6.  IANA Considerations

6.1.  Performance Metrics

   IANA has add four new performance metrics in the "Performance Metrics
   Registry" [RFC8911] with the four templates defined in Section 3.

6.2.  IPFIX Entities

   IANA has registered new IPFIX IEs (see Table 3) in the "IPFIX
   Information Elements" registry in the "IP Flow Information Export
   (IPFIX) Entities" registry group [IANA-IPFIX] and assigned the
   following code points.

                      Information Elements" Registry

6.2.1.  pathDelayMeanDeltaMicroseconds

   Name:  pathDelayMeanDeltaMicroseconds

   ElementID:  530

   Description:  This Information Element identifies the mean path delay
      of all packets in the Flow, in microseconds, between an OAM header
      encapsulating node and the local node with the OAM domain (either
      an OAM header transit node or an OAM header decapsulating node),
      according to OWDelay_HybridType1_IP_RFC9951_Seconds_Mean in the
      IANA "Performance Metrics Registry".

   Abstract Data Type:  unsigned32

   Data Type Semantics:  deltaCounter

   Reference:  RFC 9951

   Additional Information:  OWDelay_HybridType1_IP_RFC9951_Seconds_Mean
      in the IANA "Performance Metrics Registry".

6.2.2.  pathDelayMinDeltaMicroseconds

   Name:  pathDelayMinDeltaMicroseconds

   ElementID:  531

   Description:  This Information Element identifies the lowest path
      delay of all packets in the Flow, in microseconds, between an OAM
      header encapsulating node and the local node with the OAM domain
      (either an OAM header transit node or an OAM header decapsulating
      node), according to the OWDelay_HybridType1_IP_RFC9951_Seconds_Min
      in the IANA "Performance Metrics Registry".

   Abstract Data Type:  unsigned32

   Data Type Semantics:  deltaCounter

   Reference:  RFC 9951

   Additional Information:  OWDelay_HybridType1_IP_RFC9951_Seconds_Min
      in the IANA "Performance Metrics Registry".

6.2.3.  pathDelayMaxDeltaMicroseconds

   Name:  pathDelayMaxDeltaMicroseconds

   ElementID:  532

   Description:  This Information Element identifies the highest path
      delay of all packets in the Flow, in microseconds, between an OAM
      header encapsulating node and the local node with the OAM domain
      (either an OAM header transit node or an OAM header decapsulating
      node), according to OWDelay_HybridType1_IP_RFC9951_Seconds_Max in
      the IANA "Performance Metrics Registry".

   Abstract Data Type:  unsigned32

   Data Type Semantics:  deltaCounter

   Reference:  RFC 9951

   Additional Information:  OWDelay_HybridType1_IP_RFC9951_Seconds_Max
      in the IANA "Performance Metrics Registry".

6.2.4.  pathDelaySumDeltaMicroseconds

   Name:  pathDelaySumDeltaMicroseconds

   ElementID:  533

   Description:  This Information Element identifies the sum of the path
      delay of all packets in the Flow, in microseconds, between an OAM
      header encapsulating node and the local node with the OAM domain
      (either an OAM header transit node or an OAM header decapsulating
      node), according to OWDelay_HybridType1_IP_RFC9951_Seconds_Sum in
      the IANA "Performance Metrics Registry".

   Abstract Data Type:  unsigned64

   Data Type Semantics:  deltaCounter

   Reference:  RFC 9951

   Additional Information:  OWDelay_HybridType1_IP_RFC9951_Seconds_Sum
      in the IANA "Performance Metrics Registry".
