Frame relay won in the WAN over ATM, which proved too expensive despite its good points, such as five levels of QoS. Now MPLS is pushing aside both. The debate about frame relay vs. ATM as WAN ...

Erin Dunne, director of research at Vertical Systems Group, says companies migrating from frame relay and ATM are moving to Ethernet faster than those using private lines, including T-1s and higher.

Out with the old (frame relay, ATM and subscriber lines) and in with the new (e.g., Ethernet or IP MPLS VPN services). That's the latest trend in enterprise networking, according to market watcher ...

In 1992, frame relay was portrayed as an interim technology that would be replaced by Switched Multimegabit Data Service. In 1995, industry insiders predicted frame relay would be devoured by ATM.

The ATM bandwagon isn't free-wheeling through Europe as powerfully as expected. According to a new study by Total Research European, network managers perceive ATM to be the leading-edge technology of ...
