The document discusses the transition from IPv4 to IPv6, noting that IPv6 is not backward compatible, leading to a coexistence period of both protocols. It evaluates various transition technologies such as MAP-E, MAP-T, DS-Lite, and 464XLAT in different network environments, highlighting their performance in terms of latency and throughput. The study also emphasizes the need for enhancements in the operational capabilities of these transition implementations before their use in production networks.
