WAN tech

Do organisations still use stuff like ATM or Frame Relay? Is it largely fiber now as the main WAN tech in use?
 
Well I'm asking since the organisation I work for has a fiber WAN, and just wanted to know how common it is.
 
ATM and frame relay are going away. Frame in particular is pretty dead now, hard to get switches that support it anymore. ATM is a horrible protocol suite, so good riddance.

Depending on application, MPLS, Metro Ethernet, and various packet over SONET (POS or Ethernet emulation) technologies are what's common nowadays for new circuits.
 
I keep wondering if frame-relay is still popular in developing parts of the world. I haven't seen any evidence either way, but that doesn't stop me from wondering. Anybody heard anything?

Fiber is just how it's delivered. It could be any NUMBER of WAN technologies using the fiber.

ATM
SONET
Metro-E
MPLS

For the business to have a "true" fiber WAN they would own the fiber and their own optical switches to run the SONET. That is normally cost prohibative so they pay a provider for a WAN service like I listed.

We run one. But we are a provider. That being said - in the "developing" part of the world, Metro-E and MPLS are what is hot. We work in the Caribbean and into Central and northern South America, places people perceive as likely to be satellite only.

Believe it or not - you can get a 100/10 cable with triple play anywhere on Jamaica for less than I pay for 12/2 to Comcrap.
 
I work for a large company and we have pretty much everything

some sites still running 56k
one site still running ATM
tokenring was finally turned down last year

But we also have some nice new stuff

Lots of Gige.

Dual oc-192 ring from one provider and OC-48 ring from another.

Private fiber ring around an office park(~2 miles and over 500 strands).
