While this won't make a core router, it seems to offer something to consider, even learn from. One of my projects 25 years ago was to reduce the time to calculate the square root on a Seymour Cray machine by a factor of 20 to avoid spending $8 million on a second machine. The revised square root code performed in about the same time scale as the machine's hardware divide function. The clue came from one of the national laboratories and was published in Nuclear Science Abstracts. It took about 6 weeks to do the code and 18 months for the solution to be politically accepted. The original vendor does not always produce sacrosanct stuff. We just went through the process of acquiring our first significant router; one of our main concerns was a router which would allow school districts, libraries and hospitals to benefit from Texas HB2128, which offers distance insensitive T1s and DS3s and was co-authored by our telecomm lobbyist, W. Scott McCollough in Austin. I was somewhat dismayed at the memory limitations of current stuff compared to what I was hearing about the memory requirements. Jonah has more memory on his texas.net usenet news server than you can put on many core routers. Is there anyone working on alternative implementations of software which could possibly solve some of the problems using extant hardware? Will IP multicast help with the usenet stuff? Do we want to continue seeing cams at universities display the local tower while the institution doesn't meet RFC2050 guidelines with respect to utilization of their Class B while the rural areas can't get /19s to support diversity and redundancy? Does Congress need to pass "must carry" legislation similar to the "any willing provider" medical legislation? IMHO, it would be better that some old dogmas and implementations die and be replaced with efficient, robust code and a rather less limiting view of the future.

You'd retain most of the benefits of NAT. NAT is really well worth it in _some_ cases. We cut a 30 site WAN/LAN from one internet provider to another in 5 minutes. One of my clients had another problem with NAT. Seems that Cisco's NAT implementation translates DNS addresses in the payload when it is a plain query, and doesn't when it is a zone transfer. Meant that we couldn't have secondaries on the outside of the NAT. Also, their NAT implementation was absent for the 3600 in 11.2.4 and 11.2.5 (despite all documentation to the contrary). In typical cisco fashion, they lent us a 4700, so I'm not in any hurry to get it fixed. -- Allan Chong allan(a)alum.mit.edu "When I die, I want to go peacefully like my Grandfather did---in his sleep.

BIND 4.9 will start up in about twice the time, but then every 15 minutes it will appear to freeze solid while it stat()'s all those files. BIND 8.1 does it all incrementally. BIND 8.2 will have a clustered memory allocator which will make it start up in about 1/5th the time it takes now. But this is some months from now.
