Router ISR 4351 throughput speed

[joaobor]

Hello,

I have question on Cisco ISR 4351/K9 without any license can reach 200Mbps bidirectional (download and upload at same time or only 100Mbps each)?

Best regards

So as I can understand the Aggregate throughput for an 4351 200Mbps is not bidirectional I can only get for example 100Mbps down and up at same time right?

Yes, correct, but also keep in mind, since it's an aggregate for the whole router, if down was, at that moment using only 75 Mbps, up could, at that moment, use up to 125 Mbps.

Oh, and to be clear, the up/down would normally be on different links.  Possibly it's easier to think of the bandwidth limit looks at all the traffic crossing the router's "backplane".
