WE have an application similar to VOIP, does not tolerate delay. network:
A---1GB---cisco 3560----40MB MPLS NTU---4x separate offices
Goal is to shape outgoing traffic from A to NTU, not drop , like this:
if dest_ip is 1.1.1 shape to 10MB(each office), buffer excess burst, do not drop packets.
In summary, design QOS shape policy on 3560 to shape and buffer traffic to 10MB per office.
Its simple network, will provide diagrams and configs
