| Update on CONUS Networks | CONUS Networks, including ESnet: 2 x 20 Gbps paths from Atlanta to Chicago built. Waiting for the AL2S portion to be built from Atlanta southwards. 2 options:
Received quote from internet2 for ports in Atlanta. High priority. Julio Ibarralead on this with internet2. Need to resolve co-location discussion, Jacksonville. | ||
| Chilean/International Networks Update | Developments in La Serena and end-to-end service to NCSA for upcoming Auxiliary Telescope Traffic and general (internet, mail, voice) traffic: LSST DWDM from Summit - Base upgraded with 2 x 100 G cards for general traffic. Moved a 20x10G card to different slot. DAQ over DWDM test completed successfully. DWDM service intervals and recent summit - caseta attenuation issue. REUNA usually just cleans filters. Fibers are usually okay as long as not touched, don't need frequent service. Attenuation issue happened maybe because equipment sat in storage for a long time. But there were no alarms. Unknown User (rlambert), Albert AstudilloDue diligence follow up on this problem. REUNA DWDM from La Serena - Santiago 100G upgrade now planned for January. Jeronimo Bezerrawill come to LS after setting up in Santiago? ATS now planned to ship by Christmas, on-sky mid-January. We are ready for start of data transfers. | ||
| NCSA - CC-IN2Pe Networks update | Unknown User (kollross) | NCSA - CC- IN2P3 network: There are multiple options from Chicago - Europe, need to define which one and get necessary approvals in place (including "right to use" for LSST operations and VNOC participation). See attached ANA-RENATER diagram. Unknown User (kollross)working with IN2P3, RENATER, GEANT on default plan going via CANARIE - Amsterdam. What MOUs do we need in place? Is this addition to LSST - IN2P3 MOU? Do we need to pay CANARIE ($ or other) | |
| Other Discussion Topics | By topic | LSST Network Document Update: Julio IbarraJeff Kantor https://docs.google.com/document/d/1ZvpaHwIzHHMuqRXJEornIgQNH_8tP_EfiV6S1SzyonU/edit New version is ready as soon as we get input from network operators to respond to questions, review document. Identified members of NET need to complete this by one week before next month meeting ACTION ITEM LSST Network Verification: Jeff Kantor LSST Networks needs to be formally verified as ready for LSST System Integration and Commissioning. 2019-07-11 Meeting published a list of requirement to be verified and a diagram of the JIRA test artifacts that must be done. (NOTE: Confluence can't render the JIRA test artifacts attachment, but it is a valid JPG file. Download it to view it.) Also see Network Verification Plan and Matrix, recently updated, on LSST-NET home page (and attached to this meeting page). Management wants a network readiness review sometime in January/February, need to discuss timing and scope. Ideally, this would come close after implementation of the ESnet 2 x 20 GB capability. LSST Network SLAs for Operations: Jeff Kantor FIU SLA in work, will use as template for others.
