Gee..., why didn't anyone else think of that? Cisco, are you listening? You need to make a GSR that does BGP updates faster, ok? While you're at it, you need to write bug-free software and build routers that never fail, ok?
C'mon. I'm obviously not suggesting it is as easy as "ask and ye shall receive". My point here is that demand drives the market, and if it becomes clear that routers with faster BGP implementations are what is needed, that is just what the vendors will (eventually, at least) develope.
you're forgetting (or not admitting here) that a corporation's primary motivators are profit and shareholder value. a vendor will surely develop anything that gains them significant market share, or significant increase in profits, or significant increase in revenues. driven by demand alone, a market is not. "routers with faster bgp implemetations are what is needed" is what we say, but the question a vendor asks is "does it increase my profit margin, revenues, or market position?". what we "want" is mostly irrelevant. -b
