Introduction

SD-WAN is a cellular-optimized network service based on a zero-trust foundation that enhances WAN resilience and quality of experience (QoE) by optimizing traffic over multiple physical or logical connections including, wired, 5G/LTE, satellite, Wi-Fi as WAN, private APNs, and 5G standalone network slices.

SD-WAN benefits:

- Designed on a simple, modern zero-trust foundation that obscures IP addresses, is deny all by default, and where resources must be defined before they are accessible.
- Supports traffic optimization over physical and logical connections, including being the first SD-WAN solution to support 5G network slicing.
- Implementation of application-based policies network-wide in a few simple steps.
- Efficient and cost-effective operation over cellular by considering cellular-specific attributes when steering traffic (for example, signal strength) in addition to latency, loss, and jitter.
- Preserves bandwidth by using inline traffic rather than artificial traffic to measure WAN performance.
- Offers enhanced QoE over lossy links through Forward Error Correction (FEC).†
- Ability to intelligently bond multiple WAN interfaces together to increase resiliency and provide more granular control over traffic.†
- Deep visibility into latency, loss, and available bandwidth from the edge to the cloud.
