+ <body>
+ <p>The <tt>projects/routing</tt> Subversion branch is a
+ FreeBSD routing system rework aimed at providing performance,
+ scalability and the ability to add advanced features to the
+ routing stack.</p>
+
+ <p>Currently, the packet output path suffers from excessive
+ locking, acquiring and releasing 4 distinct contested locks is
+ required in order to convert a packet to a frame suitable to put
+ on the wire. 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>
