Re: Microwave...

ESnet is running a dual OC-3 microwave link to provide connectivity to
NERSC, the National Energy Research Scientific Computing Center in
downtown Oakland, CA from Berkeley Lab. We had some early equipment
failures that kept the bandwidth to a single OC-3 for a while, but
it's been operating quite well for several months, now.

While we have an OC-48 fiber on order, it could not be installed
before NERSC moved from Berkeley Lab to Oakland due to permit issues
and having a super-computer center with no external connections seemed
like a bad idea. Microwave was the obvious option as we have a clear
line of sight of only about 5 miles.

OC-6 is less bandwidth than we would like, but the users are at least
getting passable access.
