Subscription to Multiple Stream Originators
draft-zhou-netconf-multi-stream-originators-00
Abstract
This document describes the distributed data collection mechanism
that allows multiple data streams to be managed using a single
subscription. Specifically, multiple data streams are pushed
directly to the collector without passing through a broker for
internal consolidation.
Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
Status of This Memo
This Internet-Draft is submitted in full conformance with the
provisions of BCP 78 and BCP 79.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF). Note that other groups may also distribute
working documents as Internet-Drafts. The list of current Internet-
Drafts is at https://datatracker.ietf.org/drafts/current/.
Internet-Drafts are draft documents valid for a maximum of six months

1. Introduction
Streaming telemetry refers to sending a continuous stream of
operational data from a device to a remote receiver. This provides
an ability to monitor a network from remote and to provide network
analytics. Devices generate telemetry data and push that data to a
collector for further analysis. By streaming the data, much better
performance, finer-grained sampling, monitoring accuracy, and
bandwidth utilization can be achieved than with polling-based
alternatives.
