Looking for a solution to solve a problem that I've had for a few years, but is now getting serious enough to do something about. We have about 50 WAN connected sites over an AT&T ASE metro ethernet service. Our datacenter has a 40G connection to the network. Our other sites have either 10G, 2G, or 500Mb/s connections. The problem is that the datacenter side sends data faster to the sites faster than the site's CIR with AT&T. This causes AT&T to drop everything that exceeds their CIR which causes massive performance issues to the point where VOIP phones and most other WAN services like Internet and email pretty much stop working. I need a solution that will slow down/buffer traffic that exceeds the site CIR before it hits AT&T and they drop it. Just doing QoS policing from our side doesn't help. It just moves the problem from AT&T to us and the end result is the same.
AT&T will not shape the traffic for us. As per our contract, we are required to manage our own traffic in a way that keeps it under the contracted CIRs. This would be easy if all our sites were connected back to our datacenter on separate ports. Almost all even midrange network gear can do traffic shaping on individual ports. The problem is that AT&T will only give us one port in our datacenter. It's a 100G handoff that has a 40G CIR. We have all our site traffic coming over routes on individual VLANs, but most midrange equipment can't apply QoS traffic shaping to VLANs or subinterfaces. I know I can do what needs to be done on a big Palo Alto solution as I've tested it on a small level with some of the gear we have. I just don't have anything big enough and can't get anything big enough for probably a year because of the way we are funded.
I just put in a Fiberstore S8050 100G switch to bring in the connection to AT&T. I've been trying to get some QoS stuff working on it, but haven't been able to get it to work on the separate VLANs I have set up. FS switches are based on Arista EOS, which is Cisco-like, but not exactly the same. If there are any Arista QoS pros out there that can led any advice it would be appreciated. I'll be happy to send over our current config for review.
Anyone ever have to deal with this? Any specific hardware you can recommend that 1. has enough traffic shaping buffering queues to handle 40+ sites and 2. will allow the application of traffic shaping (not just policing) policies to VLANS or subinterfaces?
