                     Loss and Delay Measurement in
          Transparent Interconnection of Lots of Links (TRILL)

Abstract

   Performance Monitoring (PM) is a key aspect of Operations,
   Administration, and Maintenance (OAM).  It allows network operators
   to verify the Service Level Agreement (SLA) provided to customers and
   to detect network anomalies.  This document specifies mechanisms for
   Loss Measurement and Delay Measurement in Transparent Interconnection
   of Lots of Links (TRILL) networks.
