Cisco Prime™ Central for Hosted Collaboration Solution (HCS) Assurance is a carrier-grade, extensible service assurance management platform for service providers deploying "as a service" solutions composed of Cisco® Unified Communications and collaboration applications in a hosted or cloud environment.
Service providers require a solution that monitors in real time the resources and services utilized by end customers. This solution provides a dashboard for a single-pane, multi-customer view of aggregated faults from underlying domain managers that span both unified communications (UC) and data center (DC) domains. This dashboard provides real-time root-cause analysis and correlates events across multiple unified communications and data center domains with customer-related service impact analysis. These fault correlation capabilities help triage issues and reduce mean time to repair (MTTR). Network operations center (NOC) operators also can quickly get detailed, actionable information on faults by performing a contextual cross-launch from the dashboard to the underlying domain managers. All of these capabilities are key to helping service providers meet service-level agreement (SLA) requirements and provide the highest quality of experience (QoE) to the end users of cloud-based services.
Cisco Prime Central for HCS Assurance also has the capability to feed information to other systems in the service provider environment such as trouble ticketing, manager of managers, and more. The solution includes support for standard interfaces and APIs to integrate easily with the service provider's OSS/BSS. The solution's northbound interface (NBI) provides a mediation layer that shields the OSS/BSS from changes to any underlying domain manager or collaboration service and saves the service provider from having to integrate to each individual domain manager.
Cisco Prime Central for HCS Assurance is part of a comprehensive management platform for the Cisco Hosted Collaboration Solution. See Figure 1.
Figure 1. The Cisco Prime for HCS Assurance Component of the Cisco Hosted Collaboration Solution
Cisco HCS is a next-generation unified communications and collaboration platform for service providers who want to offer unique Cisco collaboration technologies using hosted and managed models. More information on Cisco HCS is available at http://www.cisco.com/go/hostedcollab.
The Cisco HCS overall management architecture (see Figure 2) includes a service assurance component, Cisco Prime Central for HCS Assurance, as well as a service fulfillment component. These two components are integrated through the Shared Data Repository (SDR).
The service assurance interface to the HCS fulfillment subsystem offers two key functions:
• Provides a source of information about services, device inventory, and relationships used by Cisco Prime Central for HCS Assurance to allow events to be "enriched" with customer information
• Allows programmable customer onboarding and provisioning of Cisco Prime Central for HCS Assurance

Table 1 provides additional details on features and benefits of Cisco Prime for HCS Assurance.
Table 1. Features and Benefits
Intuitive interface to web-based dashboard.
• Eliminates the need to install client applications and manage upgrades on multiple client machines.
• Provides quick and easy access to information anywhere, any time.
• Certified on Red Hat Enterprise Linux operating systems.
• Ability to run on both virtualized (tested on the VMware ESXi hypervisor) and bare-metal (nonvirtualized) machines for large-scale deployments.
• Offers deployment flexibility.
• Provides for scalability through addition of blades and/or virtual machines (VMs) to allow for more customers and endpoint devices.
Common User Management and Administration
Single sign-on access to fully integrated domain managers
• Seamless access to the domain managers upon user authentication through the portal.
• No requirement for further authorization to access the different domain managers.
• Integration with external authentication servers, supporting Lightweight Directory Access Protocol (LDAP), TACACS+, and RADIUS plug-ins.
• Provides robust and simplified security through a central point of access for authentication and authorization control.
• Accelerates service assurance tasks.
Common user management services with role-based access control (RBAC)
Ability to assign user and group rights as well as associate roles/access rights to different components of the suite from a central location.
Helps enable efficient rollout of role-based assignments.
Common event/alarm management, de-duplication, normalization, and enrichment
• Rules and policies process incoming events from the underlying domain managers and normalize them to a common format for forwarding northbound. The normalized event is enriched with customer information.
• Single dashboard view and management of full alarm/event lifecycle without the requiring the network administrator to access the specific domain manager.
