Path Tracing in SRv6 networks
Path Tracing provides a record of the packet path as a sequence of
interface ids. In addition, it provides a record of end-to-end
delay, per-hop delay, and load on each egress interface along the
packet delivery path.
Path Tracing allows to trace 14 hops with only a 40-bytes IPv6 Hop-
by-Hop extension header.
Path Tracing supports fine grained timestamp. It has been designed
for linerate hardware implementation in the base pipeline.
