Abstract: With the rapid development of Internet applications, diversified Quality of Service (QoS) has been required in packet routing to meet the demand of various types of applications. This paper presents an Intelligent QoS-aware Routing (IQoR) framework with the assistance of Deep Reinforcement Learning (DRL), which supports multi-class QoS provisioning for packet forwarding. The simulation results show that IQoR outperforms the widely-used benchmark routing algorithms by significantly reducing the average delay and jitter of packets.
