Currently we are experiencing latency issues with Sprint's MPLS network. When these spikes happen (3 in the last 3 months) it becomes service affecting for us and with a backup network in place, traffic will only fail over if the MPLS circuit goes down hard. I've been searching for something, some monitoring application that could send a remote command to the routers interface to shut so that traffic can fail over in these occurrences, but I'm having no luck. Is there any thing out there that can do this? We need something that can monitor latency and trigger and action on the router when latency hits a certain threshold for a X amount of seconds. This is something that we'll be very valuable once we begin running voice on these lines.
