Mark, Some points that I hope are not already clear but hopefully address a couple of points in your posting. Bridges build topology of the layer 2 (Ethernet) network based on listening to the MAC address connected to each port (or if cycles exist in the network using spanning tree protocol). So each bridge knows what MACs are on which port, by definition of how bridges work. So don't worry about packets going wrong direction - bridges know where the MAC is (the exception is if a bridge gets a packet and has not heard the MAC previously, then it "floods" the packet to all bridge ports). Also, ARP is running, so device IP stacks ARP the destination IP and get the MAC, before sending. When the device is "local" to the Ethernet (in the same subnet, wired or not - the contiguous bridged domain) the device stack knows not to use the router for packet forwarding. If a device is locally connected the packet goes direct. Finally, hops don't matter. Don't let anyone tell you they do. Most people who think hop counts are important are listening to old anti-IP FUD from ATM and TDM vendors of years gone by and IP stacks with low initial TTL from yesteryear. The simple fact is that the cut through time (time from first bit in to first bit out with no queueing delay) on a two port bridge (which is that the SB3 is) is measured in microseconds, If the silicon is less intelligent and buffers the whole packet, you are looking at milliseconds. It just doesn't matter. If you were going multiple times over the same wireless network, that would be an issue, but that is not what is happening in this example. -- Eric Carroll ------------------------------------------------------------------------ Eric Carroll's Profile: http://forums.slimdevices.com/member.php?userid=9293 View this thread: http://forums.slimdevices.com/showthread.php?t=31850 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
