Implementation of network telemetry system with P4 programming language

Abstract

A very important factor for the network to operate is monitoring. Inband Network Telemetry is a mechanism for monitoring Software Defined Networks providing fine-grained telemetry information with less overhead on the control plane because the monitoring takes place in the data plane (inband). In this thesis, we examine the P4 language and the Inband Network Telemetry and propose a simple network monitoring architecture to monitor the network state information, identify and avoid congestions and apply load balancing.
