Hi Farah,

This is a very good question, I am adding geni-users since this might be
of interest to the larger community, please make sure you maintain the
list in your responses.

Let me try and answer your questions in order.

> 1- What aggregate do support the 1Gbps connections.

To the best of my knowledge all sites support a shared 1Gbps connection.
The sites that support stitching are listed here:
http://groups.geni.net/geni/wiki/GeniNetworkStitchingSites

I would suggest that you avoid any site that starts with GPO or Utah
since these are dev racks.

> 2 - Can I use stitching to reserve the topology as to set the
stitching node with 1Gb links ?

Yes you can

> 3 - How can we reserve a 1Gb connection to run our experiment.

Since this is an experiment that will use the whole 1Gb you should
schedule it with GMOC, so that other people avoid using your resources
at the scheduled time. To do that you can use these instructions:
http://groups.geni.net/geni/wiki/HowTo/PreReserveGENIResources

In the list of AMs make sure you mention that you will use stitching
between your resources, so they should include any AMs involved.
You should cc he...@geni.net in your reservation so that we can make sure
that it gets addressed in a timely manner.

Please keep in mind that you will have to go through this step every
time you want to run any inter-aggregate experiment that uses stitches
with a bandwidth of more than 500Mbps. You can schedule multiple
timeslots with one email to GMOC if you want.

Please let us know if you have any questions or you need help,
Niky

Hi Niky, 

Thank you for your response.

I tried to follow the link to get to the GMOC, but from the GENI page I clicked on Meta Operation Center (GMOC) and what I got is "Page not found".

Could you please check that for me.

Thanks, 

Farah

Hi Farah,

I just fixed the link. It now goes to: http://globalnoc.iu.edu/gmoc/index.html

Let us know if you have any other issues,

Sarah

HI Sarah, 

I followed the link now and it is working fine. 

But my question is to schedule an experiment time and a reservation, do I need to send a sample email such as the one linseed in the http://groups.geni.net/geni/wiki/HowTo/PreReserveGENIResources to their support team at bmoc AT grnoc.iu.edu ?

Thanks, 

Farah

So there is another issue to consider; we do not allow the 1Gb link
to be oversubscribed, so if another slice (or slices) is using portions of
the 1Gb link (say, a number of 100Mb slices of it), then you will not
be able to allocate a 1Gb link. There will be some coordination required,
with other experimenters, who might possibly need to terminate their
slices.

Something to consider is that people rarely use the amount of bandwidth
they think they need, especially when you consider that these links to
other aggregates are high latency, and possibly lower bandwidth then what
you see at the edge (the rack).

Even so, best to get your ducks in a row, and test everything using a lower
bandwidth requirement, before you ask people to clear off for you. :-)

Yes.  That's exactly right.
