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.}, }
