Arista Networks Cognitive WiFi With CloudVision Enhances Connectivity on College Campuses

Arista Networks announced the next phase in its campus architecture, changing the way enterprises rebuild campus networks in the future. Arista’s Cognitive Campus unifies wired and wireless campus networking, applying modern software-driven cloud principles. Arista Cognitive WiFi eliminates legacy WiFi controller bottlenecks to reduce operational costs with higher reliability through a cloud-based, cognitive model.

“Legacy WiFi solutions focus on basic connectivity and provide little insight into performance. Arista’s Cognitive WiFi with Arista EOS and CloudVision focuses on the customer’s experience, ensuring application performance and reachability,” says John McCool, Chief Platform Officer, Senior Vice President of Engineering and Operations for Arista.

Introducing CloudVision for Campus
Traditional campus networks suffer from complex bottlenecks brought on by the myriad of platforms, operating systems, proprietary features, and network management tools. Coupled with the explosive growth of IoT and endpoints as well as the requirement for workloads, users and devices to be connected anywhere, the operational costs of managing these complexities become prohibitive.

Arista CloudVision, built on the Cognitive Management Plane (CMP) engine, is a proven and powerful platform for turnkey orchestration, provisioning, and telemetry. Born initially in the datacenter era, CloudVision now extends the same common operational model to the campus providing unified wired, wireless, and datacenter management.

Wired and wireless campus networks must cope with ever-increasing endpoint devices necessitating the understanding of endpoint behavior. CloudVision’s latest feature Device Analyzer provides inventory and deep flow analysis of all connected devices. Campus administrators can access device type, connectivity method, location and communication patterns. This visibility enables an administrator to identify unauthorized traffic and compromised endpoints. Since CloudVision spans the datacenter and the campus, customers can leverage a single platform for end-to-end troubleshooting.

Arista Delivers Cognitive WiFi
With the acquisition of Mojo Networks, Arista now integrates the wireless edge via the CloudVision platform. The Cognitive WiFi architecture is tailored to enable an Arista access point portfolio in a controller-less wireless network. These AP solutions are available in disaggregated options harnessing the power of cloud, machine learning and cognitive computing to deliver great experiences to WiFi users. Arista’s Cognitive WiFi delivers massive scalability, and a linear pay-as-you-go pricing model, providing a predictable total cost of ownership path. CloudVision WiFi is based on a similar CMP model for cognitive analytics unifying the operational experience across wired and wireless. CloudVision WiFi enhances real-time insight into the experience of WiFi clients to connect and utilize the network. The Client Journey is a set of dashboards that help operators diagnose client connectivity, track availability of network services and identify root cause of WiFi issues with live and historical telemetry data for proactive assessment of client to application performance.

Arista Cognitive Campus includes a suite of WiFi Tracer tools for wireless security, reachability, and network health diagnostics. integrated Wireless Intrusion Protection System (WIPS) protects networks against rogue APs, honeypots, and implements device classification to determine authorized client devices connecting to unauthorized APs. Additional WIPS scanning is accomplished via a dedicated third radio which can also perform various network performance and health diagnostics. The AP can simulate a client device–association and authentication instrumenting identity and access (AAA and DHCP/DNS) latencies, connectivity to the upstream network, voice calls to calculate MOS score and network throughput. These automated tests can be pre-scheduled without administrator intervention ensuring business ready WiFi. CloudVision WiFi applications fuses Arista access points with cloud networking spines and splines for a seamless topology view.

Product Availability
The Arista Cognitive WiFi software and family of disaggregated access points is available now, including the new Client Journey and WiFi Tracer feature sets. Arista’s CloudVision for Campus is available in Q4 2018 for early field trials and general availability in the first half of 2019.
