Oops, sorry. As you might know, with Ethernet, the cost of a 100Mbps OE is about $200, pair of which will be used for each subscriber. (I'm overestimating the cost of OE by not assuming a dedicated hardware) So, a 100Mbps NAT box should costs $100 or, maybe, $200. Actually, 100Mbps case is not very realistic, because of the management cost. A 1Gbps NAT box may be shared by 100 subscribers and may cost $10000 or, maybe, $20000. > > I was asked by ISPs which are beginning to offer 100Mbps Ethernet service > > to subscribers. > > They probably have a little cash then...

Hmmmm, $109,000 seems to be too expensive. > Anyhow they claim lots of sessions: Each subscriber won't need so many sessions. Masataka Ohta
