 Did I understand him correctly saying there are still ring networks used by metropolitan areas?

 @mary said in Network Topologies - CompTIA Network+ N10-007 Prof. Messer: Did I understand him correctly saying there are still ring networks used by metropolitan areas? Resilient fiber networks frequently have two fibers - one going in each direction. It's often called a fiber ring.

 @Dashrender yes, sometimes it doesn't work on my phone

 The last true ring network I worked with was token ring. Went away completely mid 90s, and good riddance.

 I always create 2 diagrams for Network Topologies; - Physical Connections
- Logical Connections

Resilient fiber networks frequently have two fibers - one going in each direction. It's often called a fiber ring. But should not be, that's not a ring. Yes, it is. Looks like this for example:  Network topology is a ring. But it's still good ol' ethernet. I believe each blue line is a bidirectional link. So that each switch has two incoming links and two outgoing links. This type of topology is very common for a backbone where you have long distances. While a full mesh network is more resilient it requires a lot more fiber.
