Session Load Balancer Support

In order to rapidly increase the number of supported endpoints, the Oracle Communications Unified Session Manager can interoperate with the Oracle Communications SLB. When paired with an Oracle Communications SLB, the Oracle Communications Unified Session Manager maintains its ability to function with an HSS or ENUM database.

In addition, the Oracle Communications Unified Session Manager and Oracle Communications SLB pair supports Cx or ENUM based registrations.

To communicate with an Oracle Communications SLB, in addition to all baseline Oracle Communications SBC SIP functionality, the Oracle Communications Unified Session Manager advertises its registration capacity to the Oracle Communications SLB. This value is defined in the SIP interface as the reg cache limit parameter. Since the Oracle Communications Unified Session Manager has a database registrar license, the lower of the two will be advertised to the SLB.
