Problem Statement

As enterprises become more distributed and applications increasingly move to the Cloud, traditional WAN architectures are struggling to keep pace. Legacy MPLS-based networks are often rigid, expensive, and lack the agility needed to support dynamic workloads, remote users, and modern business models.

To address these limitations, organizations are rapidly turning to Software-Defined Wide Area Networking (SD-WAN) as a smarter, more flexible alternative. SD-WAN offers intelligent traffic routing, centralized control, improved security, and better application performance across diverse network types, making it essential for today’s digital-first enterprises.

Customer Requirements

A US-based OEM specializing in enterprise networking sought a custom SD-WAN platform tailored to meet the connectivity needs of mid-market enterprises. Their goal was to introduce a compact, high-performance SD-WAN hardware solution that could replace legacy VPN routers and supports multi-WAN and zero-touch provisioning features.

Key customer requirements included:
  • Optimized hardware for SD-WAN workloads (secure, multi-core processing)
  • Compact, thermally efficient mechanical design
  • Multi-WAN interface support (4G/LTE, Ethernet, USB, Wi-Fi)
  • Zero-touch provisioning and secure firmware boot
  • Integration-ready design for their existing SD-WAN software stack

Key Challenges Faced by VVDN

  • Form Factor & Thermals : Designing a fanless, compact enclosure capable of dissipating heat from high-performance networking components.
  • High-Speed Interface Routing : Ensuring signal integrity and EMI performance while supporting multiple WAN interfaces and high-speed peripherals.
  • Power Efficiency : Optimizing the design to operate reliably under low power budgets across industrial temperature ranges.
  • Customer-Specific Layout Constraints : Accommodating layout preferences and internal module placements to ensure smooth software integration.
