In previous life working with L3 MPLS VPN with deliveries far exceeding on-net size we bought access from partners and had QoS contracts in place, which were tested and enforced and they worked after some ironing during field trials. Usually contract was bidirectional, with partner also using our network for extending reach of their network, so both had incentive to offer working QoS with network-edge translation of marking. -- ++ytti
