The second big change is that the entire software architecture has been opened up. You can install your software, access any component of the switch, and even use common REST APIs to do so.

Each layer in the networking stack has traditionally been vertically integrated and restricted access for customers. The new Juniper QFX10000 software architecture removes these previous restrictions and makes it possible for users to freely modify many aspects of the software and hardware, as illustrated in Figure 2-1.
