CONUS Networks, including ESnet:

Paul W. reported that ESnet had done some preliminary planning on diverse paths between Atlanta and SLAC, and showed a figure of one potential configuration.  Current understanding is that implementation should be relatively straightforward.  Use of the ESnet trans-Atlantic links for the IN2P3 ↔ US Data Facility was also thought to not be an issue from a traffic load perspective.

Cristian S. reported that the ESnet links between Atlanta & StarLight would remain in place for now (through commissioning phase?).  Matt K. reported that NCSA remains funded through 10/2021 for construction/commissioning network activities.

Developments in La Serena and end-to-end service to NCSA for upcoming Auxiliary Telescope Traffic and general (internet, mail, voice) traffic:

Christian S. outlined the rough schedule for cameras reaching the summit:  commissioning camera in late Dec/Jan, and main camera in summer time frame.  Deployment of the main camera on the telescope will be significantly later.

Christian S. reported that approval had been given for the fiber needed for the diverse backup link between the Base and Santiago, but there now existed a facility issue which might necessitate removal of that fiber.  While the AURA backup link is still there, Jeff K suggested this issue should be escalated to upper management.

NCSA - CC- IN2P3 network:

Matt K. talked about a cost issue with movement of data from IN2P3 into the Google cloud deployment of the Interim Data Facility.  The data needs to be moved from IN2P3 to NCSA, and then on to Google Cloud to avoid additional costs.  

Richard HJ & Stuart M. are confident they have solutions for IN2P3 connectivity to the US Data Facilities, regardless of whether or where they might need to connect to ESnet for moving data to/from SLAC.

Jeff K. said traffic levels for IN2P3 ↔ US Data Facility data movement should initially be ~10Gb/s initially, and increase ~5Gb/s annually.

By topic

Rubin Observatory Network Verification:

Cristián Silva:  Cristian S. has assumed responsibility for completion of the network verification testing.  Work is in progress.  

Richard HJ volunteered to set up performance measurement testing with NSCA and/or SLAC, although this is not part of the formal LHN verification testing.

SAACC (virtual) is tentatively proposed for April 13-14; corresponding face-to-face NET meeting (also virtual...) tentatively proposed for April 15-16.  Since NET meeting will be virtual, the option to hold it at another time is on the table.  For now, the NET meeting remains tentatively for April 15-16.
