The Fuzzball was a PDP-11 operating system by David Mills. Although it was originally designed as an investigative tool and prototyping work-bench, it saw extensive use in early Internet work as a backbone router for the NSFNET.
Operating System
This operating system was built atop of RT-11, where RT-11 would boot, then directly jump into a virtual Fuzzball machine. If you needed to change something on the underlying host, you needed to reboot the machine.
Deployment within NSFNET
Deployment as NTP Servers
Examples of routers
- DCN1: lsi-11/23 (256k), kwv11, rx02, rl02, dlv11, interlan ether
- DCN2: lsi-11/73 (256k), kwv11, rx02, rl02, dlv11, interlan ether
- DCN4: lsi-11/73 (2048k), rx02, mscp, dlv11, dmv11
- DCN6: lsi-11/73 (2048k), rx02, mscp, dlv11, dmv11, etc
- udel7: lsi-11/23 (256k), rx02, rl02, dlv11
- wwvb.isi.edu: lsi-11/73 (256k), kwv11, rx02, rl02, dlv11, interlan ether
- backfuzz.pa.dec.com: lsi-11/23 (512k), kwv11, mscp, dlv11, deqna ether
- timer.nta.no: lsi-11/23 (256k), kwv11, rx02, rl02, dlv11, interlan ether
