mentions 3 links between LBL and Arpanet:
- In 1974, the Lab’s CDC 6600 became the first online supercomputer when it was connected
to ARPANET, the Internet’s predecessor.
- In 1986, when the Internet was on the verge of collapse from congestion, a Berkeley Lab
researcher, Van Jacobson, co-developed the congestion control algorithms that allowed the
Internet to keep growing.
- In 1995, Jacobson and Steven McCanne developed MBone, the first successful software for
multiparty audio and video conferencing over the Internet.

Another clarification - LBL has never been part of UC Berkeley. It's
(always?) been a Department of Energy laboratory managed by the Univ.
of California. On the other hand, many people, due the close proximity
of LBL to UC Berkeley, have appointments at both places so it can
be hard to recognize which place somebody was working at when certain
research was done. For example, both Van Jacobson and Steve McCanne
had affiliations with LBL and UC Berkeley.

I really wonder how the CDC link worked. The channels were electrically strange, and
certainly not easily amenable to communicating with anything other than CDC controllers or
perhaps a serial line through one of the front ends.
I did hear of a proposal at NADC around 1977 to try to hook into telnet and ftp from a CDC
using some hack of the serial stuff. The idea didn’t impress me: it would have taken a
lot of hacking to get a kludge working. It always took a lot to make CDC hardware play
well with others.
