Meeting Notes
REUNA, Albert Astudillo
Current Implementation
- Fiber link route with no protection, at the moment.
- LSST is using AURA’s DWDM for Internet, email, Web, etc. access and other services.
- Aux Tel data will use AURA temporarily.
- 10G ports will connect from LS to SCL.
October Goal
- REUNA will deliver service to Century Link (CL) DC.
- Aluizio - 2x100G will be delivered to CLARA at the Silica DC. Dedicated 100G and shared 100G.
- REUNA has the next infrastructure to the Silica DC. Transponders need to be added to extend the LSST link to Silica.
- Question: who will be responsible for extending the network service to either CL or Silica? JB commented that it should RNP-CLARA.
- JK: (ACTION) diagrams from Albert and Ron need to be merged into one diagram.
- JB: focus on what components (transponders) LSST requires.
- Fibers from REUNA DWDM system to AmLight switch: REUNA will provide fibers.
- AmLight needs to provide transceivers.
- Matt: proposed definitions and glossary. Matt volunteered to lead this effort.
- JK: Diagrams shown by JB will be used to the documentation. NET is to use stencils used by JB based on draw.io.
- JK described three different context involving LSST and AURA. AURA used by AURA is not our job. LSST can only influence LSST used by LSST, LSST-AURA used by LSST.
- Dave Wheeler (DW): Asked about layers. JK: replied in the affirmative about layers.
- Aluizio Hazin
RNP, Aluizio
100G channel for LSST thru RNP network
- 3 different DWDM systems, back to back transponders.
LSST through RNP network: Equinix SP4 - POP-SP
- Juniper router purchased by RNP. Transceivers LR4 or CWDM-4?
- JB: need to purchase the same or compatible technology.
LSST through RNP network: Equinix SP4 - POP-SP
- See Diagram in presentation
POP-SP to POP-PR
- See presentation
POP-PR to POP-RS
- See presentation
Infrastructure for LSST outside RNP network (1)
- PA/RS - BA/AR (Bella-T Project)
- BA/AR - SCL
- No x-connects.
- Connection from Silica to CL.
- Patch cords?
- Status of LSST Network, Ron Lambert
Base to Summit Optical circuits - Ron Lambert
- LSST 40G secondary path does not connect to DWDM system. The 40G secondary path connects to a router and uses a Telefonica link.
- JK does not want performance of network to be constrained by taps used. Policy decision. Need to get network correct.
- When Com Cam comes on board, July 2020, JK wants to be in the 100G capacity transponders. $50K from now and next year, JK will find the funds.
- Price needed to move to 100G with transponders. JK will follow up with NCSA for cost of taps.
- JB: have to consider router, transponders and transceivers. Believes cost should not reach $100K.
- Will proceed with the rest of this meeting doing 100G.
- Phases:
- Aux Tel that starts later 2019. Will use AURA infrastructure initially.
- Oct 2019 will open up US links
- Real volume when Com Cam starts, early to mid 2020.
AURA La Serena - Ron Lambert
- Focusing only on bottom of diagram, i.e. LSST dedicated paths, not AURA shared paths.
- There will be 2 border routers for LSST.
July Transfer Path - Ron Lambert
- 50MB every 15 seconds
- Network design for Aux Tel.
LHN Transfer Path
- Oct. Start to use LSST border routers.
- AmLight has no Actions at this time.
- RL: How many vlans will LSST require? Currently using vlans to get to AMPATH.
AmLIght, Jeronimo
SP3 to MI3 - AMLIGHT - wet network
SP3 to SP4 - RNP and ANSP
Patch cords, switch, transceivers - ANSP
MI3 to MI1 - dark fiber - dry network
Goal is to activate 400G.
Next Steps: Going North
2019:
- Boca will be a photonic site.
2020/2021:
NCSA, Matt Kolross
ICCN
Optical protected waves is possible. Can support 200G and 400G waves in the future.
WAN Connections
ESnet 600 W. Chicago Level 3
MREN 710 N. Lakeshore Dr. - StarLight
- 100G connection to MREN Ciena
NPCF
Green is 40G. Red is 100G.
