I work on large Telepresence networks where packets can't be dropped. There is a great deal of Ethernet being used and the different routing platforms have different capabilities, and Ethernet doesn't communicate from PE to CE, so it isn't like ATM UNI and Frame Relay UNI where both platforms hopefully followed the standard for congestion management and QoS.
Has anyone seen any white papers or good discussions on how to optimize your QoS policies over Ethernet, particularly the shape average command's bc on your CE router when your carrier's PE router has a policer that has a specifc known bc?
