Install VMTP: https://vmtp.readthedocs.io/en/latest/quickstart_pip.html

For the first time:

1, AZ setup of OpenStack 2, set VMTP conf file

VMTP version: 2.5.0

The process is the following: 1. Generate a resource topology 2. Generate service chain requests 3. Fingers crossed and start the simulation :)

Example command:

python3 topology_gen_random.py

Example command:

python3 request_gen.py -r topology.json

You need to use simulator.py python program. The resource topology, delay matrix and a requests json files must be generated previously.

For more information: python simulator.py -h

Example command:

python simulator.py -l test.log -r log/ostopo.json -dm log/delay_mtx.json -s log/requests/test2.json
