In certain networks, network-performance criteria (e.g., latency) are becoming as critical to data-path selection as other metrics. This document describes extensions to IS-IS Traffic Engineering (TE) Metric Extensions (RFC 8570). This draft provides the necessary IS- IS extensions about the link bit error ratio (LBER) that need to be used to describe network-performance.
