I'm trying to figure out what router would be able to route fast enough to handle a 100Mb WAN circuit. I was reading the 3800 series router blurb which says "Built for performance, the Cisco 3800 Series routers deliver multiple concurrent services up to wire-speed T3/E3 rates". I don't know if that means it can handle the equivalent of multiple 45Mb circuits or a total of 45Mb.
I'm told this circuit will be delivered to us as standard 100Mb Ethernet using an RJ-45 connection. I was wondering if it would be dumb to just use a switch seeing as they seem to most of the features of a router these days.
