In part I of this post, we have seen how a layered architecture has transformed the communication network. What is so difficult about a layered architecture for the power network? Let’s again look first at its role in the communication network.
DARPA started a packet network in 1969 with four nodes at UCLA, UCSB, SRI (Stanford Research Institute), the University of Utah, that grew into today’s Internet. Early to mid 1990s was when the world at large discovered the Internet. The release of the Mosaic browser in 1993 by the National Center of Supercomputing Applications of the University of Illinois, Urbana-Champaign, has probably played the most visible role in triggering this transition. But 1990s was also the time when multiple technologies and infrastructures have come together to ready the Internet for prime time. What exactly was the role of layering?
