The QBus Platform (QP) software provides an execution environment for Java-based applications, which are the Multiprotocol Routing Agent (MRA) devices, Multimedia Policy Engine (MPE) devices, or the Configuration Management Platform (CMP) server. QP provides common interfaces into databases, event logging, SNMP, and cluster state. Two servers in the cluster provide 1+1 High-Availability (HA) protection. The application executes on one server. The other server acts as a hot standby in case the first server fails to provide service.
