NAT64 Performance Evaluation
Pokorný, Jan ; Veselý, Vladimír (oponent) ; Grégr, Matěj (vedoucí práce)
This thesis is focused on the challenges of the transition between IP protocol version 4 and IP protocol version 6. The transition can be solved by many transition mechanisms and this thesis thoroughly describe Stateful NAT64 transition mechanism. The thesis aims to test various implementations of NAT64 and find a suitable implementation for NETX router. The goal is to find an implementation that would achieve traffic throughput of about 10 Gbps. Several NAT64 implementations were evaluated in a testbed environment. Iperf and PF_Ring tools were used for throughput examination. Several different network traffic types have been measured to show the performance impact of each of the tested implementations. The results showed that the most suitable implementation of NAT64 is Jool. Jool reached the required throughput, its development is still active and offers other advanced features, thus Jool was integrated into the NETX router. A command line extension for manipulating Jool instance was designed, implemented and integrated to NETX command line. Additionally, a package distribution process was developed through the RPM package system to fit the NETX build system.The thesis outcome is full support of NAT64 transition mechanism in NETX platform achieving close to 10 Gbps.

Generation of IPv6 and ICMPv6 packets and their impact on the operation of network devices
Phan, Viet Anh ; Martinásek, Zdeněk (oponent) ; Jeřábek, Jan (vedoucí práce)
This master thesis is about researching the functioning of IPv6 (Internet Protocol version 6), ICMPv6 (Internet Control Message Protocol version 6), DHCPv6 (Dynamic Host Configuration Protocol version 6), NAT64 (Network Address Translation 64) and DNS64 (Domain Name System 64) protocols. The research process is carried out by setting up the network laboratory scenarios, in which stations exchange information via protocols of IPv6 family. Tools such as self-designed program, Ostinato application and Kali Linux machine are used to process and generate required types of IPv6 packets in specific circumstances. The results from the experiment are analyzed in order to provide network administrators or specialists a more complete understanding of function of IPv6 protocols, as well as possible vulnerabilities.
