The first project goal is to reduce the number of + locks needed to just two <tt>rmlock(9)</tt>s for the output path, + which permits close-to-linear scaling.</p> + + <p>Since September, one of the locks (used to protect + link-level entries) is completely eliminated from the packet data + path. A new routing API was introduced, featuring better + scalability and hiding routing internals. Most of the consumers + of the old routing API were converted to use the new API.</p> + </body> + </project> </report>
