Hi there, How to complete 25M ATM by 155M? (without speed!) What lack in 25M by now? (no matter which vendor's product) Or, what network application can not run on 25M ATM? And, what lack in 25M intergraded with 155M in IBM? They can support 25M interface to desktop with low cost, how to beat them? A very urgently answer needed! eric [Posted by WWW Notes gateway]

| 944.1 | How about talking about Fast Ethernet? | TWICK::PETTENGILL | mulp | Fri May 23 1997 02:51 | 17 |
Unfortunately we don't have a super Fast Ethernet story on the hub end, but we are doing pretty well from the chip standpoint and will eventually get things together with the hubs. So, I would ask, why are you willing to limit yourself to only 25mb/s when Ethernet is now standard at 100 mb/s. Let's see, if you did 4 DE500s to an Etherworks 8TX and this into one port of the VNswitchEX, you give each end system at least 25mb/s and more likely they will get 100mb/s. Then VNbus to a VNswitchEA and you are now ATM. Since there are two 100TX ports on the EX, it looks like 8 x 25 mb/s is two 100TX hubs, 1 EX, 1 hub900, 1 EA, 1 port on an ATM switch. That might be a bit too simplistic, but while this solution isn't full duplex, when there is no contention, an end system will be able to operate at 2-3 times the speed of 25 mb/s. | |||||
| 944.2 | right ! | LEMAN::CHEVAUX | Patrick Chevaux @GEO, DTN 821-4150 | Fri May 23 1997 09:28 | 2 |
Certainly the right counter-approach. Now, IBM, Madge, etc ... will
win on price vs the VNswitch.
