2022-06-09 Network Engineering Team Meeting notes

Philip DeMar

Reminder: Work on your action items: International Communications (aka Long-Haul Networks)

Network activities schedule (subject to COVID19 impacts):

January - Continued work on  Rubin Observatory Network Verification Plan (including JIRA). 

February - Completed draft  Rubin Observatory Network Verification Plan (including JIRA).

March - Scheduled Rubin Observatory Networks Pre-Verification Review for May 18 - 19

April - Prepare for Rubin Observatory Networks Pre-Verification Review.  Submit LSST Change Request to update LSE-78 Rubin Observatory Network Design (including Chilean, International, and US networks), and related milestones in PMCS.   Complete LDM-732 Rubin Observatory Networks Pre-verification Baseline.

May - Complete FY19, FY20 NET Reports and Technical Document

June - Conduct and respond to actions from Rubin Observatory Networks Pre-Verification Review.  Meet with GlobalNOC re VNOC support.

July  - Pre-Ops Rehearsal 2 testing.

August - Ops Rehearsal 2/Pre-verification testing.

September - Cisco ACI review, Huawei analysis 

October - Start Verification Testing, LS restart, LS - SCL 40G upgrade. (hopefully) - 

November - Update Rubin Observatory Operations & Management Plan, USDF Selection, CP Restart, Network Contracts and SLAs.

December - Updates on G-NOC service progress, Brazil path (Huawei) options, planning for US Data Facility at SLAC

January - Updates on G-NOC service progress, Brazil path (Huawei) options, planning for US Data Facility at SLAC

February - Agreed to propose NSF to DOE include funding of VNOC and Huawei in the ops proposal / USDF continuing discussing footprints, power cooling. 

March - Keep 2x20GB through Chicago during Construction. End of Construction Aug-FY23, would need 2x100 to SLAC.

New processing facility in UK, some data that goes to Europe will go to UK (1/4), likely 75% of data will be processed in Europe so more data will come back, so the 2x10GB link will likely increase 7-7.5GB per year

USDF & NCSA - CC- IN2P3 network:

Mark: Pre-ops preparation deploying 100gb links. 

Richard: Meeting between in2p3, geant, renater .100gb between in2p3 and geant, some extra bw available but needs to be isolated from other science projects, in particular LHCONE. 

Fabio: working group set up to exercise Rucio-driven bulk data replication between the data facilities (USDF, FrDF and UKDF).

By topic
