Network Emulator of Transmission Parameters of Data Networks

Abstract

This article deals with development of a network emulator of transmission parameters of data networks working with the TCP/IP protocol suite. The article contains a specification of transmission parameters of data networks and a specification of currently developed open-source systems, which can be used to emulate transmission parameters of data networks. Further, the design and implementation of the network emulator is described. The proposed network emulator uses Traffic Control, NetEm, iptables, web service and Apache JMeter. The graphical user interface (GUI) of the network emulator is implemented by a web service and a module to the GUI of the stress tester Apache JMeter. The article also deals with measurement of transmission parameters of data networks using the developed network emulator and the Station A and Station B. The measured values are discussed.
