1 AURA Users Mtg: Networks
Mission to provide base to summits and international network connectivity for all tenants operating under the AURA umbrella, including other Institutions with specific MOUs, e.g. NRAO/ALMA, Carnegie/Las Campanas.
Prior to 2011/2012, the network services were of limited bandwidth, funded solely by NOAO and Gemini.
2 AURA Users Mtg: Networks
International links ◦ ~1985-1995: NASA satellite link from Tololo to
Ames, FL providing 56Kbps ◦ 1995-2000: Entel ISP providing 256Kbps,
increasing to 4Mbps ◦ 2005-present: REUNA+Ampath providing
50Mbps, then 155Mbps, and now 622Mbps Mountain Links ◦ 1985-2000: Collins Microwave 64Mbps ◦ 2000-present: Harris Microwave w/ dual
155Mbps, expandable to 624Mbps
3 AURA Users Mtg: Networks
Transition to robust high-speed network ◦ ~1Gbps total, shared ◦ Multiple paths to U.S. mainland
Supporting growing number of users ◦ Two fundamental classes: “low volume/basic connectivity” “high volume/mission critical”
Requires shared cost model to fund operations, maintenance, and upgrades
4 AURA Users Mtg: Networks
National Link: ~$150K/yr ◦ REUNA (Chilean equivalent of Internet2) ◦ Membership + 1Gbps
International Link: $200K/yr ◦ LAUREN+AmLight (NSF supported link) ◦ Currently 622Mbps, planned 1Gbps
O&M: $140K/yr ◦ including only 0.5FTE + hardware + training
5 AURA Users Mtg: Networks
“Basic Connectivity” ◦ Access to infrastructure (includes base of
operations & maintenance cost + 10Mbps) ◦ $10K/year
“High Volume / Mission Critical” ◦ Needing 10 – 100 Mbps for larger volume
data transfer, burstable to almost 1Gbps ◦ $75K/year
Not metered, but Monitored
6 AURA Users Mtg: Networks
1. Research traffic (.edu) 592Mbps
2. International Commodity traffic 30Mbps
3. National Commodity traffic 10Mbps
4. REUNA National Backbone 30Mbps
5. SOAR direct vlan to Brazil 10Mbps
6. Entel emergency link (pending) 20Mbps

LSST: massive data transfer requirements ◦ 100-200Gbps from mountain to base ◦ >15TB/night to U.S., possibly in real time!
LSST construction plans ◦ Fiber bundle connecting summits to base,
allowing 1Gbps to 100Gbps ◦ 40Gbps to 80Gbps international link
