straw poll for multi-homed operators
- From: Joe Abley

[number 5 in a series of unscientific surveys]
If you currently multi-home between two or more providers using IPv4:
+ why do you do it? What are the high-level goals you are hoping to achieve?
Are you finding that you are achieving them?
+ how often does your traffic shift between transit providers due to
a failure of some kind triggering a re-homing?
+ how often do you manually shift traffic, and why? Just inbound traffic?
Or outbound too?
+ what impact does a manual or automatic shift in traffic between providers
have to your users? Do their TCP sessions break? Or do you think they
normally stay alive, maybe after a delay? What makes you think this?
+ what is *bad* about the way that multi-homing works in IPv4?
+ what is good about it?
Context is an attempt to nail down some requirements for a multi-homing
architecture in IPv6 (one that doesn't incorporate exciting up-and-to-the-
right state explosion in the DFZ).
I can summarise private replies if there is interest.
