I'm curious about the interest in a hash code based algorithm that would
redirect packets to a real server based on source IP. So it would
compute a function given the IP and mod that by the number of real
servers. If a real server went down then it could do another hash
function for the machine that went down. So let's say machine a5 out of
real servers a1...a16 wend down. If the hash function maps someone to
a5, it would then compute a hash based on 15 machines(excluding a5).
The benefit would be little overhead in routing. Negative point would
be possible uneven distribution.
Thoughts?
