2.2 DSR system architecture

The following image shows an overview of a DSR system architecture. Only single elements are shown for simplicity.

Figure 2-1 DSR 7.x Architecture

The key components of the solution are:

• Operations, Administration, Maintenance, and Provisioning (OAMP)
  • System OAM per signaling nod
  • Network OAMP
• Diameter Agent Message Processor (DA MP) (handles Diameter and Radius)
• SS7 Message Processor
• STP Message Processor
• IP Front End (IPFE)
• Session Binding Repository (SBR)
• Database Processor (DP) / Subscriber Data Server (SDS)
• Query Server (QS)
• Integrated Diameter Intelligence Hub (IDIH)
• User Data Repository (UDR NO)–Optional
• VNF Manager (VNFM)–Optional
• Service Proxy Function (SPF) and NRF (Network Repository Function)–Optional

List of non-compatible features in DSR 8.3:

• Diameter Intelligence Hub (DIH)
• Gateway Location Application (GLA)
• Radius

  In rest of this document any reference to these non-complaint features shouldn't be considered for feature enabling.

  These components are described at a higher level in the following subsections. Although each component plays a key role, the OAM and DA MP components are the mandatory components of the system.
