In the first talk, Ferenc Fejes, Péter Antal and Márton Kerekes first give an overview of the TSN landscape and then show performance results of the variety of the kernel approaches in relation to scheduling precision when timestamping is done in hardware or software either in the rx or tx direction. Jitter performance results are provided when the datapath is going via the Linux bridge, XDP or AF_XDP. More info: https://netdevconf.info/0x16/session.html?The-TSN-building-blocks-in-Linux
In the second talk Justin Iurman and Benoit Donnet introduce Cross-Layer Telemetry (CLT) a mechanism to combine in-band telemetry and Application Performance Management (APM, based on distributed tracing with OpenTelemetry) into a single monitoring tool providing a full network stack observability. The CLT implementation (both for kernel and user spaces) is discussed and evaluated based on a use case.
