Wi-Fi has become the primary access mechanism in today’s enterprise networks. Ensuring users have seamless connectivity and smooth application experience requires the Wi-Fi part of the network to work flawlessly. In addition to providing the basic connectivity, it needs to provide actionable intelligence to network administrators for addressing immediate issues and to optimize the network for the ever changing network conditions.

Arista’s CloudVision Wi-Fi provides network administrators the tools required to ensure that the Wi-Fi network is running flawlessly, pre-empt issues that could degrade user experience, test the network on demand and as per pre-defined schedule and finally, provide actionable insights, in case users do have less than the smooth application experience they expect. Ensuring the optimal function of the deployed Wi-Fi network and achieving the smallest “mean time to resolution” in case of any reported issues are the key goals of CloudVision Wi-Fi.

Arista’s Cognitive WiFi solution leverages the power of the cloud and the massive data sets available across its customer base to continuously perform supervised and unsupervised learning required to apply AI concepts to decipher Wi-Fi users’ application experience. Arista uses inference models to arrive quickly at the root cause of any poor experience and proactively provides this information to the network administrators along with suggested remediation.

Cognitive WiFi

Arista’s Cognitive WiFi solution’s distributed control plane allows seamless and limitless scaling, removes any single points of failure and ensures amazing user experience. With best-of-breed hardware, including the latest Wi-Fi 6 AP family; the best Wireless Intrusion Prevention System that the industry has to offer and a robust Guest management and analytics solution, Arista’s CloudVision Wi-Fi provides the best value for money solution for Enterprise Campus deployments. CloudVision WiFi’s all-in licensing policy ensures that customers can enjoy all the benefits of this top of the line solution without having to worry about missing out.

Cloud Vision WiFi (CV WiFi) is at the core of Arista’s cloud-native approach to enterprise WiFi networks. It enables centralized management of APs which remarkably simplifies policy management and provisioning of WiFi networks.. At the network edge, APs are equipped with distributed algorithms to handle control plane functions locally. This decoupling of management and control planes, along with a flexible data plane that allows wireless access points to provide customizable traffic redirection at the network's edge, results in a more robust network, without a single point of failure. Thus, CV WiFi enables seamless scaling of the network from a few to 1000s of APs.

With virtually unlimited and elastic availability of storage and compute resources, the Arista WiFi solution eliminates artificial boundaries inherent in controller-based WLAN architectures. Naturally, it enables many innovative, previously unforeseen applications in big data analytics, machine learning and cognitive computing in the context of WiFi.

Key Features

Cognitive Management Plane

CloudVision WiFi is powered by a cognitive management plane which simplifies configuration and troubleshooting while delivering richer telemetry to network administrators. The innovative cognition plane uses AI and ML techniques to provide root cause analysis and proactive problem resolution options to reduce the mean time to resolve problems, minimizing network troubleshooting effort and reducing total cost of ownership.

Network Baselining Baselines network behavior and automatically detects and highlights anomalies, using ML algorithms.
Root Cause Analysis Engine Automatically detects and classifies WiFi clients’ connection failures and pinpoints the root cause in real-time.
Single Client Inferencing Identifies clients facing poor QoE, based on RF, network and application KPIs and performs root cause analysis for specific clients.
Automatic Packet Capture Proactively captures packet traces to help diagnose problems; traces are stored alongside related failures or symptoms to simplify troubleshooting later.
Client Emulation and Network Profiling Takes advantage of the multi-function radio, present in most Arista WiFi APs, turning it into a client to run a wide variety of tests and proactively identify problems before users do.

The Cognitive Management Plane is driven by Arista’s NetDB, a state-based, cloud-hosted, network-wide database that collects real-time data streamed from wired and wireless devices for cognitive analytics. CloudVision WiFi’s capabilities can be extended further by integration with 3rd party applications using OpenConfig and Arista’s ReST API framework.

Wireless Intrusion Prevention

With a multi-function radio acting as a dedicated wireless intrusion prevention (WIPS) sensor, wireless threats are detected and blocked almost instantly in your network. CV WiFi works with the APs, which are powered by patented techniques such as Marker PacketsTM, to enable surgical over-the-air intrusion prevention, automatically and accurately creating alerts and classifying wireless threats. CloudVision WiFi uses behavior based detection of threats; rather than a signature based approach; to enable zero day protection without chasing exploits, tools and their signatures.

Secure Client Access

CV WiFi supports flexible end user access management in enterprise WiFi networks by enabling seamless integration with leading identity management solutions such as Aruba ClearPass, ForeScout NAC, Cisco ISE etc. Arista Guest Manager provides multiple ways for guest access in the enterprise including Guestbook, vouchers, OTP-based etc.
