Although Webex Control Hub provides great analytics for monitoring the utilization of Video Mesh Nodes, for planning purposes, a sizing tool will be very helpful.
The Video Mesh Node deployment Guide includes a table for CMS1000 and NM410V, for 720p and 1080p calls. However, this has limited usefulness as customers' scenarios are likely to be a mix of calls that only connect with audio and calls that that connect with audio and video.
With a sizing tool (like the old DSP calculator), customers can enter their anticipated use models and come up with a capacity that would serve them well. It would be a great way to do "What if" scenarios for customers.
