Smart
I do think this is a smart move; Juniper's only going to be able to move so many 80Tbps routers, and will only want to "undersell" them so much (i.e. sell the 80Tbps router license-locked to 20 or 40Tbps or whatever.) Furthermore, 100mbps or a few 100mbps doesn't need specialized hardware to handle the load any more, but one may still want the specialized software functionality.
