20.500.12556/DKUM-38045 PRIMERJAVA PROGRAMSKIH IN STROJNIH EMULATORJEV NA OMREŽJU IP COMPARISON OF SOFTWARE AND HARWARE-BASED POCKET-LOSS EMULATORS IN IP NETWORKS Diplomsko delo analizira emulatorje napak na IP-omrežju. V ta namen smo umetno generirali promet z uporabo odprtokodnega programa D-ITG, pri čemer smo uporabili programski in strojni emulator napak, ter primerjali rezultate. Analizirali smo najpogostejše scenarije izgubljanja prometa na IP-omrežju, hkrati pa smo se omejili na tri različne kodeke, za katere smo postopoma povečevali število sej z generatorjem prometa D-ITG. Rezultati so pokazali razlike med strojnim in programskim emulatorjem napak. Odstopanja so predvsem v programskem emulatorju napak in so posledica uporabljene strojne opreme. V diplomskem delu so podane tudi splošne značilnosti uporabljenih orodij, njihove funkcije in nekatere omejitve. The work presents the analysis of packet loss in IP networks. We artificially generated traffic using open source generator D-ITG and software and hardware network impairment emulators, which we compared to each other. We demonstrated the most common scenarios in IP network. We focused on three different codecs, for which we gradually increased the number of traffic sessions with generator D-ITG. The results showed us difference between hardware and software network impairment emulator. Reasons for differences between them can be found in the dependencies of software emulator on hardware components used. In this work we also give some general characteristic of tools which were used, their functions and their restrictions. izguba paketov programski emulator napak strojni emulator napak generator prometa IP-omrežje. packet loss traffic generator software network impairment emulator hardware network impairment emulator IP network true true false [J.
