XDS Architecture
The following diagram presents the XDS architecture with:
one XiVO Main
one CTI / Reporting Server (XiVO CC)
and three MDS
As you can see:
each MDS and the Main are linked together via an internal SIP trunk (the yellow lines) - via the VoIP IP Address of the MDS
the xuc components of the CTI / Reporting Server is connected to each MDS AMI - via the VoIP IP Address of the MDS
Database Replication
Database replication is employed by the mds to receive replicated data from XiVO Main.
The mds use PostgreSQL replication to synchronize data with XiVO Main.
To control the replication process, the max_slot_wal_keep_size parameter is set to 1G. This means that if a mds becomes unavailable and falls too far behind, it will not be able to continue replication.
For more detailed information on PostgreSQL replication configurations, please refer to the PostgreSQL documentation.
