Ultra Ethernet Transport

The Ultra Ethernet Consortium has a mission to Deliver an Ethernet based open, interoperable, high performance, full-communications stack architecture to meet the growing network demands of AI & HPC at scale. The recently released UE-Specification-1.0.1 includes an Ultra Ethernet Transport (UET) protocol with similar functionality to RDMA over Converged Ethernet (RoCEv2).

The sFlow instrumentation embedded as a standard feature of data center switch hardware from all leading vendors (Arista, Cisco, Dell, Juniper, NVIDIA, etc.) provides a cost effective solution for gaining visibility into UET traffic in large production AI / ML fabrics. 

docker run -p 8008:8008 -p 6343:6343/udp sflow/prometheus

The easiest way to get started is to use the pre-built sflow/prometheus Docker image to analyze the sFlow telemetry. The chart at the top of this page shows an up to the second view of UET operations using the included Flow Browser application, see Defining Flows for a list of available UET attributes. Getting Started describes how to set up the sFlow monitoring system.

Flow metrics with Prometheus and Grafana describes how collect custom network traffic flow metrics using the Prometheus time series database and include the metrics in Grafana dashboards. Use the Flow Browser to explore UET flow metrics and then configure a Prometheus scrape task to collect useful operational metrics.
