global support and services, IdentiFi Wireless solutions enable customers to leverage existing investments and avoid forklift upgrades.


Virtual Network Service (VNS) - An Adaptive WLAN Architecture

Most WLAN solutions force network administrators to choose between a centralized or distributed architecture. A significant advantage of IdentiFi Wireless Appliances is that they can support both deployment models simultaneously, offering significant flexibility benefits over other solutions. Network administrators can select how traffic will be handled on a per-SSID basis, without any restrictions, so that the wireless LAN infrastructure can adapt to business requirements and applications.

A centralized architecture requires all traffic to be backhauled to a centralized Appliance. With the higher data rates of 802.11ac and 802.11n APs, traffic loads on the wired network can be much greater than those created by legacy 802.11a/b/g APs. Depending on the size of the WLAN deployment and how much data is forwarded to the centralized Appliance, significant congestion may result.

A fully distributed deployment eliminates backhauling traffic to a wireless Appliance but increases the processing complexity for real-time mobile applications that require seamless cross-subnet roaming (e.g. VoWLAN). This can force IT managers to either create a large broadcast domain or apply many VLANs.

IdentiFi Wireless Virtual Network Services control traffic flow by allowing traffic to be backhauled to a wireless Appliance or switched locally at the AP on a per SSID basis. With local switching, the AP is still managed centrally by the wireless Appliance, but data is not backhauled to the wireless Appliance. This improves responsiveness and ensures that traffic does not unnecessarily traverse costly WANs or contribute to bottlenecks at aggregating switches. A VNS also provides role-based policies providing security, NAC, mobility, and QoS priority that can be implemented on a per user and per application basis.

Integrated Management and Control Across Wireless and Wired Networks

Web-Based Centralized Management Via Wireless Assistant

The Wireless Assistant provides network administrators with a centralized web-based interface designed to easily manage both infrastructure and services. Hosted on the wireless Appliance, this interface allows network administrators to separately configure, enable, or disable each AP or group of APs. The wireless Appliance consolidates data received from across the network to provide meaningful statistics in easy-to-read reports. Additionally, a number of standards-based management tools are available to facilitate integration of the WLAN infrastructure with enterprise management applications. For large networks with multiple wireless Appliances the optional OneFabric™ Control Center Management Suite can be used to collect and manage data for a centralized view of the entire WLAN.

Multi-Appliance Management

NetSight ™ provides centralized management for the IdentiFi Wireless portfolio, consolidating management information from across the entire WLAN for a global network perspective. The solution is enhanced by the addition of IdentiFi Radar Intrusion Prevention System (WIPS) option which provides sophisticated wireless intrusion prevention and location assessment capabilities. Wired and wireless network integration is further enhanced by the visibility of all the wireless elements through the OneFabric™ Control Center Management Suite. Integration between OneFabric™ Control Center and the IdentiFi Wireless portfolio provides end-to-end visibility of wireless Access Points, Appliances, and wireless clients from the OneFabric™ Control Center Console. The integration delivers improved network management efficiency and wired/wireless infrastructure topology mapping and visibility for network administrators. Further integration with OneFabric™ Control Center Inventory Manager effectively centralizes distribution of software and tracking of configuration changes.

Integrated Security

Wireless IDS and IPS enhances security with embedded wireless intrusion prevention through Extreme Networks Radar. When deployed in conjunction with the IdentiFi Intrusion Prevention System (IPS), full packet inspection, adaptive signature pattern matching, protocol analysis, and behavioral anomaly detection are delivered for both wired and wireless users. Further, OneFabric™ Control Center Mobile IAM identity based policy privileges are unified across the wired and wireless infrastructure to deliver role-based access control – regardless of connectivity method.

The Mobile IAM policies ensure only the right users have access to the right information, from the right place, at the right time. Third party authentication systems can also be integrated with the use of the External Captive Portal interface.

High Performance & High Availability

IdentiFi Wireless delivers the perfect combination of high-performance and high-availability demanded by today’s wireless applications. By combining unique voice optimization features and the latest in industry standards, IdentiFi Wireless provides enterprise grade reliability for all users.

High Scalability

The IdentiFi Wireless portfolio supports from a single AP to 2,000+ APs per wireless Appliance, providing linear scalability from small to large wireless deployments. In addition, wireless Appliances can be networked to scale beyond the limits of a single Appliance or availability pair to offer a multi-wireless Appliance mobility zone. Mobility zones enable seamless roaming across a large number of wireless Appliances while still delivering real-time session-availability services without requiring the purchase of additional AP licenses for redundancy.

IdentiFi Wireless provides true end-to-end Quality of Service (QoS) with each Appliance and AP supporting native IP prioritization (DiffServ, TOS, Precedence), Ethernet 802.1p, as well as 802.11e’s WMM and TSPEC wireless QoS standards. IdentiFi Wireless devices support distinct queues on all interfaces, whether wired or wireless.

When voice and data traffic are running on the same AP, voice traffic can be prioritized to ensure minimal delay and jitter for optimal voice quality. The wireless Appliances are able to translate WMM prioritized traffic to existing QoS prioritization schemes on the wired network (TOS, DSCP, etc.).

Fast and Secure Roaming For Seamless Voice and Data Mobility

IdentiFi Wireless Appliances manage sessions centrally to ensure fast, secure, and seamless roaming as users and devices move Wireless Appliance – Data Sheet 4 throughout the radio coverage range of each AP. Seamless roaming greatly improves productivity by providing true mobility across the enterprise, all transparent to the user.

The Wireless Appliances use industry standards to deliver fast and secure roaming. 802.11i pre-authentication (Pre-Auth) ensures that the user is authenticated to adjacent APs before entering their coverage range, preserving voice calls as users move throughout the enterprise. Opportunistic Key Caching (OKC) is also a supported mechanism which greatly improves device roaming times.

High Availability and Self-Healing

Redundant IdentiFi Wireless Appliances can be deployed across the network and operate in failover or load sharing mode. Access points can be configured for fast-failover mode to allow configuration and service restoration (in tunnel mode) in less than two seconds, thus enabling user sessions to continue uninterrupted. When switching traffic locally, APs continue to provide service even when the link to the wireless Appliance is severed and can be configured to resume service should a power outage force them to restart.

IdentiFi Wireless APs also feature Dynamic Radio Management, which enables the network to automatically adapt to changes in the RF environment or failure of any individual APs, ensuring availability and performance to users. Each wireless AP continuously monitors channel use, signal to noise ratio (SNR) for interference, and the receive power of neighboring APs (IdentiFi or third party) to adjust their channel and transmit power.
