Hi,
Hi,
I need the model ISR router for use with two 100MB internet links with load balancing and failover,
at first I'm thinking about the 1900 series, and would use the SCAN SAFE (CWS) to filter web content,
This equipment would support two links 100mb each? Which model would be suitable for this?

Dual 100 Mbps on a 1900? You might want to review the attachment.

Hi
i have Considered the last graphic "WAN Circuit Speed (Mbps)" is correct?
In the document, the Cisco 1900 have the capacity for 15Mbps, but i need use two ISPs with 100Mbps each one .. then i use the 3945, 3925E for this case?
Traffic will only output, using internet access ..

WAN bandwidth means the router can handle that link running full duplex.
If your 100 Mbps is asymetrical (e.g. ADSL or cable modems) or there's a logical bandwidth cap, you can size for that (although don't forget to allow for bandwidth upgrades, if you plan any within a couple of years).
Also, the Cisco recommendations are conservative and assume the link running flat out. Often you can size smaller, i.e. for your usual bandwidth consumption and a little more.

If you have two ISPs, then better of using two 3945s. You might want to consider running fibre to the ISP.
It's about scalability and using the both of the link for either redundancy or load-balancing.
thx,
