Do you really need something faster than one of the spanning tree variants?

The topology at Montana Internet is to have a layer 3 switch at each site and a big flat rapid spanning tree ring for all of the OSPF speaking layer 3 switches (Aka routers) to talk on. If I yank a ring cable, I lose about a second on two is all.

    Looking to add Ethernet ring protection switching into our
    network. I've attached a PDF demonstrating the topology of the

simply because it's ITU standards based and not vendor specific. Other options include Brocade MRP, Moxa Turbo Chain, etc. Any
    shared wisdom would be greatly appreciate before we get ourselves
