DATASET GENERATION
	The dataset is created using the tangled-anygility toolset. It contains Verfploeter measurement files, routing information (tangler-cli), and statistics of catchment distribution from Verfploter files (vp-cli).

Dataset Contents
Usenix_anygility_readme.txt - this readme file
Usenix_anygility_3_sites.tar.gz - catchment distribution with 3 sites (uk-lnd,fr-par,au-syd)
Usenix_anygility_5_sites.tar.gz - catchment distribution with 5 sites (uk-lnd,fr-par,au-syd,us-mia,us-los)
Usenix_anygility_7_sites.tar.gz - catchment distribution with 7 sites (uk-lnd,fr-par,au-syd,us-mia,us-los,br-poa,nl-ens)
Usenix_anygility_poison.tar.gz - experiment with poison routes em US-MIA.
Usenix_anygility_5_sites_2022-03-24_NEW.tar.gz - catchment distribution with positive and negative prepends in 5 sites (uk-lnd,fr-par,au-syd,us-mia,br-poa)

Each dataset of 3_sites, 5_sites, and 7_sites had ICMP requests generated in US-MIA includes:
- UNICAST test: just one node active 
- BASELINE: all set of nodes active and no specific routing configuration
- NEGATIVE PREPEND: experiment with 1 to 5 negative prepends on each site
- POSITIVE PREPEND: experiment with 1 to 5 prepends on each site
- COMMUNITY: Measurement using distinct BGP communities 

Each measurement contains five files:
- *.csv.gz : Verploter raw file
- *.meta : parameter used to run vp-cli to obtain statistics (stats)
- *.meta-convert : parameters to normalize files (this dataset does not contain normalized files)
- *.routing : anycast routing setup 
- *.stats : catchment distribution statistics


DATASET FORMAT 

FILENAME: 
	Each filename contains the routing policy used, active nodes, and timestamp.

VERFPLOTER FILES (*.csv.gz):
	Those files are in CVS files and were collected with Verfploter v0.1.42. Each file represents an entire measurement using the 2019-11-27 hitlist. Verfploter files are in the following format:

task_id: internal Verfploter information
client_id: anycast site where the packet was received
transmit_time: Packet generation timestamp 
receive_time: Packet received timestamp 
send_receive_time_diff: difference between transmit_time and receive_time
source_address: IP address of the ICMP Echo reply message sender
destination_address: anycast IP 
meta_source_address: ICMP echo request source IP (anycast address)
meta_destination_address: ICMP echo request destination IP
ttl: Time to live between source_address and destination_address
source_address_country: country geolocation data on measurement using maxmind database (GeoLite2-Country.mmdb)
source_address_asn: Autonomous system number obtained with maxmind database (GeoLite2-ASN.mmdb)
