Hi All. After the "Explicit Flow Measurements" draft presentation (https://datatracker.ietf.org/doc/html/draft-mdt-ippm-explicit-flow-measurements-01) in the IPPM WG on March 12th, it was asked by Ian Sweet and Martin Duke if there are any implementations of the EFM methodology on servers and clients. Here is a list of some implementations made by the authors of the draft. TIM/Telecom Italia has realized an implementation for delay measurement with: - a client and a passive observer on mobile user devices, built in Android using Quic-Go (with gomobile binding) and spindump library. The observer executes delay measurements, both with Spin bit and Delay bit marking methods. The client app exchange QUIC traffic marked for Spin bit/Delay bit versus a server. - a server built by mean of Quic-Go, generates marked traffic and supports delay measurements with Spin bit and Delay bit methods. (Draft https://datatracker.ietf.org/doc/html/draft-cnbf-ippm-user-devices-explicit-monitoring-01) This implementation have been tested on TIM production network, both with mobile and fixed access. - Other implementations for loss algorithms (QR and T) have been tested in our lab with good results and we are planning to move them in production network for some services under our control. Akamai and Orange have built a monitoring system with QL marking, specifically for loss measurements. Their implementation has already been used in CDN servers to make EFM. Litespeed Tech also implemented QL marking in their lsquic library. Moreover, Ericsson is carrying out several monitoring initiatives using the SpinBit for delay EFM.
