Method for probing network paths in disaggregated scheduled fabrics and a system thereof

Abstract

Devices, networks, systems, methods, and processes for probing a network path in a Disaggregated Scheduled Fabric (DSF) are described herein. A source device, such as a first leaf switch can receive a probe command and identify a network path associated with the probe command. The first leaf switch may generate, based on the probe command, a probe packet comprising a fabric header. The first leaf switch can identify an adjacent device such as a spine switch and transmit the probe packet to the spine switch. The spine switch can forward the probe packet to a destination device, such as a second leaf switch. The second leaf switch may generate and transmit a response probe packet in response to the probe packet. The probe packet can be utilized to measure one or more Quality of Service (QOS) parameters such as jitter, latency, packet loss, or congestion etc. for example.
