In situ Operations, Administration, and Maintenance (IOAM) is used for recording and collecting operational and telemetry information. Specifically, IOAM allows telemetry data to be pushed into data packets while they traverse the network.

2024年2月26日 · IOAM（In-band Operation, Administration, and Maintenance，带内操作管理和维护）是一种网络测量和监控技术。 它通过实时、高速地对业务流量进行采样，并在采样数据内添加IOAM信息（Metadata元数据，包含设备ID、出入接口、时间戳等），然后主动将采样数据发送给分析器进行分析，实现对网络运行状态的实时感知和监控。 为什么需要IOAM？ IOAM系统有哪些组成？ IOAM是如何工作的？ 为什么需要IOAM？ 随着互联网业务和用户规模的不断增长， …

2021年12月20日 · Code Point Name Description Status Reference; 0x0000: default namespace (known to all IOAM nodes) See Section 4.3: permanent [RFC9197, Section 4.3]0x0001-0x7FFF: Reserved for Private Use

IOAM Direct Export (IOAM-DEX) is one of the IOAM Option types, in which the operational state and telemetry information are collected according to the specified profile and exported in a manner and format defined by a local policy.

In situ Operations, Administration, and Maintenance (IOAM) collects operational and telemetry information in the packet while the packet traverses a path between two points in the network. This document provides a framework for IOAM deployment and provides IOAM deployment considerations and guidance.

IOAM DEX is also referred as the postcard mode, in which each node directly exports the telemetry data using an independent packet (i.e., sends a postcard) while the user packets are unmodified. The disadvantage of the passport mode is that if a packet is dropped on the path, the IOAM data collected are also lost.

本文档引入了一种新的 IOAM 选项类型（表示为 IOAM-Option-Type），称为“IOAM 直接导出 (DEX) 选项类型”。 此选项类型用作直接导出或本地聚合 IOAM 数据的触发器，而无需推送到正在传输的数据包中。

2020年11月1日 · In-situ Operations, Administration, and Maintenance (Ioam) is currently under standardization at the Ietf. It allows for collecting telemetry and operational information along a path, within the data packet, as part of an existing (possibly additional) header.

In situ Operations, Administration, and Maintenance (IOAM) is used for recording and collecting operational and telemetry information. Specifically, IOAM allows telemetry data to be pushed into data packets while they traverse the network.

2024年2月27日 · IOAM, a network measurement and monitoring technology, enables devices to sample service traffic, add IOAM information, and send the data to an analyzer.