This is today.
Action: What is NPCF diagram going to look like when ESnet circuits come in.
JB: ESnet circuits will be new ports. By 2020 ESnet will provide physical ports, directly from the optical device.
Action: Depict what ESnet circuits will look like.
Action: Paul Wefel: diagram that shows connections into the NPCF diagram.
JB: ESnet will pay only for their side of the connection.
Action: Matt and Paul: Confirm what will the actual config look like inside W. Chicgao and 710 N. Lakeshore, in fy20 and fy21.
Need the interconnection config - connections between ESnet and NCSA.
Other
Futures
IN2P3
Baseline plan requires IN2P3 to provide at least 10G. Not documented in a signed agreement.
Diagrams from Sessions 1 and 2:
Action: Consolidate diagrams from each operator into a single physical network diagram. If there are details in a particular network, its representative to diagram the details in a separate diagram using the templates provided by Jeronimo.
Session 3: Logical Topology
Refer to By Oct 1, 2019 diagram in Jeronimo’s slides.
Diagram 1:
Diagram 2:
Refer to questions in diagram.
Diagram 3:
Clarify ! (single points of failure)
JK comment: Do not have to be fully redundant until last milestone on the milestone spreadsheet.
Session 3: Planning the logical topology
LSST and NCSA will manage end points
- BFD plus loopback BGP?
- Ron: pure Layer3.
Ron’s concern: so many vlans.
MK: imagining 2 vlans.
AA: today: 3 sets of vlans today from the AURA router to the AMPATH router.
JB: would be good to have 3 vlans e2e.
JB: Do we want predictability?
Who is preparing the IP plan for the receivers and forwarders?
Will IP blocks be public or private?
REcommendation: Stick to the plan.
Static vlans across two routers, and loopback BGP session between two routers.
Action: LHN IP Plan to be completed by Ron. Confirm plan with Luis Coral.
Outcome: Update table from the 2017 report.
Session 5 - Establishing LSST Virtual NOC, Jeff Kantor
VNOC Vision
Customer experience is a single network, not 5 networks.
.5 FTE network eng at FIU and REUNA. 1.0 FTE at NCSA and La Serena.
LSST Help Desk could be first PoC. Can generate a ticket.
LSST Help Desk should be able to interact with the VNOC.
How much can LSST burden the LSST HD?
Monitoring and alarming should be 24/7. What is the LSST engineer staffing support model?
SLA for LSST Ops has not yet been written.
Goal: Integrated view of the complete network status.
Action: Define a data schema of all the data object that’s required.
Weather map for LSST users to see health of the network.
Consolidate data. Identify trends.
Action: By end of 2019 fy a budgeted, costed, scheduled plan of steps and implementation of plan will run with a capability in place by 2021.
Actions:
- Identify the players. JK
- Identify a team of people for a template or draft SLA for each of the providers, envision what they will be.
- Team of people to develop use cases and workflows for support.
- Team of people to work on elements for the data to share among the networks.
3 FTE engineering total. Can we get 24x7x365 coverage?
All the operators have 24x7x365 NOCs.
Session 4: E2E Test Plan, Pescador
LSST E2E Test plan document.
Action To NCSA: Necessary to upgrade pS node operational system.
Test Specifications:
OWAMP
What is the packet size?
Bandwidth:
pS provides both passive and active measurements.
Tests must eventually use the available path between LS and NCSA.
I2 has a Performance Assurance Methodology. JB asked if I2 would share their methodology. John Hicks said yes.
Action: Andres Villalobos to talk to JB about NetSage.
Next Steps:
Goal is to have a few nodes for testing and troubleshooting.
GridFTP test is used by NRP and I2. Helpful to determine capabilities of DTN and to troubleshoot network.
Action: Demonstration session: Add to next monthly meeting.
Review milestone sheet
Action: Craft updates to LSE-78.
Should schedule the next F2F meeting within a year or 6 months.
Publish results.
