CONUS Networks, including ESnet:

Debugging with Nokia ingress issue with VPLS buffer allocation in Atlanta, affects both sides.  Met to discuss 100G upgrade, using internet2, developing options to connect Marietta (FIU) and Peachtree (ESnet).  In FY22, dedicated Boca - Atlanta link will be in place, internet2 will only be backup.  Jeff Kantor updated network "cloud" diagrams in LSE-78 and Technical Document to show this.

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

Near term work to coordinate: IT-1762 (and placeholder SUMMIT-3917) - Plan for atarchiver/LATISS switch-over to LSST network (e.g. ungang atarchiver network ports), LSE-309 backbones/separation of traffic.  DM confirmed that Operations Rehearsal 2 (date TBD) will transfer LATISS data over LSST network.

Summit is shut-down, all operations moved to Base. ComCAM is being installed in Base Data Center. Servers were racked (should have been on summit, this is temporary). Network connections being set up; Brian Stalder working on configuring servers, etc.

Albert Astudillo says Telefonica are ready to install LS - SCL backup link.  Should have been ready by end of June, but pandemic will delay, probably July.  Meanwhile working with fiber between Telefonica LS and AURA LS.  No progress on negotiating down costs for increasing 40G to 100G.

NCSA - CC- IN2P3 network:

Jeff Kantor  Got data volume statistics from Kian-Tat Lim , described increase of data volume between NCSA and IN2P3 over time for DRP.

Need to be ready for LCR to LSE-78 and submit LCR to baseline this document prior to Pre-Verification Review, publish to review web site on May 1, 2020.  Finishing Tech Document:

• Change introduction to be a spec/baseline document, not a meeting report
  Change future tense to present tense, as currently configured
  Appendix? to indicate only known changes needed before FY22 start of operations
  Future demonstrations sections change orientation to ongoing maintenance/testing
