Towards knowledge-defined networking using in-band network telemetry

Abstract

As the number of connected devices in the network is growing rapidly, network management is becoming more complex. Closed-loop network management can be a solution to address the problem, and self-driving network concept is one of the most promising solution. To realize the self-driving network, Knowledge-Defined Networking (KDN), network telemetry and Software-Defined Networking (SDN) are essential parts. As a first step toward realizing self-driving network, in this paper, we propose an architecture for self-driving network and suggest its use cases. We also present network monitoring system implementation on SDN controller using INT, and discuss its limitations.
