1 IPv6 Networking Performance Issues

• IPv4 vs IPv6
• Lambda network vs Routed network
• TCP Reno vs. FAST TCP (vs. BIC TCP)
• Long distance (e.g., 20,000 or 30,000 km)
• KAIST-CERN(window size 30Mbyte)
• KAIST-Starlight(window size 20Mbyte)
• Single stream vs Multiple streams

13
TCP Reno vs. Fast TCP

• no significant difference due to small RTT
• Window size 1 Mbyte

  hosts? No native IPv6 multicast network yet in
  Korea
• Plan for the IPv6 Multicast testbed on 6GN
• 1st phase Tunnel based IPv6 multicast (e.g.,
  m6bone)
• 2nd phase Native IPv6 multicast (backbone level)

  IT839 such as WiBro, VoIP, and Home network
• Expanding IPv6 network to the public sector
• Transition of existing IPv4 portal sites and
  applications into IPv6 based ones
• Phase III (2006) Plan
• Providing large-scale All-IPv6 services to users
  as far as the 8 services of IT 839
• Supporting the commercialization of IPv6 WiBro
