Hello, There was some open-source work done that allowed generic 802.11 clients to roam around on a wireless network without breaking stateful/session-orientated connections. It was called Transparent Mobility, and there is code available on the SF site below. I believe it was actually put into practice at SOWN, but there doesn't appear to have been any additional recent activity on the project. Nonetheless it was an interesting way to solve the problem of not having built-in roaming capabilities in 802.11. The description:
--- About Transparent Mobile IP This project aims to provide IP mobility across multiple networks, ensuring that all active TCP sessions will be maintained upon migration. No client side software or alteration to IP stack is required. The network itself changes to provide connectivity. --- http://www.slyware.com/projects_tmip.shtml http://www.sown.org.uk/index.php/TransparentMobility http://sourceforge.net/projects/tmip At 03:32 PM 12/28/2005 -0500, you wrote: >Matt, > >Great point, that many forget. > >For the record, there were several unlicensed products that ahve been >marketed to mobility, such as Alvarion 900Mhz.
