Management of large communication networks: A case study

Ivan Vrana, Jan Vrána

In the previous paper [6] authors outlined three basic implementation methods and discussed aspects of how to compare suitability of different approaches for building and operating a system, which supports a telecommunication network configuration management. Based on those evaluation criteria this case study will assess and compare main features and effectiveness of individual alternative implementation methods. It is explained, why the implementation method of the Dynamic relational data storing has proven the most efficient out of the three alternatives. This method was successfully implemented in Eurotel (currently Telefonica O2) network management and this implementation enabled an immediate view on all managed network settings, a dramatic speedup of most activities, reduction of errors, better exploitation of capacity of individual network elements and significant reduction of hardware costs. The method could be generally utilized for solution of a broad category of real problems.
