REVISED Port Number Procedures DRAFT

1
REVISED Port Number ProceduresDRAFT

• TSVAREA WG Meeting
• Vancouver, IETF-70
• Presented by Michelle Cotton, IANA

2
Current Guidelines

• Currently defined in RFC 2780 but not clear
• Ports assigned via IANA paid expert reviewer
  (no other registry has this)
• Currently allow NDA - This causes issues when
  having an official expert designated
• Assign both the TCP and UDP
• Guidelines for SCTP and DCCP are different

3
Proposed Guidelines

• IANA requesting official designation of expert(s)
  by the IESG
• NO NDAs
• Port number space conservation and clarity
• Only assign what the requester is asking (example
  UDP only) and reserve the others
• Approximately 15-20 ports assigned in November
  October
• Not retroactive

4
Remaining issues

• A discussion distinct from the port registry
  update document will need to define how port
  number allocation interacts with service names
• Requests for service names without number
• Renaming existing ports
• (eg. Reusing port number for new protocol)
• Well known (0-1023) vs. Registered (1024)
• XMLizing the port numbers registry
