                     Performance Measurement on LAG
                       draft-li-ippm-pm-on-lag-01

Abstract

   This document defines extensions to One-way Active Measurement
   Protocol (OWAMP), Two-way Active Measurement Protocol (TWAMP), and
   Simple Two-Way Active Measurement Protocol (STAMP) to implement
   performance measurement on every member link of a Link Aggregation
   Group (LAG).  With the measured metrics of each member links of a
   LAG, it enables operators to enforce performance metric based traffic
   steering policy among the member links.

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are to be interpreted as described in
   [RFC2119] [RFC8174] when, and only when, they appear in all capitals,
   as shown here.

1.  Problem Statement

   Link Aggregation Group (LAG), as defined in [IEEE802.1AX], provides
   mechanisms to combine multiple physical links into a single logical
   link.  This logical link provides higher bandwidth and better
   resiliency, because if one of the physical member links fails, the
