It is packet based. There is no connection concept in IP.

From the IP Command Reference:

	equalize: allow packet by packet randomization on multipath
	routes.

My understanding is, that for equalize to work, all lines must go to
the same point and that must not be the end point. Also, this same
point must implement the equalize very much the same way.

Not using equalize.

unless there is a routing cache which will hold the path.
