This conference talk explores how to implement Quality of Service (QoS) in DPDK-based cloud native routers. Learn how Kiran KN and Shailender Sharma from Juniper Networks leverage DPDK APIs to provide comprehensive end-to-end QoS functionality including classification, policing, rewrite, scheduling, and shaping in software router environments. Discover a new scalable packet processing model for QoS packet scheduling that doesn't rely on hardware ASICs or NIC capabilities, making it ideal for cloud environments with software NICs. The presenters demonstrate how their approach creates a highly scalable, optimal, and flexible model for software QoS implementation, particularly valuable for use-cases like 5G front haul and mid haul applications.
