SD-WAN 101: Ensuring Peak Network Performance and Service QoE

As with any new technology, SD-WAN does not come without challenges. The network infrastructure needs to be well-tested to be able to provide the five-nines reliability required for business-critical applications. Testing robustness and ensuring security of the network is extremely critical since the cost of downtime for an enterprise network is very high. Read this paper to better understand the pre-deployment network infrastructure validation and post-deployment SLA and performance monitoring required to ensure successful SD-WAN implementations.

Focus on 5G Pre-Silicon to Cloud Testing

No one would argue that networks are becoming more complex. Enterprise customers will adopt advanced mobile services where needed. Whether that is served by hybrid public/private cloud, public network, or private network will be decided by the business case and available facilities. Operators have a heavy focus and expectation on delivering greater energy efficiency, network optimization, and increasing the operational effectiveness of automated processes at a network-wide scale.

Network Emulators Catalog

This catalog highlights Keysight’s Network Emulator 2 and Network Emulator 3 solutions, enabling precise replication of real‑world network impairments across 100 MbE to 100GE Ethernet. It provides performance details, use cases, architecture capabilities, and supporting tools for validating application robustness, interoperability, and network resilience before deployment.

Why Network Emulator 3?

In this video, meet Keysight Network Emulator 3 — the fastest interface speed network emulator supporting 100GE, 25GE, and 10GE Ethernet impairment platforms. Built with application-aware emulation engines, it delivers precise control over network impairments such as latency, jitter, and packet loss, allowing you to test application performance under real-world network conditions with unmatched accuracy. Watch how it helps you uncover hidden performance issues, debug application behavior, reduce deployment risks, accelerate release cycles, and ensure consistent user experiences before connectivity disruptions ever reach your users.
