[Talk Proposal] What is NAPI and how it is used for better performance in network

[Souradeep Chakrabarti]

Topic:
What is NAPI and how it is used for better performance in network

Abstract:

As modern applications demand ever-greater network speeds and
low-latency communication, achieving high performance in network
packet processing has become crucial. NAPI a vital component within
the Linux networking stack, offers a sophisticated approach to
handling high-speed data packets efficiently. This talk will dive into
the core concepts behind NAPI, exploring how it manages interrupt
moderation, reduces CPU overhead, and increases throughput by
dynamically switching between interrupt-driven and polling modes.

This talk will discuss the basics of traditional network packet
handling and the challenges posed by high-frequency interrupts under
heavy network loads. Next, it will explore the architecture of NAPI,
explaining how its adaptive processing model helps to mitigate these
bottlenecks, improves scalability, and enhances network performance.
Through real-world examples attendees will gain insight into using
NAPI for their environments.
