Scottsdale, ARIZ. — Sales of asynchronous transfer mode (ATM)-based wide-area network (WAN) switches grew 6 percent in Q2 2000, reaching an all-time high of $922.4 million, according to Cahners In-Stat Group (http://www.instat.com/). The high-tech market research firm reports that Lucent, Nortel and Cisco remain market share leaders in this segment, with 27.3 percent, 21.9 percent and 21.1 percent, respectively.
ATM plays a critical role in service provider networks, where the rapid deployment of VoIP and xDSL is fueling the growth of ATM in the WAN. “It’s not about ‘IP vs. ATM’, but how IP and ATM work together,” says Laurie Gooding, Manager of WAN and Service Provider research for Cahners In-Stat Group. “Carriers like the flexibility of IP but they still want the QoS guarantees that ATM provides.”
In-Stat also found that in Q2 2000:
* A new class of purpose-built VoIP gateways supporting both IP and ATM-based traffic emerged, with sales of nearly $11 million. Sonus Networks, Unisphere and Nortel are market share leaders in this segment, with 41.4 percent, 17.9 percent and 11.9 percent, respectively.
* Sales of remote access concentrator-based VoIP gateways reached $180 million. Cisco, Lucent and 3Com lead in this segment, with 54 percent, 22.9 percent and 15.7 percent market shares, respectively.
