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.
