We have an ISDN line, a T1, and a DSL connection. I do not need to worry about the particulars of each connection, because I actually have an ethernet drop for each of them - someone else does the routing/csu-dsu/etc. - I just get a usable ethernet drop that supports DHCP (a distinct DHCP service on each port - they aren't related). What I would like to do is build a PC with three network cards in it, connect each card to each of those three network drops, and use 10% of the total bandwidth of each connection - somehow turning that into one single network connection that that PC would use. BUT I do not want some kind of round-robin scheme wherein TCP session X uses the fraction of the ISDN, and TCP session Y uses the fraction of the T1, etc. - I want the end result to be one single connection that behaves just like any other single connection. Is this possible ? Is netgraph one2many the correct mechanism to be looking at ? Basically I want a connection that, at the end, presents itself to the system as one single connection with one single IP, and gives effective bandwidth of (percentage-ISDN) + (percentage-T1) + (percentage-DSL). Thanks. __________________________________ Do you Yahoo!? All your favorites on one personal page – Try My Yahoo! http://my.yahoo.com
