Let's say I live in a dorm room, or a large condo building.
And let's say that everyone has the same ISP, and everyone is getting 3 mbps
down and 512 kbps up, and there is no possibility of a better connection.
And finally, let's say that everyone is running wide open wifi access points.
Would it be possible to equip a computer with four (or more) wireless ethernet
cards, jump on four open APs simultaneously, and bond them all together with
netgraph to get a 12 mbps down and 2 mbps up connection ?
The two main conceptual questions I have about this are:
- do I need a back end somewhere (a collocated server) to tie all four
connections back together into one again ? If I round-robin through the cards
for each network request that would not _truly_ give me a bonded connection,
and I wouldn't often get the full bonded bandwidth (unless I was doing lots of
tiny, concurrent network transfers). It would seem that if I wanted to truly
bond the connections into one, I would need them all to talk to some central
server that would represent it to the world as a single IP ...
- I have read that bonding wireless cards with netgraph is not as easy as
bonding normal ethernet cards, because you need to arbitrarily assign and
re-assign MAC addresses over and over on the fly, and the firmwares of many
wireless cards do not allow one to do this ... I believe I saw a posting from a
few years back that indicated Lucent cards (for instance) could not do this ...
Comments ? The idea is to bond things into one, single, usable connection that
could provide multiple connections worth of bandwidth for single-threaded
network transactions (like downloading a single file from an ftp server).
Perhaps there is a better tool to do this with than netgraph ?
