🌬️ Zeph

Tests Coverage PyPI

Zeph is a reinforcement learning based algorithm for selecting prefixes to probe based on previous measurements in order to maximize the number of nodes and links discovered. Zeph can be used on top of the Iris platform.

🚀 Quickstart

Zeph has a command line interface to configure and run the algorithm.

First, install the Zeph package:

pip install dioptra-zeph

Zeph takes as input a list of /24 (IPv4) or /64 (IPv6) prefixes:

# prefixes.txt
8.8.8.0/24
2001:4860:4860::/64

To start a measurement from scratch:

zeph prefixes.txt

To start from a previous measurement:

zeph prefixes.txt UUID

Zeph relies on iris-client and pych-client for communicating with Iris and ClickHouse. See their respective documentation to know how to specify the credentials.

✨ Generate prefix lists from BGP RIBs

You can create an exhaustive list of /24 prefixes from a BGP RIB dump:
