Fuzzball router

Fuzzball routers were the first modern routers on the Internet.[1] They were DEC LSI-11 computers loaded with the Fuzzball software written by David L. Mills (of the University of Delaware).[2][3] The name "Fuzzball" was the colloquialism for Mills' routing software. Six Fuzzball routers provided the routing backbone of the first 56 kbit/s NSFnet,[4][5] allowing the testing of many of the Internet's first protocols.[6] It allowed the development of the first TCP/IP routing protocols,[7] and the Network Time Protocol.[8] They were the first routers to implement key refinements to TCP/IP like variable-length subnet masks.[9]
