Rethinking the In-band Network Telemetry: Towards Application and Server-Level Network Telemetry
Francisco Germano Vogt, Fabricio Rodríguez, Marcelo Caggiani Luizelli, Christian Esteve Rothenberg · 2024
Fine-grained network telemetry is the basis for monitoring modern data centers and supporting in-network applications (INAs). INAs have recently adopted a new telemetry approach in which servers report data for INAs' use. Despite its potential, this method remains complex and unstandardized. This work introduces SATS, the Server and Application Telemetry System. SATS is the first effort to standardize application and server-level telemetry, offering high abstraction and easy deployment. SATS is a lightweight framework designed to enhance existing INAs' performance and encourage new ones' development.
