2010-9-15 · The FreeBSD Foundation agreed to fund Kristof’s work on if_bridge through aCommunity Grant. Kristof provides a detailed technical review of his work in the May/June issue of the FreeBSD Journal. For our purposes here, suffice to say the current if_bridge implementation contends heavily on a single BRIDGE_LOCK mutex.
A FreeBSD system with two network interface cards can act as a bridge. The bridge works by learning the MAC layer addresses (Ethernet addresses) of the devices on each of its network interfaces. It forwards traffic between two networks only when its source and destination are on different networks. A FreeBSD system with two network interfaces is enough in order to act as a bridge. A bridge works by scanning the addresses of MAC level (Ethernet addresses) of the devices connected to each of its network interfaces and then forwarding the traffic between the two networks only if the source and the destination are on different segments. In FreeBSD, if_bridge (4) is a kernel module which is automatically loaded by ifconfig (8) when creating a bridge interface. It is also possible to compile the bridge in to the kernel by adding device if_bridge to a custom kernel configuration file.
