Deployment Scenarios

Two basic deployment scenarios exist for the SBC Software Edition routing and policy management. 

  1. SBC SWe running exclusively on a server.
  2. SBC SWe co-hosted with other virtualized applications on a server.

Routing and Policy Management

The two basic configurations for routing and policy management are:

Centralized Ribbon Policy Server (PSX) 

The centralized PSX server combines call routing  functionality with exceptional capacity of storing tens of millions of call routes in a single database. This SBC-Centralized PSX deployment distributes that routing intelligence to every PSX server in the network and simplifies the provisioning process.

For more information on Ribbon Policy Server (PSX), refer the PSX Policy Server Documentation.
For information on how to configure SBC to use an external PSX, refer Configuring SBC for External PSX.

The below figure depicts the SBC deployed with an external PSX and an EMS.

Embedded Routing Engine (ERE)

The ERE provides less routing and policy management functionality and is intended for smaller networks with no complex routing needs.
