Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Date: Fri, 05 Dec 1997 22:49:46 -0800 From: Paul Traina Sender: owner-freebsd-hackers@FreeBSD.ORG X-Loop: FreeBSD.org Precedence: bulk Metricom STAR mode eliminates the connection oriented reliable protocol that metricom uses to make the radio look like a modem. The disadvantage is that data is no unreliably transmitted. The advantages are that if you have a reasonable TCP stack (or even Linux's) you can raise your effective througput to nearly the modem's throughput (which is 100kbps). Unfortunately, since metricom doesn't offer an IP via STAR mode service, you're stuck building your own private network. A bunch of folks at stanford did this a few years back, it was quite impressive. try http://www-cs.stanford.edu, search for Mosquitonet or Stuart Cheshire. FYI, someone pointed me at (wow!) a NetBSD STAR mode driver. That's close enough that I may just get it up and running some time I'm flying off on a plane somewhere.
