Dynamic Link Exchange Protocol Credit-Based Flow Control Messages and Data Items
RFC 9893, “Dynamic Link Exchange Protocol Credit-Based Flow Control Messages and Data Items”, is a Proposed Standard document published in January 2026 by B. Cheng, D. Wiggins, S. Ratliff, L. Berger, E. Kinzie. The canonical text is published by the RFC Editor.
Abstract
This document defines new Dynamic Link Exchange Protocol (DLEP) Data Items that are used to support credit-based flow control. Credit window flow control is used to regulate when data may be sent to an associated virtual or physical queue. These Data Items are extensible and reusable.
This document also defines new messages that support credit window flow control.
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.
