What is eBPF?

eBPF (extended Berkeley Packet Filter) is a revolutionary technology that allows sandboxed programs to run in the Linux kernel without changing kernel source code or loading kernel modules. It's commonly used for network monitoring, security observability, tracing, and performance analysis due to its ability to execute code at various tracepoints in the kernel and user space, enabling real-time insights into system behavior with minimal overhead.

What other technologies are related to eBPF?

eBPF Competitor Technologies

DPDK

DPDK (Data Plane Development Kit) is a set of libraries and drivers for fast packet processing in user space. While it provides high performance, it operates independently of the kernel's networking stack and thus competes with eBPF+XDP for similar use cases.

VPP

Vector Packet Processing (VPP) is a high-performance, user-space networking stack. It offers an alternative to kernel-based networking with eBPF.

iptables

iptables is a traditional firewall utility in Linux. While nftables is the official replacement, both are largely superseded by eBPF, which offers higher performance and flexibility for packet filtering and manipulation.

eBPF Complementary Technologies

XDP

XDP (eXpress Data Path) is often used with eBPF to provide a fast path for packet processing at the network driver level, allowing eBPF programs to be attached directly to the network interface.
