Abstract:
Existing UNIX kernels cannot easily deliver IP packets containing IP options to applications. To address this problem, we have defined and implemented a new protocol family called PFIPOPTION or the FreeBSD kernel. We have verified the implementation with some of the commonly used IP options. Measurements in kernel and user space showed that BSD socket I/O is the performance bottleneck.
