Project description
Keysight IxNetwork Open Traffic Generator
The Keysight IxNetwork implementation of the open-traffic-generator models.
To start contributing, please see contributing.md.
Getting Started
Install client package
python -m pip install --upgrade ixnetwork-open-traffic-generator
Start scripting
# for constructing traffic configuration
from abstract_open_traffic_generator import (
port, flow, config, control, result
)
# for making API calls
from ixnetwork_open_traffic_generator.ixnetworkapi import IxNetworkApi
# provide API server and port addresses

# each of 128 bytes at 10% of max line rate
