Interesting. OK that makes sense. > Do you think ovs can handle these two interfaces? OVS doesn't have any special support for wireless. But it should support bridging wireless interfaces to the extent that they resemble Ethernet interfaces. Previously Jesse has stated that this probably won't be good enough though, see http://www.mail-archive.com/discuss@openvswitch.org/msg01128.html: ---------------------------------------------------------------------- On Fri, Jan 14, 2011 at 12:41 PM, Ben Pfaff <b...@nicira.com> wrote: > On Fri, Jan 14, 2011 at 09:44:47AM +0100, J?r?mie Tarot wrote: >> Before risking to go a dead end road, could someone tell me if Open >> vSwitch works with wireless interfaces and, if so, can these be part >> of a bond ? > > It should work, to the extent that wireless interfaces act like Ethernet > interfaces.

Wireless base stations generally only allow packets with the source MAC address of NIC that completed the initial handshake. Therefore, only a single device would be able to communicate and only over a single link unless you did some type of MAC rewriting. This isn't specific to Open vSwitch, it's enforced by the access point. ---------------------------------------------------------------------- > BTW, i have cross compiled the openvswitch_mod.ko module for Android by a > little trick: > > run configure without cross_compile, and then modify the Makefile in > datapath/linux-2.6 to add cross compile variables, and then run make in that > directory, and then i can get the cross compiled kernel module and it can be > installed on android. > > It seems ok, and this is a snapshot on my phone: > > <3>[105110.598785] init: sys_prop: permission denied uid:2000 > name:adb.connected > <4>[105178.558044] Open vSwitch 1.0.3, built Jan 24 2011 19:24:35 > # lsmod > openvswitch_mod 62905 0 - Live 0xbf211000 > tiwlan_drv 660205 0 - Live 0xbf14f000 > stp 1266 0 - Live 0xbf135000 > llc 3143 1 stp, Live 0xbf12e000 > # > > So i wonder how can test the module with the minimal cost? I'm not sure what you mean by "cost" here. ovs-openflowd would probably be sufficient for the simplest kind of testing. _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
