[nsp] 5 9's infrastructure, stateful failover

[Cheung, Rick]

	Good afternoon, folks. We're tasked to 5 9's uptime as a recent
challenge, and we're doing an audit on our infrastructure to see if we can
deliver. 

	What technologies would lead us closest to 5 9's for uptime, in a
LAN and WAN environment? (HSRP, Rapid STP, VRRP, redundant circuits)

	Ideally, the convergence would be as short as a stateful failover on
the PIX. 



Thanks,
Rick Cheung
