If the Ipsilon approach is as described in the trade journals, this approach to integrating IP packet switching and ATM communications subnet cell switching ultimately may make no sense. >by the way, you don't need _bugs_ in datagram routing algorithms >to get loops, you just need transients in distance vector schemes.... True of course, but such transients are unrelated to ATM and can occur with any technology. With the VLAN architecture applied to ATM, the standard rules of TTL field deal with such transients as they do with other media. Joachim Martillo Inventor of the VLAN President Telford Tools, Inc.
