I think NSDI is a top conference. Perhaps if you regard SIGCOMM as the flagship networking conference, NSDI should only be A and not A*, but I would have given it A*. Certainly it is not a B.

Agree with Douglis. NSDI is well regarded as a top-tier conference among networking people in CS. Since this website ranks INFOCOM and CoNEXT as A conferences, I think NSDI should be given A* in accordance with the relative reputation in academia.

NSDI is definitely an A* conference. Networking and Networked Systems Researchers submit to either NSDI or SIGCOMM depending on the dates their work is completed and rarely they make a noticeable rank distinction between the two. It is also quite common for high quality papers rejected in NSDI or SIGCOMM to be resubmitted with improvements to SIGCOMM or NSDI. Also, it should be named USENIX Networked Systems Design and Implementation.

SIGCOMM and NSDI are by far the best conferences in networking, so they should both be CORE A*. The top CS "elite" ranking includes only these two conferences for computer networks: http://csrankings.org/#/index?all.

This is without any doubt an A or A* conference, certainly not a B. Edit following the 2020 update: I cannot understand the decision to consider this conference as a 'regional conference'. CORE already ranks other USENIX conferences held in the USA or Canada (e.g. ATC, Security, OSDI, ...) as A or A* and does not seem to consider their location as an issue.

It's rather weird not ranking NSDI as A++ due to the USA being the country of holding the conference.
