Analysis of the effect of delay and window size on TCP connection efficiency
Kavický, Martin ; Komosný, Dan (referee) ; Molnár, Karol (advisor)
Content of master’s thesis is description field of Sliding window and it’s expansion algorithms, witch are Slow start, Congestion avoidance, Fast Retransmit and Fast Recovery algorithm. Thereinafter is described creation of model in Opnet Modeler’s simulation area. In this simulation area was analyzed reactions of average transfer speed onto variance of data size, lost ratio, latency in short and long time slot and variance of receiver’s buffer size. In last section of this document is method design witch makes it possible of transfer speed control through the use of receiver’s buffer size dynamic setting.

Measurement of transfer speeds and delays in computer networks
Bárdossy, Adrián ; Kubánková, Anna (referee) ; Jeřábek, Jan (advisor)
Bachelor thesis is interested in measurement of transfer rate and latency in computer networks. In the first part of thesis is defined, which motodics of measurement we know, various RFC and their specifications, also various parameters about measurement in computer networks like bit rate, capacity of channel, latency. In the second part are prepared users interfaces and softwares for applying the measurement of thesd parameters. In the last part is application of these softwares and creating and testing methodic of network measurement.

Performance and security analysis of Wireguard technology
Varga, Oliver ; Holasová, Eva (referee) ; Krajsa, Ondřej (advisor)
This thesis deals with the description of WireGuard virtual private networks technology, its comparison with the technologies IPsec and OpenVPN based on the encrpytion algorithms they use to ensure security and also compares their technical parameters such as latency, jitter and transfer speeds. The work includes a description of the WireGuard technology, a comparison of the mentioned technologies and finally the results of the measurements of their technical parameters. The methodology chosen by us for testing the parameters, the hardware used to obtain the results and the network topology are also described. Finally, the results obtained from the tests are compared.
