Juniper
Inband Network Telemetry (INT) is a vendor-neutral network monitoring framework that provides per-hop granular data in the forwarding (data) plane. INT allows you to observe changes in flow patterns caused by 1)microbursts, 2)packet transmission delay, 3)latency per node, and 4)new ports in flow paths.
