Hello, I'd like to try on some changes that I've made in our VoIP testbed for mobility support at the application layer. If the user requires support for seamless voice communication during active call sessions on the mobile UA, it is imperative that the wireless LAN setup should support roaming across subnets, i.e. the mobile host should obtain a different IP address if it reassociates itself with an Access Point (AP) in a different subnet. I'm quite newbie to the wireless support of FreeBSD. I've got in my hands a wireless card with a Prims2 chipset, that's the only card I can use at this moment.. I've searched a little bit in Google and I've found out a guy that have made a patch for the linux wlan driver (www.linux-wlan.org), in order to support "roaming across subnets". I've got a lot of questions :-) Where is it coded the wireless support on FreeBSD ? I'd like to use FreeBSD-4.9 if that is possible....Besides, do I need to try to apply the previous patch to support roaming ? Any pointer or suggestion will be useful, of course. The guy that has made the patch seems to hack the part that starts with: "case HFA384x_LINK_AP_CHANGE:", I've made a "grep -r LINK_AP_CHANGE" in "/usr/src" but I found nothing :-( Thanks you very much ! -- ****** JFRH ****** Prof: So the American government went to IBM to come up with a data encryption standard and they came up with ...
