As telecommunications networks continue to evolve, the demand for flexible and efficient packet processing has become paramount. The extended Berkeley Packet Filter (eBPF) has proven to be a powerful and versatile tool, offering performant fast data paths within the Linux networking stack in the form of eXpress DataPath (XDP). This presentation aims to provide a brief introduction to eBPF with focus on its use in telco environments.
We will delve into the architecture and capabilities of eBPF — a novel technology providing an ability to execute custom programs within the kernel without sacrificing performance. Attendees will gain insights into how eBPF enables real-time packet analysis, filtering, and modification, all while maintaining the efficiency required by modern telecommunication networks. The presentation will explore use cases relevant to telecommunication environments, showcasing how eBPF empowers operators to efficiently monitor, secure, and optimize network traffic.
