RE: Lossless fail-over

Jan,

I will try to summarize the rationale behind not having
changeover/changeback type of functionality in M3UA/SUA:
(there is an expired draft about M3UA deployment considerations, if you are
interested I can send you the relevant sections from it.)

a) Network failures are handled by SCTP + properly designed network.
b) Because of a) loss of SCTP association means peer going down.
c) When peer is down, changeover/changeback doesn't help -also not in
conventional SS7-.

   Thanks,
   Tolga

Subject: [Sigtran] Lossless fail-over


Hello everybody!
Is there any document specifying lossless fail-over or change-back
procedures in Sigtran especially in SUA?

I found out only expired draft-bidulock-sigtran-corid-03.txt. >From my point
of view this draft solves what I exactly need - but it is only expired
draft. How to solve it on inter-vendor level? Does anybody know why this
draft was leaved?

Thanks
Jan Kolomaznik
