That task can be solved using on-path telemetry, also called hybrid measurement. An on-path telemetry method allows the collection of essential information that reflects the operational state and network performance experienced by the packet. This document introduces a method complementary to on-path telemetry that causes the generation of telemetry information. This method, referred to as Hybrid Two-Step (HTS), separates the act of measuring and/or calculating the performance metric from collecting and transporting network state. The HTS packet traverses the same set of nodes and links as the trigger packet, thus simplifying the correlation of informational elements originating on nodes traversed by the trigger packet.}, }
