A process-oriented operating system, the Duplex Multiple Environment Real Time (DMERT) operating system, was designed for the 3B20D Processor and offers both real-time and time-shared operation, with emphasis on high availability. The design objectives and architecture of the DMERT operating system and an explanation of how the system performance is characterized are presented. A companion article describes in depth the DMERT operating system design.

TLDR
The key insight is that by making the basic network service selectable on a per user (or even per packet) basis, the need for formal standardization is eliminated and the deployment times, today constrained by capital funding limitations, are tremendously reduced.
