Introduction

This repository implements a data-collection and data-exploitation mechanism Aquarius as a load balancer plugin in VPP. For the sake of reproducibility, software and data artifacts for performance evaluation are maintained in this repository.

Get Started

Pre-Configuration

Run python3 setup.py, which does the following things:

  • update the root directory in config/global_config.json to the directory of the cloned aquarius repository (replace the /home/yzy/aquarius);
  • clone the VPP repository in src/vpp/base;
  • update the physical_server_ip in config/global_config.json to the IP addresses of the actual server IP addresses in use;
  • update the vlan_if as the last network interface on the local machine
  • update the physical_server_ip in config/cluster/unittest-1.json to the local hostname

VM images

To prepare a VM original image, refer to the README file in data. To run all the experiments without issues, create a ssh-key on the host servers and copy the public key to the VMs so that commands can be executed from the host using ssh -t -t.

Run example

A simple example is created using a small network topology (1 client, 1 edge router, 1 load balancer, and 4 application servers) on a single machine. Simply follow the jupyter notebook in notebook/unittest. Make sure the configurations are well adapted to your own host machine. Also make sure that the host machine has at least 20 CPUs. Otherwise, the configuration can be modified in config/cluster/unittest-1.json. To reduce the amount of CPUs required, change the number of vcpu of each node in the json file.

Reproducibility

To reproduce the results in Aquarius paper, three notebooks are presented in notebook/reproduce. The dataset that are generated from the experiments are stored in data/reproduce. To run these experiments, 4 physical machines with 12 physcial cores (48 CPUs) each are required. MACROs in the notebook should be well adapted. For instance, VLAN should be configured across the actual inerfacesin use. An example of network topology is depicted below.

Multi-server Topology

Notes

Running the scripts, e.g. src/utils/testbed_utils.py, requires root access.
