Cisco 2911-Sec Max Bandwidth Tool

[tmassei01]

I'm looking for a tool that can find max avail bandwidth between two Cisco router each connected to the internet with VPN tunnels to each other. Any suggestions?

[Joseph W. Doherty]

For a manual test, or for some on-going testing?

Paid or free?

Platform(s)?

Personally, I've found PCATTCP (windows) UDP generation, good for stress testing a path's bandwidth capacity.  (I've found most Windows laptops able to blast out UDP in excess of 100 Mbps.  I haven't a tool to stress gig paths.)

PS:

BTW, Cisco IPSLA might be able to check bandwidth across a VPN tunnel.  (I recall the latest DMVPN even supports dynamic traffic shaping based on IPSLA derived available bandwidth.)
