The Server Manager builds a topology of the deployed vIMS components. The topology objects represent the vIMS deployed VNFs, their relationships, and their association with tenants and virtual infrastructure.
vIMS topology objects include:
- CallSessionControlFunction: The Call Session Control Function (CSCF) in IMS comprises three distinct roles: the Proxy CSCF (P-CSCF), the Interrogating CSCF (I-CSCF), and the Serving CSCF (S-CSCF). The CSCF is implemented via servers using the SIP protocol to communicate with each other and application servers.
- HSSMirrorFunction: A primary user database that supports IMS network entities that actually handle calls.
- XMLDocumentManagementServer: Allows operators to maintain their subscriber's profile information in a central, secure and easy to access repository.
- VIMSApplicationService: Represents vIMS application.
CallSessionControlFunctionsGroup: CallSessionControlFunctionsGroup is a group of CallSessionControlFunction collectively provides redundancy.
- HSSMirrorFunctionGroup: HSSMirrorFunctionGroup is a group of HSSMirrorFunction collectively provides redundancy.
- XMLDocumentManagementServersGroup: XMLDocumentManagementServersGroup is a group of XMLDocumentManagementServer collectively provides redundancy.
- VIMSApplicationServiceGroup: Group of VIMSApplicationServiceGroup Processes that together provide a service.
IPMultiMediaSubSystem: It is a framework for delivering IP multimedia service.
- VNFManager: VNF Manager provides the essential management and orchestration capabilities needed to deliver VNF-based network.
- Orchestrator: Orchestration is the automated configuration, coordination, and management of virtualized network components and software.
- Tenant: User of cloud computing service, who shares resources and cost of underlying hardware resources like compute, storage and network with other users.
