+ + + Routing Stack Update + + + + + Alexander + Chernikov + + melifaro@FreeBSD.org + + + + + Initial Proposal + + + +

The projects/routing Subversion branch is a + FreeBSD routing system rework aimed at providing performance, + scalability and the ability to add advanced features to the + routing stack.

+ +

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 rmlock(9)s for the output path, + which permits close-to-linear scaling.

+ +

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.
