Some Observations on the Performance of SCTP-controlled Failovers in M3UA-based SIGTRAN Networks

摘要: With Voice over IP (VoIP) emerging as a viable alternative totraditional circuit-switched telephony, it is vital that the twoare able to intercommunicate. To this end, IETF SignalingTransport (SIGTRAN) group has devised an architecture forseamless transportation of SS7 signaling traffic between aVoIP network and traditional telecom network. However,at present, unclear if SIGTRAN will,in reality, meet requirements, especially stringentavailability requirements.The SCTP transport protocol one core componentsof architecture, its failover mechanism isone most important availability mechanisms ofSIGTRAN. Currently, we are studying performance ofSCTP-controlled failovers, although study not yetcompleted some observations have been made on propertiesof which could impede itsperformance. This paper reports these observations, andexplains their causes.
