Ipsilon Networks Inc, the company formed in Palo Alto, California to develop the Internet Protocol switch for routing IP traffic over Asynchronous Transfer Mode, has won an early ringing endorsement of its concept from NEC Corp, which is to market the switches in Japan at up to $200,000 each, and forecasts that annual sales in Japan will reach $365m by 2001. The two also plan to sell the systems jointly outside Japan, but don’t have concrete plans as yet, NEC said. Sales in Japan will start in November and the companies look to sell 400 in the first two years. Ipsilon will provide the Internet Protocol software for the systems, which will be based on NEC’s Asynchronous Mode hardware.
