This document presents some observations on "simple best-effort"
traffic, defined loosely for the purposes of this document as
Internet traffic that is not covered by Quality of Service
mechanisms, congestion-based pricing, cost-based fairness, admissions
control, or the like. One observation is that simple best-effort
traffic serves a useful role in the Internet, and is worth keeping.
While differential treatment of traffic can clearly be useful, we
believe such mechanisms are useful as **adjuncts** to simple best-
effort traffic, not as **replacements** of simple best-effort
traffic. A second observation is that for simple best-effort
traffic, some form of rough flow rate fairness is a useful goal for
resource allocation, where "flow rate fairness" is defined by the
goal of equal flow rates for different flows over the same path.
