| ¿µ¹®³»¿ë¿ä¾à | In-situ Operations, Administration, and Maintenance (IOAM) is a technology that collects operational and telemetry information within packets while they move between two points in a network. This document defines the data fields and associated data types used in IOAM. IOAM-Data-Fields can be encapsulated in various protocols, such as the Network Service Header (NSH), Segment Routing, Generic Network Virtualization Encapsulation (Geneve), and IPv6. Additionally, IOAM can be used to complement traditional Operations, Administration, and Maintenance (OAM) mechanisms based on ICMP or other types of probe packets. The term "in-situ OAM" was originally motivated by the use of OAM mechanisms that insert information into in-flight data packets, rather than relying on dedicated OAM packets. IOAM may therefore supplement existing mechanisms such as Ping or Traceroute.
This document is organized as follows: Section 1 provides an introduction. Section 2 defines conventions. Section 3 describes the scope, applicability, and assumptions. Section 4 defines IOAM data fields, types, and nodes. Section 5 covers IOAM timestamps. Section 6 describes IOAM data export. Section 7 specifies IANA considerations. Section 8 discusses security considerations. Section 9 addresses privacy considerations. Section 10 provides references. While the term "in-situ OAM" originally referred to mechanisms that add OAM-related information within packets, in this document it is used to define IOAM technology in a broader sense, which encompasses both "in-situ" mechanisms and mechanisms that may generate additional OAM-dedicated packets. |
