Hi Brian, Hi All, Is it useful to have SCTP multihoming on M2PA links between Signalling Transfer Points/Gateway (STPG)? I see in the IETF RFC that multihoming on M2PA has been taken into account as a possibility. Is this possibility advisible, without being harmful for the Network ? I also read that It is possible that transmission of M2PA messages MAY be delayed by SCTP slow start under certain conditions, like Path failure (multi-homing) if SCTP switches to a new path. (<draft-ietf-sigtran-m2pa-09.txt>) I'm now in doubt, because a supplier of STPG's told me that often customers do not use multi-homing for M2PA associations because redundancy is already provided at MTP Layer 3 (Changeover procedures). The supplier claim that M2PA multi-homing can actually make configuration more complicated because of timers for RTT (at SCTP level) and COO, CBO at MTP layer 3. Do you have any argumentation or practical explanation to this claim? Who can advise me why to Implement Multihoming OR NOT Implement Multihoming in a Sigtran M2PA Network connection?
