!! Ok! A "round-robin" would be an acceptable solution if the servers
!! are all in the same (fast) network where, no matter what server is
!! given for a specific request, the performance would be more or less
!! the same.
!!
I agree. There have been some responses about the systems being
homogeneous... and "load balancing" software. If you read the paper,
we would LOVE to have a load balancing "round robin", and our servers
are NOT homogeneous, but do go through testing to make sure that they
can handle a certain load before becoming a web server.
!! But...
!! I have an AFS cell with file-servers spread all around Europe (uk,
!! fr, pt, de and nl). In this setup, a round-robin distribution of the
!! WWW servers would be silly.
I agree.!!!
!! Imagine someone working in UK asking for a
!! page available locally through AFS and the 'round-robin' DNS server
!! re-directs its request to the WWW server in... France. Not very smart!
!! The ideal solution would redirect the request to the server nearest
!! him (with the fast response timings).
!!
!! Is there a solution for this problem that takes in consideration the
!! connection timings between the requester and the server ?
!!
I think that the URN work that is going on here, and at many other cites
including CERN that will help solve that problem, but no currently I
don't know anything that would solve your problem. Sorry!

!! tks in adv & a Happy New Year !
