Bandwidth management

Hi guys

I thought you might be able to help me with some advice. I have a link between two locations and 3 IPSEC Vpn tunnels on it. I would like to share the bandwidth between those tunnels (lets say tunnel group1 gets 20Mb, tunnel group 2 is allowed only 5 Mb and the rest is for the third tunnel). I know I could use QoS policies. But from my understanding they kick in only when congestion occurs. Is there way to limit the bandwidth used by certain types traffic not only in times of congestion?

Many thanks

Elena

Re: Bandwidth management

Elena, have you come across qos and rate limiting , there is nothing I have read referencing rate limiting traffic kicking in only when when congestion occurs.

Re: Bandwidth management

Besides Jorge's mention of rate limiting (or policing), shaping is another method to restrict bandwidth utilization.

What's not clear, to me, is why 3 tunnels between the same two locations. Depending on platform, often better is one tunnel between locations that you manage bandwidth usage by different types of traffic.

Re: Bandwidth management

Hi

I didn't actually mean 3 separate tunnels (I don't think you can implement separate tunnels between two same locations), but separate flows of traffic on the same tunnel.

I used policing and so far we didn't hit any issues.
