Greetings, I'm reposting an earlier reply to Matthew about an issue that I'm still puzzling over. I think Matthew may not have noticed my reply, and I think his original reply to my original post about dealing with asymmetric connections replicates a mistaken conclusion that I also made. If I'm off-track on all of this I apologize for wasting time, but I think there's a complication regarding the nature of ADSL that may lead to disappointing network performance.
<snip edited for brevity & better clarity> As I understand it, some requests arriving at my node are forwarded to other nodes, with the results being passed back through my node toward the original requester. If my inbound connecton is 2X, and my outbound connection is 1X, this means that data going _across_ my node can arrive at my node at twice the rate it can leave my node. If the results of data requests that cross my site can arrive at my site much faster than they can then leave on their way to their ultimate destination, it seems that I must _base_my_inbound_bandwidth_settings_strictly_on my_outbound_speed. Put another way, the trouble with relaying and ADSL is that since packets requesting data are presumably smaller than the resulting data packets coming back, it seems easily possible that a node will happily accept and forward many more request packets than it's truly capable of dealing with. If the results of request packets are larger than the request packets themselves, constipation will always result if the inbound bandwidth settings are not arranged strictly on outbound connection speed. Even more simply expressed, it seems to this ignorant user that if a node is capable of requesting data for relay far faster than it can actually pass it back through the network, chaos will surely be the result. Based on the assumption that the total bulk of request packets is smaller than total data packet bulk, it seems that ADSL users may in fact have to set incoming bandwidth _smaller_ than outgoing bandwidth, counterintuitive though this may seem. If all of this is true, maybe it would be a good idea to emphasize to ADSL node operators that they have to account for this in bandwidth settings. Further, is it possible to estimate based on data packet vs. request packet size some rough idea of what incoming vs outgoing bandwidth settings should be? -- "Americans generally do the right thing, after first exhausting all the available alternatives." - Winston Churchill _______________________________________________ support mailing list [EMAIL PROTECTED] http://hawk.freenetproject.org/cgi-bin/mailman/listinfo/support
