Solutions are described herein that provide for one-way end-to-end path delay measurements for Segment Routing (SR) and SR with IPv6 (SRv6) Traffic Engineering (TE) policies without clock synchronization in Software Defined Networks (SDNs). A centralized solution is provided using a controller while a distributed solution is provided without using a controller.
