Real-Time Transport Object Delivery over Unidirectional Transport

Overview

RFC 9223, “Real-Time Transport Object Delivery over Unidirectional Transport”, is an Informational document published in April 2022 by W. Zia, T. Stockhammer, L. Chaponniere, G. Mandyam, M. Luby. The canonical text is published by the RFC Editor.

Abstract

The Real-time Transport Object delivery over Unidirectional Transport (ROUTE) protocol is specified for robust delivery of Application Objects, including Application Objects with real-time delivery constraints, to receivers over a unidirectional transport. Application Objects consist of data that has meaning to applications that use the ROUTE protocol for delivery of data to receivers; for example, it can be a file, a Dynamic Adaptive Streaming over HTTP (DASH) or HTTP Live Streaming (HLS) segment, a WAV audio clip, etc. The ROUTE protocol also supports low-latency streaming applications.

The ROUTE protocol is suitable for unicast, broadcast, and multicast transport. Therefore, it can be run over UDP/IP, including multicast IP. The ROUTE protocol can leverage the features of the underlying protocol layer, e.g., to provide security, it can leverage IP security protocols such as IPsec.

This document specifies the ROUTE protocol such that it could be used by a variety of services for delivery of Application Objects by specifying their own profiles of this protocol (e.g., by adding or constraining some features).

This is not an IETF specification and does not have IETF consensus.
