Hi All
I am struggling with a router throughput and hope someone can help
if i plug a cisco 880 router in to a 100MB WAN Ethernet circuit what throughput will i get? on cisco site it says 25mb/sec but if it is Ethernet shouldn't it be done in hardware and get the full 100mb/sec?
I know that a 1841 plugged in to a 40MB WAN circuit can match that speed but Cisco site say it only can do E1 speed
many thanks
Ben

An 880 is rated at 50 Kpps. For minimum size Ethernet packets, that translates to about 33 Mbps (simplex, i.e. half that for duplex). Performance capability should improve as packet size increases.
As to hardware, the actual receiving and sending of Ethernet frames is done on hardware, but the forwarding process between interfaces is done on software (on this kind of "software" based router).
PS:
BTW, the 1841 is rated at 75 Kpps.

Not knowing the performance specs for the d-link wireless home router, can't say whether the 880 would be a "downgrade".
Keep in mind, the performance specs I quoted are worst case. For something like actual traffic like IMIX, would expect much better throughput.
