Introduction to eBPF Qdisc and Use Cases

Explore the innovative world of eBPF queueing discipline (qdisc) in this 24-minute conference talk by Amery Hung from ByteDance. Delve into the design and implementation of this programmable packet scheduler, which offers developers greater flexibility compared to traditional scheduling primitives. Learn how eBPF qdisc simplifies the process of developing and deploying qdiscs by allowing implementation through eBPF, reducing complexity and eliminating the need for writing kernel modules from scratch. Discover the four new types of eBPF programs and kernel functions available for qdisc development. Follow along as the speaker demonstrates the process of writing a qdisc using eBPF and presents three practical use cases, showcasing the potential applications of this technology in packet scheduling and network management.
