two (parallel) Ethernet cables between two hosts?
Is it possible to have two Ethernet (cat5) cables between two PCs and
double the bandwidth between the two (assuming they were crossover cables)? As a variant of that, would it be possible to have two normal Ethernet cables going from one PC to a switch and two more cables from that switch to a second PC, and double the bandwidth between the two that way? I don't know the right terminology. Is that what is called multipath? Anyway, if it is possible, how is it set up? Does something go into the Ethernet card configuration files to say they are special? Does it require some special feature/driver in the kernel? Etc. Thanks. |

I've done this with windows but never tried it in linux (where I work uses windows and I don't have the need for it). What I have used is Fast Ether-Channel or FEC. I think it requires a switch. It bonds the 2 NICs together and at 100 full duplex this gives 200 megs each way so a maximum of 400mb/s. I'll have to look into this some more and see if I can find anything about this in linux or about doing it directly with crossovers instead of having to configure the switch.
