Abstract [sv]

Antalet tillgängliga IPv4-adresser håller i dagsläget på att ta slut och det ärdärför nödvändigt att hitta en metod för att migrera nätverket till den nyastandarden, IPv6. En migrering kan kräva att de två IP-versionerna måsteanvändas i nätverket simultant, för att de system som är beroende av nätverketska vara tillgängliga. Syftet med arbetet var att undersöka prestandani de olika migreringsteknikerna, samt att få fram vilka tekniker som är attföredra. Med hjälp av två scenarion, uppsatta i labbmiljö, testades migreringsteknikernasprestanda med verktyget Iperf. 6to4 och GRE testades iden ena miljön samt NAT64 och Teredo i den andra miljön. De nätverksegenskapersom analyserades var throughput, jitter samt packet loss. Resultatenvisade på att 6to4 och GRE är näst intill jämlika men att 6to4 haraningen bättre throughput än GRE. Större skillnad var det mellan NAT64och Teredo, där Teredo kunde uppmätas till en mycket högre hastighet medUDP-trafik än NAT64. När TCP användes var dock NAT64 något snabbareän Teredo.

Abstract [en]

The number of usable IPv4 addresses is in the current situation sufferingfrom exhaustion and it is therefore necessary to find a way to migrate thenetwork to the new standard, IPv6. A migration may require that the two IPversions must be run on the network simultaneously, to make sure that systemsthat are dependent on the network are running stable. The purpose ofthis study was to examine the performance of the different migration techniques,and find out which techniques are preferred. With the help of twoscenarios that were used in a test bed, a performance test was done usingthe Iperf tool. 6to4 and GRE were tested in one environment and NAT64and Teredo in the other environment. The network properties analyzed werethroughput, jitter and packet loss. The results showed that the 6to4 and GREare almost equally balanced but 6to4 has slightly better throughput thanGRE. A much more notable difference could be seen between NAT64 andTeredo, were Teredo was measured with a much higher transmission rate ofUDP traffic than NAT64. However, when TCP was used, NAT64 wasslightly faster than Teredo.
