Test SummaryIPv6 performance is inferior to IPv4The Cisco router enables IPv6 routing based on software not hardware6to4 tunneling performance is very poor but Cisco 6PE performance is goodThe MPLS labeling doesnt affect the performance of IPv6.

Conclusion What we have doneTest and verification of IPv6 protocolsTest and verification of IPv4/IPv6 transition mechanismsThe performance evaluation of IPv6 equipmentDesign and operation of the Koreas first native IPv6 networkWhat we will doProvide IPv4/IPv6 migration plan and IPv6 deployment strategyDevelop IPv6 applications and services Provide field trial prior to commercial service
