Microsoft have released a new version to the [Amazing] Lync Network Planning, Monitoring and Troubleshooting guide.
I have recently passed 74-335 Network Readiness Assessment and must say that understanding the Microsoft Network Assessment Methodology along with this guide was absolutely crucial.
Now at v2.3, it seems to have been updated with additional Wi-Fi and QoS Guidance, the following extract has been taken from the download site;
“An updated version of the Networking Guide is now available including the new Microsoft Call Quality Methodology Scorecard for Lync Server. This scorecard should be used to implement the Lync Call Quality Methodology or CQM as outlined in Appendix C. CQM is a holistic way to systematically define and assert call quality based upon the methods outlined in the Networking Guide. CQM divides a Lync implementation into ten discrete areas that impact quality, defining targets and a remediation plan for each one. CQM is a framework to tackle call quality problems – you can modify or extend it to address the particular conditions on your network. Appendix D includes techniques to troubleshoot poor streams that CQM surfaces.
The Networking Guide download now includes the list of Lync Server 2010 and an updated list of Lync Server 2013 KHIs to validate server health, a complete set of CQM queries, and a PowerShell script file to collect KHI data.”
