I'm having a discussion with a small network in a part of the world where bandwidth is scarce and multiple DSL lines are often used for upstream links. The topic is policy-based routing, which is being described as "load balancing" where end-user traffic is assigned to a line according to source address. In my opinion the main problems with this are: - It's brittle, when a line fails, traffic doesn't re-route - None of the usual debugging tools work properly - Adding a new user is complicated because it has to be done in (at least) two places But I'm having a distinct lack of success locating rants and diatribes or even well-reasoned articles supporting this opinion. Am I out to lunch?
No, but what better solution do we have to offer them? There are dynamic load distribution features and products (think Cisco PfR, for example), but those are routinely lambasted as well. - -- ========= bep -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlJYgsoACgkQE1XcgMgrtyaHOgCfaS58WFFKaXfY87FddXZu4SGb b60AoPMY73ZtENIW4akBZbUMN0H9euY2 =XSi6 -----END PGP SIGNATURE-----
