Re: Regarding global BGP community values
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, --vadim 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? :) From: Tony Li <tony1@home.net> "Alex P. Rudnev" wrote:

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.

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.
