But lets assume you have a router/gateway C in the wired network of your 2 gateways A, B. Then there are two possible routes: You -----(mesh)----> A ---> C You -----(mesh)----> B ---> C Only one of these routes is chosen, depending on which route looks better for the BATMAN algorithm in the moment of sending the packet.=20 So it always uses only the best route, but not both (as you can see,=20 it always chooses the "better gateway").=20 Using both routes simultaneously is an open research topic (look for=20 buzz-/keywords like "multipath routing"), but we have no working=20 implementation for this. In the best case its possible to gain more bandwidth, but this is only possible with multiple disjoint (interference-free) routes. Don't hesitate to ask more if i couldn't answer your question. regards, Simon [1] http://www.cs.huji.ac.il/labs/danss/sensor/adhoc/routing/lee_2001splitm= ultipath.pdf On Fri, Oct 24, 2008 at 03:43:07PM +0800, =E5=94=90=E9=BC=8E wrote: > hi > dose batman-adv support multi-gateway.=20 > If there is a router which connets two mesh devices(gateway) through sam= e layer 2 wired network, can the mesh network select a better gateway to th= e router for one packet.=20 >=20 > 2008-10-24=20 > _______________________________________________ > B.A.T.M.A.N mailing list > B.A.T.M.A.N@open-mesh.net > https://list.open-mesh.net/mm/listinfo/b.a.t.m.a.n --mYCpIKhGyMATD0i+ Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFJAbIqrzg/fFk7axYRAkASAJ9bH+r2bg6McjgRKDW1lorcPL0YQgCcD1/h 94BUhPkH8Y4Otz/+QieHsQA= =BT0+ -----END PGP SIGNATURE----- --mYCpIKhGyMATD0i+--
