RFC 3662: A Lower Effort Per-Domain Behavior (PDB) for Differentiated Services
This RFC has been replaced. Do not implement against it for new work — it was formally obsoleted by RFC 8622.
Current version: RFC 8622 — A Lower-Effort Per-Hop Behavior (LE PHB) for Differentiated Services
In plain English — editorial summary, not part of the RFC
This document proposes a differentiated services per-domain behavior (PDB) whose traffic may be "starved" (although starvation is not strictly required) in a properly functioning network. This is in contrast to the Internet's "best-effort" or "normal Internet traffic" model, where prolonged starvation indicates network problems. In this sense, the proposed PDB's traffic is forwarded with a "lower" priority than the normal "best-effort" Internet traffic, thus the PDB is called "Lower Effort" (LE). Use of this PDB permits a network operator to strictly limit the effect of its traffic on "best-effort"/"normal" or all other Internet traffic. This document gives some example uses, but does not propose constraining the PDB's use to any particular type of traffic.
