SPECTS_Summary
The wide spread of high speed access technologies evolves a mass market of broadband Internet services. 3play service concept targeting this market covers voice, data and video delivery on the same packet based service platform. To upgrade current IP core and aggregation networks in order to meet enhanced service availability and quality requirements of voice and video services, the evaluation of related currently available network capabilities may provide the starting point. On the other hand, to guide efficient developments, the analysis of designed networking solutions is required, as well. These considerations significantly increase the need for efficient network analysis support in real market oriented processes. Current paper introduces an availability and QoS analysis framework developed and applied real for size networks. The main scope of the presented work is on the adaptation of theoretical availability and QoS analysis methodology for realistic cases. Both problem size and complexity reduction, as well as efficient worst case estimation approaches are considered to cope with difficulties of large size real network analysis problems. Adaptation of analysis methodology for a desktop GRID is overviewed. Numerical examples are presented to illustrate the size, complexity and structure of the problems to be solved. The integration of the analysis support into real network development environment is considered, as well.
