	I knoo the possibility of DNS attacks was floated in the past,,,,,,but was discounted at the time.........might another new analysis of network traffic be in order at this time? I was curious about the traffic too, as I've been studying some networking subjects lately. When I started traffic was at a much more humble rate around 20Mbps on the cricket graphs. Switching to the long term view recently, however, seems to tell the grim truth: bandwidth utilisation is scaling proportionally with Moore's law... Hi Mark and Jason, not too much trouble in gettin WU's, UP- or DOWNloaded, only goes in big 'chunks', like 20 to 40 WU's at a time. On all hosts, 'large' numbers off waitin to UPload. But never mind that. Eventually, they get UPloaded. {EDIT/ADD}We don't have to panic, though ;) ____________ Knight Who Says Ni N!, OUT numbered.................

	But is it all due to crunching, or server data transfer, or what?????? Well surely some peak periods would represent recovery, and /or bulk moving server data about, however the general trend, and I'm looking at the yearly cricket graph here, looks somewhere between linear and exponential growth, and has gone from ~20Mbps to 60Mbps+ [in about a year?]. Assuming from the hardware donations threads that upgrading internal network speeds is going to happen gradually, that still leaves that 100Mbps link 'up the hill'. If that connection is fibre of some sort, replacing the transceivers at either end I reckon would cost big bucks :(. I hope we'll be alright for a while longer before that capacity is required, but then look at the general hardware performance increases of the last few years, seem pretty staggering, and set to continue. ____________ "It is not the strongest of the species that survives, nor the most intelligent that survives.

I hope we'll be alright for a while longer before that capacity is required, but then look at the general hardware performance increases of the last few years, seem pretty staggering, and set to continue. One of Eric's posts estimated the upgrade cost at over 30K USD, definitely not pocket change. As to the blip, I've noticed it at recurring periods on the Cricket graph. That is, the traffic in to SSL jumps up to about 12 MBits/sec at intervals of about 3 hours and remains high for about half an hour. If I try to upload or get new work during those high periods, there are a lot of HTTP 500 errors (Internal server error) and occasionally 503 or even 403. When the rate is below 10 MBits/sec those errors are fairly rare. I think the 90+ MBits/sec output rates recently are mostly the project uploading raw data to the NERSC HPSS at LBNL. There were a couple of periods when the project was down but there was still a steady ~35 MBits/sec flowing out, that would be the max rate of that flow though Matt said it was NICE'd so probably doesn't get that much when WUs are also being downloaded. Still, those blips at ~3 hour intervals are suspiciously close to how long it takes to upload 50 GB at 35 MBits/sec. Joe

	Coffee applied. It was actually the file upload handlers whining, I think. I moved them all back to bruno (where they are working fine) - up until just now half of them were going to anakin (for redundancy purposes), but for some reason anakin started barfing on them. - Matt ____________ -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

	I think it's fascinating that 22mr08aa still has the same two active channels as it had three weeks ago on 11 September, and 23mr08aa one. We've been remarkably lucky that the other splitters have had enough mid-range work to meet demand, thank the ALFALFA project for that. Joe
