PAM Paper: Unintended consequences: Effects of submarine cable deployment on Internet routing (https://www.caida.org/publications/papers/2020/unintended_consequences/)
Our methodology can be divided into 4 steps. Each of them corresponds to the first 4 directories of this repository:
- Step1-collect-candidate-paths-crossing-the-cable
- Step2-identify-router-IPs-on-both-sides
- Step3-search-for-comparable-historical-traceroutes
- Step4-annotate-collected-paths
We added in Step5-data-analysis the scripts used for data analysis
E.g. pip install --target=/usr/local/bin pyasn
- Wandio
- urllib2 (Python2) or urllib (Python3)
- IPy (https://pypi.org/project/IPy/)
- pyasn (https://pypi.org/project/pyasn/)
- dnspython (https://pypi.org/project/dnspython/)
- docopt (https://pypi.org/project/docopt/)
- pycountry-convert (https://pypi.org/project/pycountry-convert/)
This folder contains the scripts for 2 possible ways for achieving this goal (Method1-Use-Henya-and-Ark-VPs and Method2-Use-RIPE-Atlas-VPs). The first method can be used for Ark VPs, while the second can be used for RIPE Atlas probe.
To identify the router IP interfaces, you can run the script 1_identify_router_IPs_from_ITDK_data_v2.py. The links IPs are listed in Final_list_IPs_RA.txt, and Final_list_IPs_RB.txt
You can use the script 1_Finding_Consistent_AS_pairs_transiting_cable_operating_AS.py to find consistent AS pairs transiting the AS operating the cable, and 2_Computing_lengths_AS_paths_between_consistent_AS_pairs.py to compute the length of AS paths between the same AS, destination prefixes pre & post SACS.
Collected and analyzed traceroutes and other datasets generated during the analysis are available here: http://data.caida.org/datasets/supplement/2020-unintended-consequences/
