Dynamic Link Exchange Protocol Traffic Classification Data Item
RFC 9892, “Dynamic Link Exchange Protocol Traffic Classification Data Item”, is a Proposed Standard document published in January 2026 by B. Cheng, D. Wiggins, L. Berger, D. Fedyk. The canonical text is published by the RFC Editor.
Abstract
This document defines a new Data Item for the Dynamic Link Exchange Protocol (DLEP) to support traffic classification. Traffic classification information identifies traffic flows based on frame/packet content such as a destination address. The Data Item is defined in an extensible and reusable fashion. Its use will be mandated in other documents defining specific DLEP extensions. This document also introduces DLEP Sub-Data Items and defines two new Sub-Data Items to support Diffserv and Ethernet traffic classification.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
