Abstract

U ovome radu prikazana je arhitektura OSI (Open Systems Interconnection) modela i TCP/IP (Transmission Control Protocol / Internet Protocol) složaja. Objašnjeni su slojevi i njihove funkcije, te opisani najznačajniji protokoli koji se nalaze na svakom od slojeva te njihove zadaće i način rada. Mjerenje mrežnog prometa te praćenje toka paketa pruža velik broj mogućnosti upravljanja i kontrole mreže, npr. korištenjem ovih funkcija moguće je primjerice uočiti razne anomalije unutar mreže, riješiti probleme koji usporavaju mrežu, kreirati stvarno vremenske ili povijesne zapise o događanjima unutar mreže. Stoga, izrađena je aplikacija za tu namjenu te su njen postupak izrade i način rada u cijelosti objašnjeni kao i funkcija svakog pojedinog elementa koji se nalazi unutar grafičkog sučelja. Prikazan je način rada same aplikacije te njene mogućnosti pri prikupljanju i filtriranju prometa kao i prikaz informacija o prikupljenim paketima.

Abstract (english)

This paper presents the architecture of OSI (Open Systems Interconnection) model and TCP/IP (Transmission Control Protocol / Internet Protocol) suite and explains the functions of the protocol suite layers. The most important protocols on each layer are described, as well as their tasks and the way they work. Measuring network traffic and tracking packet flow provides a large number of network management and control options, e.g., using these functions it is possible to detect various anomalies within the network, solve problems that slow down the network, create real-time or historical records of events within networks. Hence, a traffic monitoring application is created whose process of development is explained, including the use of the application itself, as well as the function of each individual element located within the graphical interface. Use of the application is shown, including its ability to capture and filter network traffic while displaying information about the captured packets.
