            Transparent Interconnection of Lots of Links (TRILL)
                   <draft-ietf-trill-loss-delay-03.txt>

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 TRILL networks.

Status of this Memo
