The Host-Side Pipeline: eBPF vs. P4 for Internal Kernel Packet Processing

Enforcing advanced network routing policies inside host servers historically required running heavy, inefficient software daemons that severely degraded kernel networking speeds.
🚀 The Programmatic Alternative: Running eBPF programs inside the Linux kernel allows for high-performance packet manipulation, reading and writing SRv6 headers natively in software.
Why this represents a structural transformation for host networking:
⚡ Kernel-Level Execution: Bypasses standard, slow kernel networking paths, processing packets almost as fast as dedicated hardware interfaces.
🐧 Unified Protocol Extensions: Allows application servers to append custom SRv6 routing instructions to outbound packets before they hit the wire.
📐 Continuous Path Visibility: Provides end-to-end telemetry visibility from the application container straight through the physical network fabric.
Extend your intelligent, software-defined network routing policies straight into your server operating system kernels.
