You know you can edit old posts, right?

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

As someone that posts from mobile a lot, frequently while driving /cough, I never have a problem with editing posts.

Cities are government agencies and often very out of date.

But should not be, that's not a ring.

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

IBM still had it in production well into the 2000s.
But that is a LAN ring. WAN ring was around longer.

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

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.
