Abstract

Stoga cilj ovog rada je modeliranje raznih Diameter prometnih scenarija unutar Rx i Gx sučelja koriteći četiri osnovne statističke distribucije, kako bi se što kvalitetnije ispitale preformance PCRF servera. Opisani modeli prometa implentirani su unutar programskog riješenja koji je bio suradnja između Fakulteta elektrotehnike i računarstva the Siemnse CVC-a. Također važna stavka programskog riješenje je implementiran algoritam dimenzionranja testne okoline, tj. potrebnog broja testnih agenata u rasprostranjenoj okolini. Konačno u posljednjem poglavlju prikazani su rezultati simualcija, gdje je cilj bio validirati ostvareno programsko riješenje, prikazavši grafički generirani promet za svaku distribuciju.
Sve u svemu cij ovog rada je razviti programsko riješenje omogučiti korisniku novi način testiranja PCRF servera koristeći različite sequence Diameter poruka, te različite distribucije za generiranje tih sequenci poruka.

Abstract (english)

The goal of this master thesis work is to examine the most frequent Diameter traffic scenarios inside the PCC entity. To provide the adequate AVP values for the messages exchanged on the Gx and Rx interface, and finally to model the Diameter traffic based on the implemented Diameter messages and adequate AVP values inside the messages. Once the Diameter traffic is modeled the further step is to define the statistical distributions and their adequate parameters based on which the modeled Diameter traffic shall be generated in the test agents. Also as part of the software solution the test agent dimensioning algorithm was provided to enable Diameter traffic generation on a distributed environment. Also the user will be able to receive partial statistical results on demand, and final statistical report when the simulation finishes.
All in all this work enables to the user to test the PCRF server with various statistical distributions and Diameter traffic scenarios, providing performances and stress testes of the PCRF server.
