  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 NDA’s • 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 willneed 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+) • XML’izing the port numbers registry
