How does Cisco routers throttle traffic?
Posted on 2009-04-23
We are trying to solve a problem with oversaturation of our network WAN connections.
Here's our situation:
5 sites with Cisco 2911 routers connecting to AT&T's MPLS network - T1 connections.
1 site wih Cisco 3845 router connecting to same AT&T MPLS network - DS3 connection.
The DS3 was an upgrade from a burstable 3mb pipe.
Normal business network traffic: Exchange, web, file transfers, etc coming over the wire.
Our support is suggesting that we are having problems due to the disparity between our speeds, and that we are pushing more traffic than the T1s can handle.
This doesn't make sense to me. If this was the case, then every site in the world would have to be the same speed.
Please explain how traffic is regulated or throttled across the internet, especially an MPLS network.
