QoS over a backbone WAN

Whilst its fairly clear the best method for QoS on slow speed access links is LLQ, I can't find any CCO indications for the best method over the backbone. Specifically links ranging from 2mb to 155mb SDH. I would be particularly interested in any case studies and the results.

Re: QoS over a backbone WAN

Could you enlighten me on why you think LLQ is the best method for QoS on slow speed access links?

Thanks.

Re: QoS over a backbone WAN

We have a requirement to prioritise voice and grade remaining priority on a number of different types of traffic. I could also go through all the Cisco reasons, but its on CCO (i.e http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t7/pqcbwfq.htm) One of many write ups.
