This repository contains the operational and administrative datasets used in the paper with the code to generate them.

Data

The administrative_lifetimes.csv file contains the dataset of administrative lives. Each row of this file contains::

• ASN: the Autonomous System Number.
• startdate: the start date of the ASN's administrative life.
• enddate: the end date of the ASN's administrative life.
• regDate: the registration date of the ASN's administrative life.
• status: the status of the resource. The possible statuses are: {available, allocated, reserved}.
• registry: The registry that the ASN has been assigned to. One of: {afrinic, apnic, arin, lacnic, ripencc}.

We also provide cleaned_datasets_rirs.tar.xz, a more "raw" version of the dataset obtained by processing the delegation files after applying our restoration methodology. This dataset is different from the previous one because it does not consider the RIRs policies. To produce the administrative_lifetimes.csv from this dataset you can run the scripts that apply the RIRs policies as described below.

Code

Steps to produce the administrative dataset

1. Extract the cleaned_datasets_rirs.tar.xz file that is inside the cleaned_resources folder.

tar -xvf cleaned_datasets_rirs.tar.xz

2. Run close_span_per_rir.py.

python3 close_span_per_rir.py

3. Run implement_policy.py.

python3 implement_policy.py

4. Run remove_inner_span.py.

python3 remove_inner_span.py

5. Run close_final_resource.py.

python3 close_final_resource.py

This code generates the final administrative lives dataset: administrative_lifetimes.csv.

Steps to produce the operational dataset

1. Run bgp_close_span.py

python3 bgp_close_span.py

This code takes as input the operational_lifetimes_raw.csv and produces the operational_lifetimes.csv operational dataset merging all the operational lives of the same ASN that are closer than 30 days.
