Hi Oscar, ATM isn't really a LAN technology. It's actually a multi-purpose technology that was designed to effectively carry multiple types of traffic (such as voice, video and data) in a variety of environments. In fact, we no longer recommend ATM for LAN environments as Gigabit Ethernet is cheaper and simpler for backbone use, and prioritization schemes such as 802.1p can provide sufficient QoS for most applications (though there are a few rare applications such as telemedicine that may require ATM's guaranteed quality of service support). ATM is currently the predominant technology in wide-area networks, though over the next few years I believe that MPLS will increasingly be used to replace ATM's control-plane, which will relegate ATM to simply a transport mechanism at Layer 2.

Since ATM is a LAN technology, I would like to know the maximum distance of ATM network. I would like to know if it can be implemented on a very wide campus network as the backbone. If ATM is used in a MAN network backbone, what type of connections are used between the differrent regions in the MAN? Is fiber used for connecting the different regions or is it a Frame Realy, ISDN type of connection? Thanks for any info. -- Oscar Rau [EMAIL PROTECTED] ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
