The following errata report has been submitted for RFC5847, "Heartbeat Mechanism for Proxy Mobile IPv6". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=5847&eid=2302 -------------------------------------- Type: Technical Reported by: Alfred Hoenes <ah@TR-Sys.de> Section: 3.1, pg. 5 Original Text ------------- A PMIPv6 node (MAG or LMA) matches every received Heartbeat Response to the Heartbeat Request sent using the sequence number. Before sending the next Heartbeat Request, it increments a local variable << page break >> | MISSING_HEARTBEAT if it has not received a Heartbeat Response for the | previous request. When this local variable MISSING_HEARTBEAT exceeds a configurable parameter MISSING_HEARTBEATS_ALLOWED, the PMIPv6 node concludes that the peer PMIPv6 node is not reachable. If a Heartbeat ! Response message is received, the MISSING_HEARTBEATS counter is reset. Corrected Text -------------- A PMIPv6 node (MAG or LMA) matches every received Heartbeat Response to the Heartbeat Request sent using the sequence number. Before sending the next Heartbeat Request, it increments a local variable | MISSING_HEARTBEATS if it has not received a Heartbeat Response for | the previous request. When this local variable MISSING_HEARTBEATS exceeds a configurable parameter MISSING_HEARTBEATS_ALLOWED, the PMIPv6 node concludes that the peer PMIPv6 node is not reachable. If a Heartbeat Response message is received, the MISSING_HEARTBEATS counter is reset. Notes ----- Rationale: The RFC text varies between singular and plural form of the name of the local variable. A single name is necessary for consistency. Paraphrasing from MIB doctor guidelines, counter variables should always be in plural form. Additionally, the related configurable parameter is called "MISSING_HEARTBEATS_ALLOWED " in the RFC. Therefore, "MISSING_HEARTBEATS" is chosen above as the appropriate form and the instances of "MISSING_HEARTBEAT" are changed to the plural form. 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. -------------------------------------- RFC5847 (draft-ietf-netlmm-pmipv6-heartbeat-07) -------------------------------------- Title : Heartbeat Mechanism for Proxy Mobile IPv6 Publication Date : June 2010 Author(s) : V.
