The following errata report has been submitted for RFC5225, "RObust Header Compression Version 2 (ROHCv2): Profiles for RTP, UDP, IP, ESP and UDP-Lite". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=5225&eid=2703 -------------------------------------- Type: Technical Reported by: Carl Knutsson <carl.knutsson@effnet.com> Section: 6.6.11 Original Text ------------- o ip_id_behavior, one octet for each IP header in the compressible header chain starting from the outermost header. Each octet consists of 2 bits padded with 6 MSBs of zeroes. Corrected Text -------------- o ip_id_behavior_outer, one octet for each IPv4 header except the innermost in the compressible header chain starting from the outermost header. Each octet consists of 2 bits padded with 6 MSBs of zeroes. o ip_id_behavior_innermost, one octet if the innermost header is an IPv4 header. The octet consists of 2 bits padded with 6 MSBs of zeroes. Notes ----- There is no control field called ip_ip_behavior in the document. There are two control fields related to IP-ID behavior, ip_id_behavior_innermost and ip_id_behavior_outer. For IPv6, only the ip_id_behavior_innermost field exists and its value is always IP_ID_BEHAVIOR_RANDOM according to the FN. This makes it impossible to include ip_id_behavior_outer when calculating the crc for IPv6 headers. Furthermore, since the ip_id_behavior_innermost is constant it makes no sense to include it in the crc calculation. 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. -------------------------------------- RFC5225 (draft-ietf-rohc-rfc3095bis-rohcv2-profiles-06) -------------------------------------- Title : RObust Header Compression Version 2 (ROHCv2): Profiles for RTP, UDP, IP, ESP and UDP-Lite Publication Date : April 2008 Author(s) : G.
