There are a few out there. The entire Excelan line (now being sold by Federal Technologies), Interlan, and probably a couple more. > And would they end up faster? Typically this is a slower solution than host based protocols. Why? Because in order to keep the price down, the on board processor, the one that runs your TCP/IP stack, is slow. Typically a 6-12 Mhz 80186. This is a lot slower than a 25+ Mhz 80486/R3000/SPARC/RS6000/PA-RISC/... when it comes to fiddling bits and computing a checksum! In general, there is no reason why this architecture cannot give you equal or better performance that a host-based scheme, but you have to put a *real* cpu on the network board. If you find one, expect to pay big bucks. --- Larry Philps, SCO Canada, Inc. Postman: 130 Bloor St. West, 10th floor, Toronto, Ontario.
