Case of a Google Fiber Home in Kansas City
Google Fiber Ticket: Account # xxxxxxxxxxxxx, phone call with customer:
Tested @ 2:38 PM 1/8/2015: 91/92 (HP)Tested @ 2:40 PM 1/8/2015: 87/91 (Asus)Tested @ 2:42 PM 1/8/2015: 90/86 (HP)Tested @ 2:44 PM 1/8/2015: 88/66 (Asus)
Checked Speed & Duplex settings of HP device. Changed to Full 1 GBPS setting. Tested @ 2:49 PM 1/8/2015: 91/92 MBPS (HP) Restarted HP b/c it appeared that Speed & Duplex settings didn't take effect. Tested @ 2:54 PM 1/8/2015: 94/92 MBPS (HP).
CX advised me that he has a 3rd party router installed in between the NB and his PC's. CX asked if this would cause issues. I educated CX that it would b/c some routers will limit speeds to 100 MBPS. I requested the CX bypass the 3rd party router and HW directly to the NB. Only the Asus device could be HW'd directly to the NB. The Asus device is not GIG capable, and would not provide best results.
40 Mbps performance on a 1 Gbps access network connection!!…

KC Home to 150.199.7.214 = 50 Mbps
MU to 150.199.7.214 = 350 Mbps OSU to 150.199.4.146 = 840 Mbps
MU to 150.199.4.146 = 347 Mbps
MU<->OSU = 360 MbpsMU<->KC = 12 Mbps

Advanced manufacturing design today requires iterative and collaborative work among multi-site engineering experts…
• Collect requirements• Reverse engineer
physical component (e.g., scans)
• Build CAD model for virtual component(s)
Model
• Collaborate with customer via conferences• Ship VMs back-and-forth
• Iterate and improve component (i.e., Parameters, Geometry)
Simulate• Apps for vertical
• E.g., PipeFlow, CarPredictor, EduApp
• Manufacture physical improvements
Delivery

Summary of supporting GENI Services for User Opt-in
• Last-mile networks are a challenge– High-speed connections (e.g., Google Fiber in Kansas City, OARnet & MDC in Dublin,
OH) are needed, but not enough…– Users “feel” network is always the problem!
• Getting a GENI Rack into a city data center/experiment slice was necessary– Challenges with hosting, networking and platform setup
• Significant collaboration needed between App developers, network operators and users for testing and ensuring peak performance
– Not easy to translate ‘High Bandwidth’ & ‘Low Latency’ user requirements to suitable Cloud resource configurations in GENI
• Virtualization complicates performance troubleshooting– Is it the application, network or virtualization?
• Issues such as cost of the App/Service become important to users
