Silver Peak VoIP withstands ‘torture test’ for quality

04 Oct 18

Silver Peak’s Unity EdgeConnect SD-WAN edge platform has earned the Miercom Performance Verification certification following a series of real-world Voice over IP (VoIP) test scenarios.

The EdgeConnect platform successfully maintained high-quality VoIP performance over consumer-grade broadband links as increasing levels of packet loss and network congestion were introduced across single and bonded dual link configurations.

Silver Peak engaged Miercom, an independent network test lab, to design a series of real-world VoIP test scenarios to simulate the various conditions broadband links exhibit when increasing levels of packet loss and network congestion are introduced.

Voice quality was measured over the links using the MOS (Mean Opinion Score) industry standard for each scenario to determine if EdgeConnect could sustain a business-acceptable MOS performance score of greater than 3.0 using single and dual consumer broadband links.

The tests were conducted with and without the advanced Silver Peak High Availability (HA) tunnel bonding and path conditioning capabilities enabled.

As enterprises increasingly leverage the internet to connect users to cloud applications, they face a trade-off in their ability to deliver reliable high-quality voice over broadband.

Basic SD-WAN offerings force compromise as they require higher cost transport services such as MPLS or Direct Internet Access (DIA) to deliver an acceptable user experience.

This ultimately holds enterprises back from realising the transformational promise of SD-WAN and the Cloud.

“Silver Peak is once again placing the industry on notice following last year’s gruelling network Torture Test, challenging any vendor to submit their product to the same MOS test scenarios for VoIP performance over consumer-grade broadband,” says Silver Peak vice president of product marketing Derek Granath.

“Only EdgeConnect consistently delivers the highest QoEx for VoIP over broadband, maintaining a MOS of greater than 3.0 even under severely impaired WAN conditions.”

The Miercom test validates the clear differentiation of Silver Peak EdgeConnect as the only SD-WAN edge platform to deliver toll-quality voice over consumer broadband under real-world network conditions, ensuring the highest quality of experience (QoEx) for end users and IT.

“The Silver Peak Unity EdgeConnect SD-WAN edge platform provides proven quality voice communications in times of peak congestion or a complete service blackout condition using its High Availability tunnel bonding and path conditioning,” says Miercom CEO Rob Smithers.

“Based on our testing, even with consumer-grade internet links, the EdgeConnect platform can tolerate upwards of 20% loss on both connections, setting an impressive bar.”
