Subject: Unequal balancing on bonds with links down
Date: Fri, 01 Feb 2013 16:20:36 +0100 [thread overview]
Message-ID: <ee92daba1b8af8e3e2b743bcb0c4d25f@luffy.cx> (raw)
Hi!
When a bond has one of its members down, the balancing becomes unequal.
For example, a four-member bond with the first member down, all the
traffic that should have been sent to this first member is sent to the
next one. This may be a lot of additional traffic for one interface.
This applies for both balance-xor and balance-rr. For balance-xor, the
hash could be computed modulo the number of active interfaces. For
balance-rr, inactive interfaces could be skipped. Is there some reason
that selection of TX interface is not done this way? If there is none, I
may come with a patch for this.
