Research and Publications

My primary work responsibility is to architect, design and write code for the IONOS dataplane.  In my spare time (usually late nights or early mornings) i do all the research and standardization work in IETF. I am active in several IETF WGs and have published several drafts and RFCs. This page lists some of the documents that i have written:
