baseline
Baseline
  • First Presented in BEHAVE at IETF78 – Maastricht
  • Presented to OPSAWG at IETF83 – Paris
  • Accepted as OPSAWG WG Document
  • Potential Move to SUNSET4 in the future (up to AD)
    • (did not exist at the time)
  • Show real world implementation option for CGN (based on NAT444 Model)
  • Includes models for IPv6 Dual Stack with CGN/NAT444
  • Can be used in Wireless or Wireline domains
status
Status
  • Some, but not too much chatter (comments) on draft from WG
  • Move to SUNSET4 unknown at this time
  • Model in document in production (Wireless/Wireline environments)
  • Move comments welcome (to clean up document)
basic model diagram
Basic Model (Diagram)
  • CGN Traffic in IP VPN (BGP/MPLS)
  • Post translated traffic on Global (Internet) routing table
  • Allows separation of legacy IPv4 and CGN IPv4 traffic
  • Utilizes common operation technologies
  • Provides efficient way to accomplish CGN by-pass
  • CGN hardware can be located anywhere on network (no policy routing required)
dual stack concept with lsn diagram
Dual Stack Concept with LSN (Diagram)
  • Supports dual stack operation if IPv6 is needed with CGN/NAT444
next steps
Next Steps
  • Further comments welcome
  • Is Document read to progress?
  • When to move to WGLC?
