Kristian Zupan (2012) Transition mechanisms to IPv6. EngD thesis.
The aim of this bachelor thesis was the comparison between IPv6 transition mechanisms. The comparison was made between the two families of mechanisms: stateless NAT64 and stateful NAT64. We have compared two implementations: Tayga, which is a stateless NAT64 and Ecdysis, which is a stateful NAT64. Communication using diffrent application layer protocols from a node in IPv6 network to a node in IPv4 network was tested. Considering the quality of the transmision the protocols were arranged in three groups: well, conditionally and badly translatable. Additionally, effectiveness of address translation was measured and the differences were discused . An application level gateway, which enables us to use non translatable protocol FTP with stateless NAT64, was also implemented. It was designed as a supplement to a proxy server, performing the translation of FTP commands. Application level gateway was adequately tested and with its inclusion in the testing ground, we have proved that it is aslo possible to communicate from IPv6 network to IPv4 network with FTP protocol. In conclusion we have shown the importance of proper understanding and weighted choice of transition mechanisms in the networks of Internet service providers.
