I think that the origin of the system is pre-Diocletianic.
The "classical" limes in Syria and Tripolitana/Cyrenaica was already an open system. Many positions were occupied to control the nomads of the desert and steppe. This already involved some depth.
In the Gallic Empire, the system of a double line can be dated to the Gallic Empire ([url:3l1lxfla]http://www.livius.org/ga-gh/germania/inferior10.html[/url], scroll down a bit). This is based on Danny Lamarcq & Marc Rogge, De taalgrens (1996 Leuven). I am unaware of English publications on the same subject.
