This guide details the methodology of Quality of Service (QoS) configuration and testing on Dell Networking switches for the Microsoft Unified Communications Open Interoperability Program (UCOIP).

Organizations are increasingly turning to Microsoft Lync to drive down costs and drive up worker productivity through an integrated solution for Unified Communications and Collaboration (UC&C). Microsoft Lync deployments are increasing dramatically as business leaders realize the value of deploying an integrated platform for voice, video, Web conferencing, instant messaging, collaboration, presence and private branch exchange (PBX) replacement

Organizations must deliver business-grade voice communications to both wired and mobile users so that users can access a rich set of communications and collaboration tools that are accessible at their desks or on the move. Without a solid network infrastructure, the quality of experience, user adoption and, ultimately, return on investment will suffer.

Dell teams with Microsoft to provide comprehensive UC&C solutions that support high-quality service delivery. In addition to the Dell solutions being optimized to deliver an exemplary user experience, these solutions also undergo testing for Microsoft Lync certification. The solutions are validated based on Microsoft recommended best practices as well as our own real world experience. For example, Dell has designed reference architectures to serve as starting points for full Microsoft Lync implementation. Dell solutions include storage, networking and servers as well as endpoint devices on the desktops and in the hands of users around the world.

The Microsoft UCOIP test plan includes voice and video quality tests with simulated WAN impairment. To validate QoS configurations and show Microsoft Lync performance improvement, background traffic is supplied to each PC and switch in the test topology. This guide shows how QoS was configured and presents the Microsoft Lync quality and performance metrics that were achieved.
