ng_hub — packet
distribution netgraph node type
#include
<netgraph/ng_hub.h>
The hub node type provides a simple
mechanism for distributing packets over several links. Packets received on
any of the hooks are forwarded out the other hooks. Packets are not altered
in any way.
A hub node accepts any request to connect,
regardless of the hook name, as long as the name is unique.
This node type supports the generic control messages, plus the following:
NGM_HUB_SET_PERSISTENT
(setpersistent)This node shuts down upon receipt of a
NGM_SHUTDOWN control message, or when all hooks have
been disconnected. Setting the persistent flag via a
NGM_HUB_SET_PERSISTENT control message disables
automatic node shutdown when the last hook gets disconnected.
netgraph(4), ng_bridge(4), ng_ether(4), ng_one2many(4), ngctl(8), nghook(8)
The ng_hub node type appeared in
FreeBSD 5.3.
