Hi All, I'm continuing to try and understand QoS a little better in relation to applying it to our MPLS VPN network but it seems the more I read about it the more I'm confused. Not to mention the lack of configuration examples out there. I understand that we can provide two QoS solutions for MPLS VPN customers. 1/ Guaranteed BW at ingress/egress (also known as the HOSE model). 2/ Full QOS deployment with varying class of service based on IPP and/or DSCP. In relation to solution 1, I'm not really clear about guaranteeing the bandwidth at the ingress/egress. Is the bandwidth guarantee in regards to the physical link connecting the CE to the PE? Or are we giving the customer a guarantee on the PE to P link (which would make more sense to me)? [ CE ] --- 2M/2M ---> [ PE ] ---> [ P ] Imagine if the customer had a 2M/2M SHDSL connection into the SP's MPLS network, are we able to for example guarantee a ICR of 256K and ECR of 512K??? And why would we do this when the customer would expect to be able to send/receive up to 2M because that's what they're paying for. My thinking is probably flawed, so if anybody could clear up my misconceptions about the hose model, that would be great! Thanks. Andy
