RNI 2.2.4 Software Architecture
RNI Architecture Update
• RNI 2.x platform is based on a proven traditional
software architecture
• Dependent on its database as the hub of all
information
• Scalability is achieved by deploying specific sub
components to a dedicated server
• RNI 2.x employs several operating systems—Red Hat
Enterprise Server (Linux), and Windows Server 2003
6
Deployment Sizing Estimates: RNI 2.2.4
RNI Architecture Update
• Focused on number of end points and service types
to determine deployment sizing

RNI 3.x Software Architecture
RNI Architecture Update
• RNI 3.x platform is based on the Service-Oriented
Architecture (SOA) model
• Software services can be used across any number of
hardware servers, or co-exist in a smaller
configuration
• RNI 3.x employs several operating systems—Red Hat
Enterprise Server (Linux), Windows Server 2008, and
Windows Server 2003
8
Deployment Sizing Estimates: RNI 3.1 SP1
RNI Architecture Update
• Focuses on the following factors to determine
deployment sizing:
– Amount of incoming Over-The-Air (OTA) data
˃ Number of end points
˃ Configuration of end points (amount of data transmitted)
˃ Network configuration (number of times RNI hears same message)
– Amount of data stored
˃ End point data (indefinite)
˃ Interval, billing and alarm data (60 days)
˃ Statistical data (13 months)
– Amount of data being exported
˃ To static reports (how often and volume)
˃ Through gateway to an MDM (real-time)

RNI 3.1 SP1 Deployment Sizing Example
RNI Architecture Update
• Using the number of OTA messages and transmission
rate determines an estimate of the number of end
points that can be supported
