Estratégia de migração para IPV6: análise de implantação do dual stack

Abstract

The transition to IPv6 has become a problem to the Internet due to the passivity of companies to make the protocols switching. The delay of this transition has worried the regulatory authorities since the available IPv4 address blocks are exhausted. The present paper presents a migration strategy to IPv6 through the dual stack method. To demonstrate that dual stack can be acceptable and recognized as the best migration method some tests were executed comparing with another transition method, the tunneling, represented by 6over4. The tests involve measures of jitter, latency and hardware resources, and there are also three failure tests which are protocol flap, reboot and link failure. The results indicate similar performance between both methods, but with an advantage to the dual stack considering the ease of deployment, performance of router processor and the low impact on the network. The major disadvantage was because of RAM memory utilization compared to 6over4 on the used routers during the tests.
