NET Action Items Status
Reminder: Work on your action items: International Communications (aka Long-Haul Networks)
Documentation updates schedule:
August - LSST Joint NSF/DOE Status Review will establish new overall project schedule, commissioning milestones. Observing with ComCam pushed back and shortened, observing with FullCam pushed back. We updated Network Milestones sheet accordingly. COMPLETE (See attachment)
September - working on LSST Change Request to update LSE-309 Summit - Base ITC Design Document (including Summit and Base networks) and related milestones in PMCS. Also creating FY20 contract amendments for FIU, REUNA, NCSA.
October - LSST Change Request to update LSE-78 LSST Observatory Network Design (including Chilean, International, and US networks) and related milestones in PMCS. Need updated diagrams, including ESnet, etc.
Jeff Kantor We will start to include NCSA - CC-IN2P3 information as it will need to be implemented by ANA circuits, participate in VNOC, etc.
Matt Kollross Raw Image Data will go every day to CC-IN2P3 for purposes of having 3 copies of data (for disaster recovery), processing does not require this fast (since CC-IN2P3 will not do Prompt/Alert Processing). Computing is based on NCSA and CC-IN2P3 each processing half of data for Data Releases. There will not be any connection between processing at NCSA and processing at CC-IN2P3
November - Develop complete LSST Network Verification Plan (including JIRA). See discussion below.
December - Develop draft LSST Operations Network SLAs. See discussion below.
|Update on CONUS Networks|
CONUS Networks, including ESnet:
LSST Continental US Networks Implementation Team (CNIT), sub team of LSST NET
Scope: All Florida - Illinois connectivity
Paul Wefel (Team lead), Kate Robinson, Gizella Kapus - ESnet
Jeronimo Bezerra - FIU/AmLight
Matt Kollross - NCSA
John Hicks - internet2 (tertiary path and Miami - Atlanta link until operations)
Julio Ibarra - FIU/AmLight
Kate Mace, Inder Monga - ESnet
Jeff Kantor - LSST
Wil O'Mullane - LSST
Phil DeMar - LSST Network Operations/FNAL
Paul Wefel We are currently working to bridge gap from LSST to ESnet in Atlanta.
Jeronimo Bezerra From Jacksonville to Atlanta use AL2S (good for FY20). Fiber between Boca and Atlanta goal is to be in place by September 2020, talking to provides. ACTION ITEM
|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:
Albert Astudillo Working with service provider, will have 40 Gb LS - Santiago in October. Equipment already on hand. Will have VLANs to support automatic fail-over. Prefer to use 100G interface to AmLight.
Jeronimo Bezerra We currently have 2 VLANs with 10G connectivity between Santiago and Miami (path diverse). Using 1 VLAN to Chicago. LS - Santiago currently 10G, upgrade to 100G in October. Will use 100G LR4 transceivers on both sides with LS - SCL.
Draft sent out in email, need input, comments from NET. Targeting end of August to complete. Jeff Kantordid first revisions and turned into google doc. Julio IbarraNow has lead on gathering comments, inputs from all others.
(We will also decide on boundary between this document and LSE-78, and how to manage documents for future updates.)
Debrief on TICAL Conference/LSST Workshop -
TICAL: Jeff Kantor presented talk (previously circulated)
Albert Astudillo Liked tools demonstrated by Ed Moynihan.
Ed Moynihan - Demonstrated NetSage, potentially valuable to LSST. Not real-time, but useful for analysis of historical data. Under development, based on Grafana.
Vincenzo Capone GEANT - Updating document shortly with results. Now understand each other's current situation and requirements. Focused on transatlantic path. Already understand in US and France. Main new understanding is that the procurement/provisioning of the transatlantic path will be somewhat more formal approval, but fits within "business as usual" model for ANA, GEANT. Currently 4 x 100 Gb path diverse fibers, Japanese procuring a 5th soon. ESnet also has 4 x 100 GB links and ESnet and ANA have mutual backup agreement.
Laurent Gyde RENATER - We currently have 2 x 10 Gb dedicated bandwidth for LSST Paris - Lyon, can go to 40G in 2020, will be at 100G in 2021-22. We are able to connect to GEANT in Paris and Geneva.
LSST Network Verification:
We are now approaching time when LSST Networks will need 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, etc. on LSST-NET home page.
Need to formally capture in JIRA, set schedules, etc.
LSST Network SLAs for Operations:
Jeff Kantor to start putting in place, work with Robert Blum, Director for LSST Operations. We know these will not be typical commercial (e.g. financial penalties) but we need to set expectations and resource levels.
This will be included in SLAs. Discussed in workshop. Indiana University potential to be involved. Ed Moynihan will connect with Global NOC and IRNC people who do this sort of work, connect with Jeff Kantorand eventually entire LSST NET.
|Network Design and End-to-End Test Plan and QoS planning||Need to finish 100G migration in Chile to resume work on this.|
|Monet Spectrum update||Now have 200G wave (2 x 100, 1 of them dedicated to LSST). Sao Paolo - Boca Raton - Miami. Working to extend Sao Paolo - Santiago, 2 x 100G waves, (1 for LSST, other shared). Co-location in ATL next year, we will connect 100G wave all the way (Primary path)|
Jeff Kantor LSST Operations funding is a separate award and agreement. NSF has to approve Ops proposal.
