Title: Microscope metrics

Hi all and happy new year! Many thanks to James for keeping me on track with my task for our meeting on Thursday!!

Here is a brief network use summary of an event we held last spring where one of our K12’s connected to the electron microscope at our lab on campus at NDSU. At the same time, some of the students were located at our capitol building providing a demonstration to our governor and legislators on this tool. All sites are on our state gov’t/education network. The statistics should be self-explanatory – let me know if you have questions –

Averaging activity segments of approximately 5 minutes each, the connection was using 6.6 Mbps.

In support of bandwidth needs – this activity would obviously be difficult and slow over a T1 (1.5 Mbps) unless it would stream at a lower rate resulting in lower quality video.

Likewise, this will even fill a 10 Mbps rate which many schools in rural areas across the country have at this time.

In North Dakota, with so many of our schools running regular shared courses by videoconference, although bandwidth is not specifically dedicated to video, it is always pulled as first priority for videoconferencing leaving the remaining bandwidth for other activities, including connecting to a microscopy lab like this.

Talk to you all Thursday -
