Link that spans at least 30 miles,

r that connects population centers of at least 100,000

people,

r that is shared by at least 2 providers.

Long-haul link

Building a US Long-haul Fiber Map

1. Build an Initial Map using Internet Atlas Project
2. Checking the Initial Map for conduit sharing
3. Build an Augmented Map with no explicit geocoding
4. Validate the Augmented Map conduit sharing

East-origin to west- bound West-origin to east-bound

SLIDE 10

Top 10 ISPs in terms of number of conduits carrying probe traffic

06.07.2017 Seminar - Internet Measurement 10

Findings:

Level3 is most widely used

infrastructure

XO also considered tier-1 ISP

carries only 25% of the volume

SLIDE 11

Mitigating Risks

Utilizing existing

conduits

Carefully choose

ISPs to peer Metrics:

Path Inflation
Shared Risk

Reduction

Robustness suggestion infrastructure for 12 heavylinks

SLIDE 12

Increasing Network Robustness (I) – peering suggestions

Mitigating Risks

06.07.2017 Seminar - Internet Measurement 12

SLIDE 13

Increasing Network Robustness (II) – adding links to lower shared risk

Mitigating Risks

06.07.2017 Seminar - Internet Measurement 13

SLIDE 14

Reducing Propagation Delay between individual city pairs

Mitigating Risks

SLIDE 15

Map gives very quick and easy to understand overview
Concern for FCCs Title II classification
Based on the map future improvements to the network are

easy to see

Discussion

SLIDE 16

Further improve coverage of the long-haul map
Add Data from Metro networks
Continue link validation process
Focus on traffic an propagation delay
