A complete EMS for the Corrigent line of Packet Add Drop Multiplexers

Improving Operational Efficiency with CM-View
CM-View is designed to significantly reduce the time and effort required for tasks related to service provisioning, service changes and diagnostics. Built upon carrier-class platforms and operating systems, CM-View is the first EMS designed for transport networks that are optimized for packet traffic.

Now service providers can provision services end-to-end from metro packet rings across an IP/MPLS core within seconds using service profiles that are assigned and controlled from a central location. SLAs and traffic profiles can be associated with customers then monitored and enforced automatically using flow-through provisioning tools provided in CM-View. Any level of topology view is available from the port, card, shelf, rack all the way through the domain and region. All these are displayed against automatically discovered and generated topology maps.

CM-View is capable of service provisioning, bandwidth management, in-service profile administration and many other tasks that previously required manual intervention to accomplish. Lead-times for new service provisioning with traditional SONET/SDH platforms often took weeks or months and required many man-hours of labor. With the Corrigent CM-100 Packet Transport Switch and CM-View these tasks can be accomplished in minutes. This reduction in ongoing operational expense and increase in service velocity is a critical requirement for profitable delivery of packet-based services.

Software Architecture
The CM-View architecture consists of a number of components that provide a full system for managing large, high-availability networks.

Components within this architecture include:

  • Client GUI
    The Client GUI incorporates HTML and a JAVA application and runs on an IE browser on each operator's workstation. The Client Java application allows dynamic and real-time updating of network status and alarms, while the HTML allows configuration and report generation.

  • Common Information Bus
    The Common Information Bus delivers information between the various distributed server entities using CORBA/IDLs.

  • Front-End Server
    The Front-End middleware supports a WEB server to enable WEB based GUI clients. The Front End Server (FES) uses servlet to process each GUI HTML request and generates the appropriate CORBA request to the Back End Server or to an SQL request for reports generator.

  • Back-End Server
    The Back-End Server components include the following levels: Network, Domain, Gateway and Meta Data Repository. These are described below.

  • Network
    The Network level includes all of the contract interfaces towards the Front-End Server (GUI components such as Fault, Topology, Configuration Inventory, etc.) or toward external OSSs. The Network level has a network view in terms of topology, connection and fonts.

  • Domain
    The Domain level includes the particular network element topology and the equipment operations to manage the network, node by node. The main scope of the Domain level is the underlying equipment and managed objects (network elements, such as the slots, modules, and interfaces).

  • Gateway
    The Gateway level has drivers for the RDBMS (Relational Database Management System). It includes all persistent data and historical statistics and SNMP drivers for the equipment. The data managed by the CM-view such as: Network topology, services and connections, alarms, performance monitoring, etc. is stored in the Oracle database.

  • Meta Data Repository
    The Meta Data Repository (schema or definitions) level includes the software representations of the managed objects data and operations supported by the system.
