I have an interesting scenario that I am working on putting together a solution for.
I have a metro Ethernet network with only a Gigabit backbone connection between 2 locations. I need to give a customer a 145Mbps circuit using a gige handoff on both ends, but do not want to give them the ability to use the full gig of course.
Now I know this is easily done with things like port channels and load balanced links, but the major factor in this situation is that there is a large amount of VoIP traffic being sent over the link(s).
I thought about doing some policy maps and traffic shaping down to 145mbps, but then I figured that the buffering of traffic when the customer is trying to exceed that 145mbps may cause issues with voip packets and latency.
Again, the issue with traditional load balancing with routing protocols is the possibility of packets arriving out of order etc.
I was looking toward a way to shape the traffic, as well as have all Voip traffic have priority and never be buffered, but if all traffic was voip, and the customer was trying to use say 150mpbs, then some would always be queue and then their would be latency?
Thanks for any response.
