Quick Start

The Terragraph Planner is an open-source Python library developed for operators to plan and optimize a mesh network using Terragraph's 60 GHz mmWave technology.

Download

git clone [email protected]:terragraph/terragraph-planner.git

or

git clone https://github.com/terragraph/terragraph-planner.git

Install

  1. Update the source, install pip3 and gdal lib. Use apt if you are using Ubuntu. Use another package tool instead if you are using different OS. 
    apt update && \
apt install -y software-properties-common && \
apt install -y python3-pip && \
apt install -y gdal-bin && \
apt install -y libgdal-dev && \
  2. Set up environment varibles for gdal lib. 
    export CPLUS_INCLUDE_PATH=/usr/include/gdal && \
export C_INCLUDE_PATH=/usr/include/gdal
  3. Change the directory to your local repository.
  4. Install the terragraph_planner package. 
    pip3 install .
  5. Install the extra recommended Python packages if you are a developer. 
    pip3 install -r requirements_dev.txt

Set up FICO Xpress

  1. Go through steps in Install to install xpress
  2. Set the environment variable XPAUTH_PATH to the full path of your commericial license if you have one. Otherwise, the community license is used by default (which will only work for very small plans).
  3. If you are using a commercial license for xpress, please specify the version of xpress and install it separately after step 4 in the last section. 
    pip3 install xpress==x.y.z
    where x.y.z is the version compatible with your license.

Get more details at FICO Xpress Optimization Help.

Run Tests

Run the tests to check if the package is correctly installed.

python3 -m unittest discover terragraph_planner -b

Using different versions of 3rd party dependencies from the ones specified in the requirements file can lead to test failure; this does NOT mean the optimized plan quality is degraded.

Run a Plan

Configuration File

One way to customize and run a plan is using an input configuration yaml file. Refer to template.yaml for available parameters. In general, any parameter not provided in the input configuration file will use the default value instead. With the exception of the file paths and list of devices, default values can be found in that yaml file.

Line-of-Sight Analysis Plan

A Line-of-Sight Analysis Plan only runs LOS checks and produces a candidate network without optimization.

To run an LOS Analysis Plan with a configuration file:

from terragraph_plannner import generate_candidate_topology_with_config_file

generate_candidate_topology_with_config_file(config_file_path)

Optimization Plan and End-to-End Plan

An Optimization Plan optimizes the input candidate network. An End-to-End Plan runs both the LOS analysis and the network optimization.

To run an Optimization Plan or End-to-End Plan with a configuration file:

from terragraph_plannner import optimize_and_report_topology_with_config_file

optimize_and_report_topology_with_config_file(config_file_path)

The configuration file will control which plan type is run. If the candidate topology file is provided, only the Optimization Plan will be run. If the candidate topology file is not provided, the End-to-End Plan will run.
