[Sigtran] Query regarding the sequence message delivery functionality in M3UA layer

[Pradeep Kumar <[e-mail]>]

Hi,



I had an query regarding the sequence message delivery functionality in
M3UA layer.



As in the SS7/MTP3 layer there is concept of the controlled re-routing in
case of links status un-availability, the controlled re-routing buffer and
its time controlled procedure ensures that that are messages are delivered
in-sequence.  As explained in the RFC section 8.1.1 of T-REC-Q704 as :

*“**8.1.1 **The objective of the controlled rerouting procedure is to
restore the optimal signalling*

*routing and to minimize mis-sequencing of messages. Therefore, controlled
rerouting includes a*

*time-controlled traffic diversion procedure,” *



Now in case of M3UA the same situation can occur, so do we have an similar
functionality of controlled re-routing available in M3UA/Sigtran as well?

If yes please mentioned the RFC section(I could not find any reference in
RFC on this topic). ?

              IF NO, then what is the reasoning behind not having the
controlled re-routing in M3UA/SIGTRAN? Is it so that we don’t need such
procedures in IP world and what is the reason for it?
