Valid point. An out-of-band network tap is definitely a pretty insider-y term to the networking community. What it means is that there's a device sitting in a company's datacenter that can receive a copy of all the traffic flowing through that network without impacting the performance of said network. Some performance management tools will use up some of the bandwidth of a network to be able to perform their duties. An out-of-band tap offers a way to get visibility into what's happening in your network so you can monitor performance without sapping bandwidth.
