Sorry, Vadim is wrong; but those who program small embeddes systems 
know a lot about this. Through _yes, the memory was the CORE - it had the
weight, the size, you could see every bit as a distinct hardware gift
-:). There was the CUBES of the MEMORY .


And I noted - sems momory should not be any problem today.
Just as CPU power. The network stability should be. And network resources.

Alex.

PS. Sorry for the offtopic in NANOG.

Aw, Tony, you're talking to a guy who made his name
programming discrete transistor computers with core
memory (i mean _real_ core memory, and real germanium
transistors :)

I bet he knows more than anyone else in this list about
squeezing bits :)

Cheers,

PS  Old-timers are entitled to being grumpy about how
    wasteful the modern computing is.  After all, how do you
    feel about operating systems which just have to have
    at least 30 Mb of RAM to be useful? :)

The growth itself do not cause the problems, but in conjunction with the
poor router implementation (which cause 60,000 routes to use 30 MB of the
RAM - that means 500 bytes for every prefix -:) and numerous memory leaks
in the router implementation cause the problem. If we look around, we'll
see existing computers (including embedded ones) have not CPU and memory
problems, and all problems we see with the routers are mainly caused by
the bad implemented text.

I, and the rest of the Internet community, would like to invite you to start a
router company and show us how it can be done with far less memory.

;-)

More seriously, you might take a look around and note that there are not a
great deal of difference in the amount of memory needed to support a prefix
across the various well-known implementations.  Which is not to say that we're
blameless, just that a lot of good people have worked hard and are all equally
incompetent at conserving memory while simultaneously producing a scalable,
stable, feature-rich implementation.

Tony
