First of all, three-layer or two-layer architecture are not invented by me, I just utilized them, and they are actually common topic today. There are lots of tools to support both of them. 11-layer architecture does not sound familiar to me ;-)

When you cutting something into layers, there is always a question of how and where to cut. Each layer of your 11 layers actually falls in one of my three layer. A good way to define layer boundaries has to be helpful and can be easily used to describe and understand the system and architecture.
