           Test Protocol for One-way IP Capacity Measurement
             draft-morton-ippm-capacity-metric-protocol-00

Abstract

   This memo addresses the problem of protocol support for measuring
   Network Capacity metrics in RFC xxxx: draft-ietf-ippm-capacity-
   metric-method, where the method deploys a feedback channel from the
   receiver to control the sender's transmission rate in near-real-time.
   It supplies a simple protocol to perform the measurements.

   The authors seek feedback to determine what additional features will
   be necessary for an IETF Standards Track Protocol, beyond what is
   present in the running code available now.

1.  Introduction

   The IETF's efforts to define Network and Bulk Transport Capacity have
   been chartered and finally progressed after over twenty years.

   Over that time, the performance community has seen development of
   Informative definitions in [RFC3148] for Framework for Bulk Transport
   Capacity (BTC), RFC 5136 for Network Capacity and Maximum IP-layer
   Capacity, and the Experimental metric definitions and methods in
   [RFC8337], Model-Based Metrics for BTC.

   This memo looks at the problem of measuring Network Capacity metrics
   defined in [I-D.ietf-ippm-capacity-metric-method] where the method
   deploys a feedback channel from the receiver to control the sender's
   transmission rate in near-real-time.
