Funny I thought a "switch" was a multiport bridge... uses the MAC headers to flood. ahh makes me long for the days of Kalpana. Scott C. McGrath On Fri, 31 Oct 2003, Stephen Sprunk wrote:
Thus spake "Daniel Golding" <dgolding () burtongroup com>Hmm. Don't you just love it when folks say things like "Layer 3 Switchesarebetter than routers". Its very illuminating as to clue level. I suppose what they were trying to say, is that products that weredesignedas switches, but are now running routing code, are superior to productsthatwere designed as routers, and are running routing code. Of course, this is demonstrably false. "Layer 3 Switch" is like "Tier 1 ISP" - meaningless marketing drivel, divorced from any previous technical meaning.I've always stated that "switch" is a marketing term meaning "fast". Thus a "L2 switch" is a "fast bridge" and a "L3 switch" is a "fast router". In this light, the Yankee Group is just now catching on to something we all knew a decade ago -- slow (i.e. software) routers are dead. There's a more interesting level to the discussion if you look at what carriers are interested in for their backbone hardware today; while I'm obviously biased based on my employer, I've seen a lot more emphasis on $20k-per-10GE-port "L3 switches" than $200k-per-10GE-port "core routers" in the current economic climate.
