Arista introduced major upgrades to its Cognitive Campus portfolio today, highlighted by a new mobility architecture and expanded AI-driven operations. The company unveiled Arista Virtual Ethernet Segment with Proxy ARP (VESPA), a controller-less mobility framework built to support extremely large Wi-Fi domains. Arista also advanced its AVA agentic-AI platform and added ruggedized EOS-based switches designed for harsh industrial and outdoor environments.
VESPA targets enterprises facing exponential growth in clients and IoT devices by applying data-center network design principles to the campus. The architecture supports roaming domains with more than 500,000 clients and sub-second failover, while removing traditional controller bottlenecks. Arizona State University partnered with Arista to help shape and validate VESPA as part of its shift to controller-less Wi-Fi. The AVA platform—Arista’s Autonomous Virtual Assist system—provides an AI framework built on EOS and the NetDL data lake, enabling network-wide reasoning, event correlation, and conversational troubleshooting across wired, wireless, security, and data-center domains.
Arista further expanded its campus switching lineup with two ruggedized platforms built for industrial and outdoor deployments: a 20-port DIN-rail switch (IP50) and a 1RU 24-port switch (IP30). Both support multi-gig interfaces, 90W PoE for next-generation devices such as Wi-Fi 7 access points and outdoor security cameras, and full EOS and CloudVision integration. All new capabilities and platforms are slated for general availability in Q1 2026.
• VESPA scales campus mobility domains to 500,000+ clients
• Sub-second roaming and controller-less design
• AVA provides an AI reasoning and automation framework built on EOS + NetDL
• Supports multi-domain event correlation, Ask AVA conversational troubleshooting, and automated RCA
• New ruggedized campus switches: 20-port DIN-rail (IP50) and 24-port 1RU (IP30)
• Designed for harsh environments and high-power PoE, including Wi-Fi 7 APs
• General availability expected Q1 2026
“Arista is experiencing continual momentum in the campus, as customers see the benefit of a single, consistent network experience across all domains,” said Todd Nightingale, President and COO at Arista.
🌐 Analysis: Arista continues to extend its cloud-networking model into the campus, using EOS, NetDL, and now AVA to unify operations across every domain. VESPA’s controller-less approach represents a notable challenge to legacy WLAN architectures from Cisco, HPE Aruba, and Juniper, particularly at very large scale. With AVA’s agentic-AI capabilities and MCP integration, Arista aims to position its campus portfolio as an open, AI-driven alternative to closed vendor tooling.
