Hi,
I have a question about the ring network topology and redundancy. The network will be on a fiber optic media. I've been doing some reading and found out about switches that use a spanning tree protocol to help find a new path if a link was ever broken. My question is, when it comes to the physical construction (laying out the fibre cable) are you basically using two separate fiber cables (16 or whatever strands each cable) to build two rings (inner ring and outer ring) and if there is a break in one ring the spanning tree protocol will reroute to the other ring or use the other ring to heal the break? Of course this will require double the amount of fiber cable.
Or
Do you just lay one cable in a ring topology and if there's a break the rapid spanning tree routes the traffic to go the other direction therefore not needing the other ring? Can a ring topology transmit in both directions?
Also i'm just strictly talking about one break in the ring...if there are multiple breaks, its assumed the station that between the broken link can't be communicated to.
I'm designing a network architecture (its my first network design) where i'd like communications from two buildings (about 15 kms apart) but i'm picking up about 15 other stations in between, but i'd also like to keep costs down while keeping the network as reliable as possible.
