One of the things we like to discuss on Packet Pushers are use cases—why you’d want to use a specific technology in the real world. Today, we’re going to discuss, with our sponsor Sonus, how to enforce QoS end to end across a network to support real-time communications.
If you’ve built a campus QoS scheme, you think in terms of DSCP marks, low-latency queuing, and so on. But the reality is these schemes are static and designed for peak loads in the hope that UC traffic doesn’t exceed those static allocations.
So what if there was a way to build out a QoS prioritized path in real time? What if, when the call was stood up, the path between the end points had traffic prioritization configured automatically?
Sonus’s VellOS allows us to do this and more. VellOS is a network operating system that allows you to fully automate flows through a network, so you can control bandwidth, packet marketing, MPLS values, and more to ensure voice and video calls get the highest quality available.
On today’s show, we’re going to drill into how VellOS works, including its use of OpenFlow, and its integration with Microsoft’s UC SDN API. Joining us for today’s conversation are Kevin Isacks, VP of Engineering at Sonus; and Dan Malek, Software Engineering Fellow at Sonus.
