Chapter 5. Clustering

5.1. Failover
5.2. Load Balancing

SMPP RA doesn't replicate the SmppTransaction activity for failover. This is due to inherent nature of SMPP Protocol which is peer-to-peer

SMPP RA implements the HA API (FaultTolerantResourceAdaptor) of Mobicents JSLEE. Same entity of SMPP RA can be started in different cluster enabled nodes of JSLEE to take care of load balancing.
