Dear all, Reading draft-ietf-bmwg-ipflow-meth-09.txt, I realized that this draft defines two new terms: Active Timeout and Inactive Timeout. I was thinking: surely, we have defined those terms already in some IPFIX RFCs. Actually, I was unable to find any references.... Have I overlooked something? The only pointers I could find are in RFC5102 5.11.1. flowActiveTimeout Description: The number of seconds after which an active Flow is timed out anyway, even if there is still a continuous flow of packets. Abstract Data Type: unsigned16 ElementId: 36 Status: current Units: seconds 5.11.2. flowIdleTimeout Description: A Flow is considered to be timed out if no packets belonging to the Flow have been observed for the number of seconds specified by this field. Abstract Data Type: unsigned16 ElementId: 37 Status: current Units: seconds 5.11.3. flowEndReason Description: The reason for Flow termination. The range of values includes the following: 0x01: idle timeout The Flow was terminated because it was considered to be idle. 0x02: active timeout The Flow was terminated for reporting purposes while it was still active, for example, after the maximum lifetime of unreported Flows was reached. ... Here is one issue. Some documents refer to inactive timeout RFC5472, ipfixMeteringProcessCacheInactiveTimeout in http://tools.ietf.org/html/draft-ietf-ipfix-rfc5815bis-03 inactiveTimeout in http://tools.ietf.org/html/draft-ietf-ipfix-configuration-model-10 While some others refer to idle timeout RFC 5102, draft-ietf-bmwg-ipflow-meth-09 Any proposal to fix this problem? Regards, Benoit (OPS A.D.)
