  4. IVI presentations in previous APNIC meetings

  5. Translation technologies • 1:1 IVI • Stateless in the core • 1:N dIVI • Stateless in the core • Partial state in the edge • Can save IPv4 addresses • No need for ALG Vendor supports

  6. IETF standard process

  10. IPv4/IPv6 core IPv6 MAN BRAS CPEs SP trial • SP: • Stateless in the core • IPv6 single stack access network • Use public IPv4 address effectively • Simple log • User: • A fractional IPv4 (1/128) • 512 concurrent sessions • No need for DNS64 • No need for ALG • A /64 IPv6 • 64K concurrent sessions
