Session Load Balancer and Route Manager Overview

The Session Load Balancer and Route Manager (SLRM) is a component of the Oracle Communications Core Session Manager software that allows the network architect to establish a front end to multiple Oracle Communications Core Session Managers acting as S-CSCFs.

IMS deployments typically use many S-CSCFs, often dispersed geographically, to provide location services for large numbers of endpoints. Oracle allows you to configure one or more Oracle Communications Core Session Managers as SLRMs to streamline endpoint access to S-CSCFs. A key extension over a standard I-CSCF is the ability of the SLRM to load balance between Oracle Communications Core Session Managers configured as S-CSCFs, thereby preventing any given S-CSCF from becoming overburdened. The user can configure any Oracle Communications Core Session Manager as an SLRM without restriction. An SLRM can perform the functions of an I-CSCF, but cannot perform the functions of an S-CSCF.

See the Session Load Balancer and Route Manager chapter for complete explanation and configuration instructions on the SLRM configuration.