• Ability to navigate to the source domain manager for advanced troubleshooting.
• Helps network operators anticipate problems before the customer calls by promoting quick identification and diagnosis of the problem.
• Drastically reduces troubleshooting time and MTTR.
Monitoring HCS auxiliary applications including third-party products
Monitors the VMs, OSs, and processes of auxiliary applications (for example, an LDAP server or other servers used for security) as well as the network management applications.
This self-monitoring capability lets the operator know the state of the system at all times.
• The NBI saves the service provider from having to integrate to five separate domain managers.
• The NBI provides a mediation layer that shields the OSS/BSS from changes to any underlying domain manager or collaboration service.
• Cisco Prime Central for HCS provides two different types of northbound interfaces - normalized SNMP trap forwarding as well as web services APIs.
Extensibility promotes reduced overhead and time required for integration with BSSs/OSSs and other third-party products (for example, sending traps to ticketing systems).
• If Cisco Prime Unified Operations Manager changes its SNMP trap format, the service provider would have to invest and make the appropriate changes in its OSS. With Cisco Prime for HCS Assurance, the service provider OSS is shielded from these changes and no additional integration work is needed.
• When HCS adds a new collaboration service and introduces a new associated domain manager, integration between the service provider OSS and the domain manager would be required. With Cisco Prime Central for HCS Assurance, there is no new integration involved. The solution automatically recognizes any new events from the new collaboration service and sends normalized events northbound.
Simple Network Management Protocol trap forwarder
Ships with an integral SNMP gateway; simple plug-and-play integration for IBM Tivoli Netcool ("Netcool Ready").
• Simplifies integration with external OSSs by reducing the flood of alarms.
• Reduces integration costs.
• Decreased time to resolution of network/service issues.
• Traps can be simultaneously forwarded to multiple destinations (for example, a ticketing system, a reporting system) that are operated by different teams that need the same fault information.
NOC operator and network administrator common dashboard
Provides detailed information on the faulty situation across all network layers of the transport network for real-time fault management across all domains.
Fault information includes customer-centered, service-aware visualization.
• Easy-to-visualize format promotes ease of use and the ability to isolate faults quickly.
• Provides predefined views for operator to quickly group, identify, and isolate faults.
Cross-domain root-cause analysis
Provides root-cause analysis across both UC and DC domains. A rich data model, the SDR, is the basis for implementing root-cause analysis. Events from the underlying UC and DC domains are correlated based on the data model, which links the service fulfillment system with the service assurance system.
• Helps enable operators to identify barriers and the causes of problems so that permanent solutions can be found.
• Helps operators develop a logical approach to problem solving for more rapid fault correction.
Service impact analysis
The customer service dashboard visualizes service-level impact. Events from underlying domains are translated into service impacts by the customer.
• Prime Central for HCS Assurance rates the service impact by severity in a way that is easy for the operator to quickly determine what action to take.
• With a wide variety of services, it becomes essential to ensure that any outage is quickly reported to NOC experts so that MTTR can be reduced.
Provides the ability to filter alarms by domain manager, severity, time, customers.
Expedites troubleshooting and resolution of issues.
All events from underlying UC and DC domains are processed and the solution analyzes all cross-domain service-affecting problems. The following domain managers are supported:
• Cisco Prime Unified Operations Manager 8.6.2 focuses on fault monitoring and diagnosis of the broad portfolio of Cisco Unified Communications applications and infrastructure devices across multiple customers and allows operators to launch phones, alarms, the service-level view, or diagnostics test pages.
• Cisco Prime Unified Service Monitor, which is integrated with Cisco Prime Unified Operations Manager, monitors the voice-quality problems and provides call-analysis reports.
• Cisco UCS Manager covers the fault management for the Cisco UCS chassis and blades.
• Cisco Prime Data Center Network Manager (DCNM): DCNM-LAN monitors the data center devices such as Cisco Nexus® switches, and DCNM-SAN monitors the Cisco MDS storage switches.
