On Bandwidth (Jul 08 2009)

On a related note, would it be useful to get NASA or ESA involved in distributing radio telescope data?

As mentioned previously, I believe it has already been mentioned that the SSL are already using grey fibre, but only at 100 Mb/s.

If you can find that anywhere, I'd be interested. I think the current wire is copper.

[i]In reality, we have a 1GBit connection to the world via Hurricane Electric, but alas this is constrained by a 100 Mbit fiber coming out of the lab down to campus - it will take some big $$$ to upgrade that, which may happen sooner or later (as it would not only benefit us).

I mentioned how we seem to have a 60Mbit ceiling...

... We have gigabit all over our server closet (more or less - some older servers are 100Mbit going into the 1Gbit switch).

If it is political, that there isn't better comms to the building, maybe we need to shame the 'powers that be' into action.
A few thousand e-mails from the us users might wake them up. Or ask the students to have a demonstration on our behalf.

I think if we want to have a "demonstration" it'd be best to mail in a $5 bill rather than try to "shame" the administration into spending more money on what is clearly an under-funded project flying under the radar.

The minimum donation the Berkeley system supports is 10 U.S. dollars. Mailing in a $5 bill would create a bureaucratic dilemma, that's the worst kind.

That $5 amount has been mentioned several times recently, it is certainly tempting to think in terms of how little each participant would need to contribute to make this a well-funded project. But the world seldom works as we would prefer, I'm just trying to keep the record straight so practicalities aren't forgotten.

$5 is a metaphor, I meant "donate."

I should know that when dealing with engineering-types that it is better to specify the amount to three decimal places.

Never decimal places, always significant digits! :)

Thanks to the team that keeps our crunchers fed with work. Here's my thought on the comment about turning downloads off. 1st Turn data recorders off, split the tapes that have just been filled with fresh data to save trashing data collected. Is the gigabit Internet connection a flat rate or is it a set rate per petabyte? from the Current Budget fall 2008 it says that to get a 1Gbit connection to the lab it will be $80000. I'm not sure if this is the connection that the lab can only use 100Mbit of.

SETI buys their bandwidth delivered to one of the internet exchanges (PAIX) so it is very inexpensive.

Campus takes care of delivering it from PAIX to SSL. The university-owned connection isn't gigabit all the way from PAIX to SSL.

Bandwidth is available second-by-second, 24 hours/day. Turning off uploads and downloads, or limiting them to certain days, is just wasting every second during those days.

This is worth reading: http://www.mail-archive.com/setiathome@klx.com/msg01049.html

Some things have changed, like replacing Cogent with Hurricane Electric (at a lower cost), but the concept is still there.

Note that your first link is for off-campus service, provided by Comcast cable, and the Space Sciences Lab is on-campus.

Service to provide fiber connectivity to a department building that is outside of the main campus perimeter.

SSL is outside the main campus perimeter. Check the campus map.

This makes the $80,000 figure in the budget make sense.

This is provided by Comcast on a case-by-case basis, depending on their ability to provide fiber in the vicinity of the building. If fiber is available, the cost will vary depending on the amount of construction (e.g. trenching, provisioning for conduit) required to get the fiber into the building.
