Comparison of Linux and Windows networking performance
Novotný, Radek ; Burget, Radim (referee) ; Komosný, Dan (advisor)
My Bachelor’s thesis aims to provide a comparison of the performance of servers, i.e. measuring the load of their processors, physical memory, and the whole operating system over network communication using UDP protocol. For this purpose, I developed my own programs. Theoretical part of this work concentrates on the general overview on computer networks and their categorisation according to the ISO OSI and TCP/IP network models. Main differences between network interfaces for both models are provided; the TCP and UDP structures, layers, communication and protocols are explained. The choice was made to measure values for a Linux server with Linux SUSE 10.3 distribution, and a Windows server with Windows server 2003 R2. A program was created so that clients could send data via the UDP protocol on servers. The program is also capable of measuring packet loss which is caused by increased load on the servers from communication itself. It is essential to determine which operating system can eliminate this issue in a better way as this a crucial parameter when selecting a data server. Measurements are comprised in charts comparing load and data loss for a given number of users.
