• 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.

• Improved openbach-functions:
  • Push file is now available to send files to the controller and from the controller to an entity.
  • New function allowing to reboot your agents on your desired kernel, even within a scenario.
• Improved auditorium_scripts:
  • An unified console output lets you clearly know wether the operation was successful or not.
  • 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.

• Big effort on openbach-extra and openbach-api:
  • New and more robust reference scenarios (network, transport, service, etc.) and executors to launch them from CLI.
  • New and improved jobs/helpers.
  • Polished auditorium-scripts.
• Reorganization of the wiki:
  • More understandable for new users (easy CLI and web interfaces manuals).
  • New conventions to standardize the way jobs/scenarios are developed.
• Improvements and corrections on post-processing, LDAP, platform update/backup and stability.
• New features, e.g.:
  • Allowed parallel job installation.
  • Improved admin web page for jobs: easier to install/uninstall/update jobs in your controller and agents.
• Other minor bugfixes and improvements.
