The following errata report has been submitted for RFC5440, "Path Computation Element (PCE) Communication Protocol (PCEP)".
-------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=5440&eid=2941 -------------------------------------- Type: Technical Reported by: Ramon Casellas <[email protected]> Section: 10.7.1 Original Text ------------- o PCEP uses a single registered port for all communications. The PCE SHOULD listen for TCP connections only on ports where communication is expected. o The PCE SHOULD NOT allow parallel TCP connections from the same PCC on the PCEP-registered port. Corrected Text -------------- o PCEP uses a single registered port for all communications. The PCE MUST listen for TCP connections only on ports where communication is expected. o The PCE MUST NOT allow parallel TCP connections from the same PCC on the PCEP-registered port. Notes ----- RFC 5440 is not consistent regarding the use of RFC2119 keywords. In section 5 the RFC states "MUST" regarding the registered port and in section 10.7.1 it is stated "SHOULD". Section 10.7.1 seems to imply the PCE could listen at any port (which is technically possible, but not in line with the rest of the document). Finally, the restriction about multiple connections is confusing: Section 4.2.1 "Only one PCEP session can exist between a pair of PCEP peers at any one time" but section 10.7.1 uses "SHOULD NOT". Technically, without the TCP source restriction, it should be possible to accept multiple connections from a PCEP peer, but such a change could have broader implications Instructions: ------------- This errata is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party (IESG) can log in to change the status and edit the report, if necessary. -------------------------------------- RFC5440 (draft-ietf-pce-pcep-19) -------------------------------------- Title : Path Computation Element (PCE) Communication Protocol (PCEP) Publication Date : March 2009 Author(s) : JP.
