I am looking for a Rule of Thumb on failover for hosting, mostly tcp(webserver), some udp (audio/video streaming) stuff. My thought is that 5 seconds to failover when a network element(switch/router/load balancer/FW) fails is reasonable. How many seconds is reasonable for fail over in such a situation? Thanks in advance. __ James DeMong Network Design Specialist TELUS Advanced Communications Phone: (403) 503-3718 Email: James.DeMong@telus.com
