NANOG, I realize that every SP handles marking and queueing/scheduling differently, but I am curious to see other provider's 'standard' config for QoS that is deployed on the JunOS platform. What config do apply to all your ingress interfaces for classification? How are your core link schedulers configured? What kind of remarking do you do (specifically on packets arriving on internet-facing interfaces)? If you have a converged network carrying both internet and carrier-eth/transport traffic, how do you handle guaranteeing bandwidth to the carrier eth services?
Upstream and peering facing ports get re-marked to DSCP 0 on ingress. Outbound traffic toward customers from any sources, as well as traffic handed off to upstreams and peers is re-marked to DSCP 0 prior to be pushed out, as we've noticed "bad things" can happen when other networks do special things with non-DSCP 0 values they may receive.
