HAWK (Highly-efficient Automated Weapon Kit)

Our networks (data centers, service providers, enterprises) make foundation for the successful applications' delivery to customers. Therefore, they are critical infrastructure of the modern digital economics. As such, we need to have an extensive set of tools and processes, which would allow us to plan, model, build, optimise and troubleshoot networks. This is exactly the purpose of the Highly-efficient Automated Weapon Kit (HAWK). HAWK is a collection of tools to help you to build and operate the networks of any types (data centres, service providers and enterprises) at world-class level.

Available functionality

At the moment HAWK is being developed as a set of Python tools, which at some point may become something much bigger.

Tool name	File	Description
Analyzer	topology_analyzer.py	Visualisation of the network topology (LLDP, BFD, BGP, ISIS) and what-if analysis of the node outage

Management Interfaces

The tools is constantly developing, so the changes may be frequent. At the current moment, the following interfaces are supported:

• SSH (in asyncrhonous mode)
• GNMI (in synchronous mode)

Network Operating System

Name	Inventory identificator	Implementation
Cumulus Linux	cumulus-linux	Done
Arista EOS	arista-eos	In progress
Nokia SRLinux	nokia-srlinux	Planned

Credentials

You can use one of 3 approaches:

• Provide variables in environment (HAWK_USER for username at network functions, HAWK_PASS for password for network functions, NB_TOKEN for NetBox API access, NB_URL for NetBox URL).
• Provide credentials for NetBox in config.yaml and username/password in local inventory file.
• Provide all the credentials via cli.

Requirements

Python

Created and tested in Python 3.7 - 3.9

Used libraries

Watch requirements.txt

Usage

1. Modify the the configuration file: config.yaml. If you chose local inventory, modify the inventory.yaml file inside the inventory directory per your topology.
2. Install the modules from requirements.txt using pip.
3. Execute the correspondin HAWK tool per the table above (e.g., python topology_analyzer.py) .
4. Open in the output directory the relevant generated reports.
