¿µ¹®³»¿ë¿ä¾à Operations, Administration, and Maintenance (OAM) Tools are of primary importance for IP networks [RFC7276]. DetNet OAM should provide a toolset for fault detection, localization, and performance measurement. The standard¡¯s primary purpose is to detail the specific requirements of the OAM features recommended to maintain a deterministic/reliable network with its ability to respect the Service Level Objectives (SLO). Specifically, it investigates the requirements for a deterministic network, supporting critical flows.

It describes the Introduction and defines terminology in section 1. In section 2, it describes the Role of OAM in DetNet. It describes Operation In section 3, Administration in section 4, and Maintenance in section 5. Requirements on OAM for DetNet Forwarding Sub-layer and Requirements on OAM for DetNet Service Sub-layer are described in section 6. It describes IANA Considerations in section 7, Security Considerations in section 8, Privacy Considerations in section 9 and References are listed in section 10.

The standard lists the functional requirements toward OAM for DetNet domain. The list can further be used for gap analysis of available OAM tools to identify possible enhancements of existing or whether new OAM tools are required to support proactive and ondemand path monitoring and service validation.
