SD-WAN & WAN Architecture

Intelligent WAN design that connects distributed environments without the complexity and cost of legacy MPLS.

Practice Area Overview

WAN Architecture for How Organizations Actually Work

SD-WAN gives organizations the flexibility to use multiple transport types — broadband, LTE, MPLS — under a single policy-driven management plane. QVIA designs SD-WAN architectures from the ground up: transport selection, overlay design, QoS policies, and security integration. For organizations managing multiple sites, remote workforces, or cloud-first strategies, SD-WAN is often the highest-leverage network investment available. We design for your actual traffic patterns and site requirements — not a reference architecture that assumes your environment looks like everyone else's.

Technical Capabilities

What We Deliver in This Practice

Multi-transport design (broadband, LTE, MPLS hybrid)

Overlay network design and tunnel management

Application-aware routing and QoS policy

Zero-touch provisioning for remote and branch sites

Security integration (SASE, cloud-delivered firewall)

Cloud on-ramp architecture (AWS, Azure, GCP)

WAN performance monitoring and SLA visibility

Site-to-site VPN consolidation

Migration planning from legacy MPLS to SD-WAN

Why It Matters

What's at Stake at This Layer

Lower Cost, Higher Flexibility

MPLS costs are real and rising. SD-WAN lets you use cheaper broadband transport while maintaining the reliability and application-performance policies you need — and adding transport options when requirements change.

Security Built Into the WAN

Modern SD-WAN platforms integrate security natively. We design security into the WAN architecture — SASE, cloud-delivered firewall, encrypted overlays — rather than treating it as an add-on after the network is running.

Cloud-Ready WAN

Legacy WAN architectures route cloud traffic through a central hub, adding latency for every cloud application. SD-WAN routes cloud traffic directly from each site, which is where it needs to go.
