Ovaj diplomski rad opisuje teorijsku podlogu Ethernet komunikacije kao i provedbu analize TCP/IP protokolskog stoga za 100 Base-TX Ethernet na TTTechovoj TTA-Drive ploči. Analiza se provodila nad komunikacijom dva procesora na TTA-Drive ploči u tri faze: analiza maksimalne brzine slanja podataka, maksimalne brzine primanja podataka i analiza obilaska mreže. Analiziran je utjecaj Linux raspodjelitelja zadataka (engl. Scheduler) na performanse slanja, problem omjera korisnog sadržaja i zaglavlja podatkovnog paketa (engl. Goodput), ukupne propusnosti (engl. Throughput) i povećanje vremenskog kašnjenja (engl. Latency) za različite duljine podataka. Na temelju provedene analize moguće je predvidjeti ponašanje sustava u određenim uvjetima i na taj način poboljšati arhitekturu programske podrške za navedenu ploču. ; This thesis describes the theoretical background of Ethernet communication as well as the implementation of TCP/IP protocol stack analysis for 100 Base-TX Ethernet on the TTTech TTA-Drive board. The analysis was conducted over the communication of two processors on the TTA-Drive board and in three phases: the analysis of maximum send rate, maximum receive rate and round-trip analysis. The impact of the Linux scheduler on the performance of sending data, the problem of the ratio of useful content and package header (Goodput), the overall Throughput, and the increase of the latency for different lengths of data were analyzed. Based on the performed analysis, it is possible to predict the behavior of the system under certain conditions and thus improve the architecture of the program support for the specified board.
