It has begun ATM started with exaggerated enthusiasm, but many of those who once touted it as a cure for every network ill now pounce on its faults. Moreover, advocates of competing technologies have weighed in, armed with data that prove the superiority of whatever their embedded base is using. But reality should soon set in: The market--and our expectations--will shake out. Some of ATM's doldrums are just part of the backlash phase, where new technology always gets bashed--after it's been hyped and before it's gone mainstream. But customers are also confused by the many ATM standards and their relative states of completion. The pace of standards development and the ATM Forum's continual refining of specifications give users the message that ATM standards are not stable. While standards for LAN emulation (LANE), traffic management (TM), and private network node interface (PNNI) are complete, and the Signaling 4.0 spec is due to be completed in late April, controversy still surrounds LANE version 2, multiprotocol over ATM (MPOA), traffic management for available bit rate (ABR) and the User-to-Network Interface (UNI). The complaint that ATM standards aren't complete, while true, is irrelevant; there always will be a need for additional standards. And there's already a solid core of standards that enable the implementation of very capable ATM networks. While ATM's "To Do" list is still long, the Forum has checked off the top-priority tasks. Now that the engineers have finished the first version of specs needed to make ATM practical, it's up to the marketing gurus to convince customers that ATM is ready for prime time.
