주요 비디오: Arista Networks 인지 Wi-Fi

Cloud Vision Wi-Fi (CV Wi-Fi) is at the core of Arista’s cloud-native approach to enterprise Wi-Fi networks. It enables centralized management of APs which remarkably simplifies policy management and provisioning of Wi-Fi 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 Wi-Fi 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 Wi-Fi 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 Wi-Fi.

Key Features

Cognitive Management Plane

CloudVision Wi-Fi 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 Wi-Fi 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 Wi-Fi 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 Wi-Fi’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 Wi-Fi 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 Wi-Fi 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 Wi-Fi supports flexible end user access management in enterprise Wi-Fi 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.
