Is ATM still the latest and greatest Internet Backbone technology?

I've got a Marconi ASX-1000 in my network and was just wondering how prevalent ATM is in the public sector. Anybody who works with WANs feel free to chime in. 🙂

Uhhh, OC-3 is a physical medium, which is layer 1.

ATM is a layer2 (sometimes layer 3 ) protocol, you can run ATM over OC-3s.
 
ATM sure is prevelent in the US still, and like 95% of telmex (huge ISP dropped tons of $$$ into alcatel ATM core networking) network is all ATM other countries are trying to shift but then again I work mainly in the Carribean & Latin American sector.
 
Given the choice between ATM and stapling ethernet to the telephone pole myself, I'm going to be climbing some telephone poles

Not really a WAN guru eh?

ATM is the shiznit. Unfortunately, its not used much. I spent nearly 5 years supporting ATM on WAN's for about any company you care to mention both public and private.

Personally, I think its the best protocol out there. That said, its not used very much at all.

And I know all about those Marconi's. Do you run IMA on them?
 
For WAN, ATM is widely used; especially in DoD and government. Second most widely used would be IDNX/Promina.

For LAN, it ethernet slowly being replaced by Gig-E; again speaking from the DoD and government perspective.

The .gov uses ATM a whole hell of a lot. The JCN NOC, DOE, DHS, INS, FFA etc etc

Ahhh, the stories I could tell you. :laugh:

Just straight IP over OC3?

Yes. Just like I answered in networking.

Packet over Sonet. ATM is a dinosaur and isn't used much except for telphone and legacy TDM networks.

Essentially it is just IP over sonet.
 
I love how wildly different the answers in this thread are.

You see one post saying "ATM is awesome, but not widely used", the next post is "ATM is used all over the place" and then there are posts about how it's crazy old and terrible, or it's solid and great, hahahaha.

NERD FIGHT!!!

Well, percentage wise I dont think many companies use ATM. Its not something you generally find in small business's.
As for ATM being a bad protocol, that depends. I cant see anyone really saying its a bad protocol though, its a very good one. Every one has its advantages and disadvantages though.
 
The best analogy I've heard is that ATM is to networking as the Beta Max was to the video tape solution. It's better but wasn't as widely used so it's going away. The IP guys essentially beat up the ATM guys.

It didn't work very well for packet networks which is where we were going anyway. Especially since MPLS does it better anyway.

In the enterprise arena, it never took off and is totally dead. OPs switch is best used as a boat anchor or target practice.

Haha, that about sums it up.
The IP guys DID in fact beat up us ATM guys. 😱

Oh well, thats why I switched from ATM to VOIP. Kinda miss ATM, but gotta go where the money and future is. They told us up front, ATM will be dead by 08. Thats the plan, I dont see it working out like that though. IP is gonna have some big hurdles to jump to replace seamlessly replace ATM.
