GridStat is a new kind of publish-subscribe data delivery service designed specifically, from the bottom up, for delivering real-time operational data of the electric power grid. We overview the data delivery needs of the electric power grid and analyze why neither the Internet and its existing technologies nor existing publish-subscribe products and research meet these needs. We introduce periodically updated variable and periodic update flow abstractions and describe how GridStat, as periodic update flow middleware implements these abstractions with very low latency and high availability.

David E. Bakken is an associate professor of computer science in the School of Electrical Engineering and Computer Science (EECS) at Washington State University (WSU). His research interests include middleware, distributed computing systems, fault tolerance, and quality of service frameworks. He has been working in GridStat for 10 years now, and has greatly influenced the emerging NASPInet for the power grid. Prior to joining WSU, he was a scientist at BBN Technologies in Cambridge, which built the first internet in 1969, where he was an original co-inventor of the Quality Objects (QuO) framework. He has consulted for Amazon.com, Network Associates Labs, and others, and he has also worked as a software developer for Boeing.
