Switches like this and the force10 2410 and the like are cut through so do sub micro second versus a 'regular' store and forward switch ------Original Message------ From: Holmes,David A To: Deric Kwok To: nanog () nanog org Subject: RE: switch speed question Sent: Feb 24, 2009 1:03 PM Arista claims to have the fastest 1/10 Gig 24 and 48 port 1RU switch, with a backplane capacity guaranteeing 10 Gig full duplex line rate per port. Cisco's CEF is local only and functions to download the arp cache and routing table into ASICs for hardware switching; but look at Cisco's NSF/SSO for cases where adjacent devices are all defined in the same packet forwarding state machine. -----Original Message----- From: Deric Kwok [mailto:deric.kwok2000 () gmail com] Sent: Monday, February 23, 2009 5:08 PM To: nanog () nanog org Subject: switch speed question Hi Can you share your experience what is fastest Gig switch?
