Slide 3 3 3 Introduction IPv6 activities in KT 1999 KT have got
first commercial IPv6 address allocation in Korea 1999 Koreas first
native IPv6 network on KOREN (Technology laboratory) 2001 Mobile
IPv6 Test (Multimedia laboratory) Slide 4 4 4 Background We want to
minimize the investment for IPv6 Consider using legacy network and
idle equipment for IPv6 Need the information about IPv6 performance
on legacy network Determine IPv6 deployment strategy based on the
performance test result Slide 5 5 5 Transition Mechanism for Test

(Cisco 6PE) Slide 17 17 Test Configuration & Results IPv6 over
MPLS (Cisco 6PE) Slide 18 18 Test Summary IPv6 performance is
inferior to IPv4 The Cisco router enables IPv6 routing based on
software not hardware 6to4 tunneling performance is very poor but
Cisco 6PE performance is good The MPLS labeling doesnt affect the
performance of IPv6. Slide 19 19 Conclusion What we have done Test
and verification of IPv6 protocols Test and verification of
IPv4/IPv6 transition mechanisms The performance evaluation of IPv6
equipment Design and operation of the Koreas first native IPv6
network What we will do Provide IPv4/IPv6 migration plan and IPv6
deployment strategy Develop IPv6 applications and services Provide
field trial prior to commercial service
