  • New install options allowing to perform a full install of jobs (in controller and/or agents) or to check if enough resources are available to install OpenBACH [2]
  • New jobs allowing to deploy network mechanisms: RoHC header compression, VPN tunnelling (via OpenVPN and Wireguard), etc.
  • New jobs allowing to: perform emulation of level 2 retransmissions, MTU discovery, out of order packet detection, chat simulation, etc.
  • New executor references and examples [3]: a full OpenSAND example, a scenario allowing to compute Gilbert-Elliot parameters from pcaps losses, a VPN deployment, etc.
  • Improved/added features to existing jobs and scenarios (iperf3, web_browsing, etc.).
  • Mitigation of log4j vulnerability.
  • Minor bugfixes and improved overall performances (e.g. rstats).

We will be glad to get your feedback on our mailing list [4] and bug reports on the bugtrackers [5].

OpenBACH stable release 2.3.0

by OpenBACH team

Posted on Friday, 16 April 2021


Hi OpenBACH community,

The new release of OpenBACH is now supporting Ubuntu 20.04!

OpenBACH 2.3.0 includes the following evolutions:

  • Support of Ubuntu 20.04:
    • Controller/Collector/Auditorium and Agents support now Ubuntu 20.04.
    • All core jobs and external-stable jobs support now Ubuntu 20.04.
    • It is still possible to use/install OpenBACH on Ubuntu 16.04 if you git clone the tag openbach-2.2.0. However, the evolutions implemented on v2.3.0 (and newer versions) are not (will not be) available.
  • The web interface load has been reduced allowing to improve scalability:
    • The graphical analysis has been removed.
    • By default, the number of scenario instances that are loaded (for each scenario) is 10, and you can load more thanks to a Load button.
  • More documentation on openbach-api, command line usage and the validation suite.
  • New features and improvements, e.g.:
    • Improved validation suite.
    • New jobs have been added and obsolete jobs have been cleaned.
    • A new executor/scenario example named TCP evaluation suite is now ready to be used: its objective is to provide a complex scenario for evaluating TCP protocol performances under different network conditions.
  • Other minor bugfixes and improvements.

Hi OpenBACH community,

We are happy to announce a new release on our favourite network metrology testing tool: the new version 2.2.0!!

OpenBACH 2.2.0 includes the following evolutions:

  • Improved openbach-functions (bullets 1/2) and auditorium-scripts (bullets 3/4):
    1. Push file is now available to send files to the controller and from the controller to an entity.
    2. New function allowing to reboot your agents on your desired kernel, even within a scenario.
    3. An unified console output lets you clearly know whether the operation was successful or not.
    4. Added scripts to kill all jobs on any / all agents and to uninstall jobs before reinstalling a new version.
  • Improvements on jobs stability and installation process, as well as:
    • Reorganisation of jobs (from openbach-extra to openbach and viceversa).
    • Splitted tcpdump job: tcpdump_pcap (for traffic captures) and pcap_postprocessing (computes different statistics from a pcap).
    • Evolutions on apache2 (e.g. it includes now dash streaming content and new web sites).
    • New jobs: synchronization (force ntp), ftp_clt/srv, tc_qdisc_stats (monitor tc queues status) and more postprocessing jobs (temporal_binning_histogram and temporal_binning_statistics).
    • etc.
  • More accurate reference scenarios and executors and:
    • New executor examples allowing to show the modularity of the reference scenarios.
    • Improved stability on all scenarios.
  • More documentation on openbach-api (especially on the scenario_builder and the data_access).
  • New features, e.g.:
    • Improved statistics management and the possibility to disable local storage.
    • New validation suite module: allows to test the OpenBACH capabilities to prevent regressions and help develop new features.
  • Other minor bugfixes and improvements.
