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

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
