Routers route based on dest address only. Are you somehow suggesting that an ISP can't be dual homed and use only one link if one goes down, since some of the addresses sent up the remaining pipe wouldn't have source addresses assigned by that upstream provider?

Its not senseless, you just don't understand how the internet works, apparently. I do this for a living, and you just yap. If you were able to "send back" the data on the "pipe it arrived on" then you would have uneven use of the "pipes". So one could be saturation the the other highly unused. Balancing the outgoing data would reduce the latency that occurs when a "pipe" is saturated. Its hard to explain calculus to some who can't add or subtract ted, so you should figure out how routing works before you try something this complicated. > > >then > >its likely more efficient to keep your pipes > >filled and send to "either" isp.

Since the internet is connectionless (back to school for you Ted), per packet balancing can utilize 2 outgoing pipes to different ISPs as well. Obviously since failover on dual-homed network works, you can send your packets to any ISP you want. Routers route based on destination address, as anyone who knows how routers work knows. You can even use per packet load balancing on 2 lines to the same ISP when the other end doesn't support it; using 2 pipes in one direction and only one in the other. You can be innovative when you actually understand how things work, Ted. > > Surprising you would drag up a Ciscoism as > your such a big fan of BSD-based routers. > > >or bit-balancing with a product like ETs for > >FreeBSD.

This is not just theory; its being done. You are wrong about every single thing you said in this thread.
