10Mbps switches with 100Mbps FDX uplink ports are rather cheap these days. Just use those and fergit about it; your backbone is then 100Mbps FDX, and the drops are either switched 10 or 100Mbps (depending on where you drop from). We have been smurfed at *sustained* rates in excess of 70Mbps (two full-bore DS3s worth - peaks right up at 44.7 X 2) and haven't managed to saturate this back-office network fabric :-) Want a second free tip?
