Implemented products

  • Comarch Network Inventory Management constitutes the basis for other modules which operate using data collected and stored in its database. It is designed to store complete information on network resources. The information is kept up-to-date with changes occurring in the network thanks to the integrated network reconciliation module.
  • Comarch Network Configuration Management supports the configuration of network elements of O2 network infrastructure in Germany. The functions of this module cover: software/firmware management including scheduled upgrades, direct configuration of each of the network elements via a dedicated GUI, population of the initial configuration of new devices as well as modeling and provisioning of End2End connections.
  • Comarch Fault Management module monitors existing network elements that constitute the network infrastructure. It receives, displays and efficiently tracks alarms, all of which allows users to manage potentially debilitating network problems quickly and effectively. The system also enables users to fully configure the way alarms are processed. This is done through the creation of rules utilized by the built-in correlation engine.
  • The main goal of Comarch OSS Performance Management (PM) is to provide a centralized point of performance policy monitoring and network performance reporting. Here, the module focuses on collecting all performance data (both short- and long-term) and forwarding it to O2‘s central PM data analysis system.
  • As for the presentation of gathered data, a sophisticated visualization interface was provided. This interface is capable of displaying all elements and alarms. However, apart from simply listing devices and alarms, it is also possible to use maps in order to visualize the status of network infrastructure and services. The system offers a GIS map-based visualization, logical layout as well as a hierarchical view of the network and the devices within.

The results

The implementation of the Comarch OSS Suite was followed by a set of benefits including:

  • Centralized and unified control across all network domains
  • Information on network elements and their configuration gathered in one place
  • Seamless integration with the existing environment
  • Unified solution for real-time network performance management and monitoring
  • Improved network reliability
  • Full automation of fault management tasks, including correlation
  • Future-proof design (easy extensibility)

Thanks to the wide scope of its functionalities, the Comarch OSS Suite is a sure step towards an integrated network management system, simplifying the management process and reducing OPEX.
