Performance Measurement in Segment Routing Networks with
IPv6 Data Plane (SRv6)
draft-ali-spring-srv6-pm-01.txt
Abstract
RFC 6374 specifies protocol mechanisms to enable efficient and
accurate measurement of packet loss, one-way and two-way delay, as
well as related metrics such as delay variation and channel
throughput in MPLS networks. This document describes how these
mechanisms can be used for performance measurement of delay and loss
in Segment Routing with IPv6 data plane (SRv6) networks.
