3 Oracle Communications Core Session Manager Basics

This chapter introduces some basic concepts that apply to the key features and abilities of your Oracle Communications Core Session Manager. It provides an overview of the concepts related to Oracle Communications Core Session Manager configuration and operation in your network as well as the functions it performs in an IMS core.

Oracle Communications Core Session Manager software allows for deployment as one of two available components:

  • Core Session Manager (CSM)—See the chapter titled Oracle Communications Core Session Manager Supporting the IMS Core for detailed information about Oracle Communications Core Session Manager configuration and operation in an IMS Core.
  • Session Load Balancer and Route Manager (SLRM)—The user can configure the software to operate as a proprietary Session Load Balancer and Route Manager (SLRM). An SLRM allows you to balance traffic between multiple Oracle Communications Core Session Managers. SLRM configuration and operation is covered herein under the chapter titled The Session Load Balancer and Route Manager and the Sc Interface Appendix.

Any given device can be only one component. There can be multiple SLRMs serving multiple CSMs, allowing product deployments to support the largest IMS environments.
