Performance monitoring can be supported by [RFC6374] in the DetNet MPLS and [ITU.Y1731] in the TSN domains, respectively. Performance objectives for each domain should refer to metrics that additive or be defined for each domain separately. The following considerations are to be realized when using the tunneling model of OAM interworking between DetNet MPLS and TSN domains: - o Active OAM test packet MUST be mapped to the same TSN Stream ID as + * Active OAM test packet MUST be mapped to the same TSN Stream ID as the monitored DetNet flow. - o Active OAM test packets MUST be treated in the TSN domain based on + * Active OAM test packets MUST be treated in the TSN domain based on its S-label and CoS marking (TC field value). Note that the tunneling model of the OAM interworking requires that the remote peer of the E2E OAM domain supports the active OAM protocol selected on the ingress endpoint. For example, if BFD is used for proactive path continuity monitoring in the DetNet MPLS domain, a TSN endpoint of the DetNet service has also support BFD as defined in [RFC5885]. 5.2.
