2025 marked a turning point in the evolution of traditional corporate networks. The accelerating adoption of cloud technologies, SaaS services, distributed storage, and AI-driven agents has challenged conventional IP- and Ethernet-based models. Modern networks must now be adaptive, secure, and flexible enough to operate efficiently across distributed data environments and autonomous digital agents.

In this context, Arista, renowned for its innovative leaf-spine architecture for cloud data centers, has taken a strategic step to bridge the gap between corporate and cloud WAN connectivity, applying proven cloud principles to inter-data center and WAN links. Most importantly, Arista has opened a new chapter in SD-WAN development by joining forces with VeloCloud, a recognized leader in the field.

WAN Evolution in the Age of AI Agents

Just a few years ago, WANs were straightforward: regional offices accessed data stored in headquarters or data centers via fixed routes. The advent of SD-WAN allowed organizations to reduce reliance on MPLS and optimize costs.

Today, AI agents fundamentally change the landscape. Users are no longer just humans; autonomous AI agents can make decisions, access data, initiate transactions, analyze events, and interact with other systems. They may operate anywhere – in the cloud, on laptops, on factory floors, or even onboard aircraft. A WAN node no longer implies a physical building – it can be any device, object, or execution environment.

This new model demands dynamic, “any-to-any” connections with bidirectional traffic generated by both humans and AI agents. Data flows are unpredictable, context-driven, and task-specific, placing new requirements on network architecture, security, management, and scalability.

Arista and VeloCloud: A Unified Networking Vision

Broadcom’s strategic acquisition of VeloCloud enables Arista to enhance its portfolio with secure SD-WAN connectivity, advanced features such as SSE, and integration with SASE solutions. The combined platform merges cloud-oriented WAN architecture with robust data center, campus, and wireless networks. Optimized for AI-driven environments, VeloCloud solutions provide secure routing, dynamic traffic management, application-aware intelligence, and real-time adaptation to business needs.

The unified solution supports leaf-spine designs with multipath routing, encapsulation, encryption, segmentation, and embedded telemetry, enabling centralized WAN management across branches, cloud environments, and mobile users.

Strengthening Branch and MSP Capabilities

New VeloCloud Edge devices cater to managed service providers (MSPs) and branch offices, offering integrated security, 5G connectivity, Wi-Fi, and multi-speed Ethernet ports, supporting scalable infrastructures without compromising service quality. The portfolio includes new PoE switches (1G, 10G, 25G) and Wi-Fi 7 access points, optimized for modern remote offices connected via Cloud WAN.

VeloCloud integrates seamlessly with Arista’s wired and wireless campus solutions, the CloudEOS routing stack, and EOS-based platforms, providing maximum flexibility to meet any global WAN and LAN requirements – from client devices to the cloud.

Towards a Unified Infrastructure

Modern SD-WAN must fully integrate with corporate networks, including on-premises and cloud segments. The surge of generative traffic driven by AI models increases network load and impacts WAN architecture. Arista and VeloCloud share a vision of a unified network space – from device to cloud – connecting LAN and WAN environments into a cohesive infrastructure.

The acquisition of VeloCloud opens a new chapter for client-to-cloud architectures. By combining proven SD-WAN and SSE technologies with Arista’s zero-trust and cognitive network management vision, organizations can implement adaptive, scalable, and secure solutions for enterprises of any size in the era of AI-driven agents.
