OpenSAND new release 6.1.0

by OpenSAND team

Posted on Wednesday, 14 December 2022

Hi OpenSAND community,

We are happy to announce the new release 6.1.0 of the OpenSAND satellite emulator before Christmas!

This new version includes the following updates:

  • Added support for ubuntu 22.04 (jammy).
  • The satellite can work again on regenerative mode. We have recovered the regenerative satellite (at different levels) with a new design and a modular approach. The satellite can now work on transparent mode, on IP-regenerative mode and on BBFRAME-regenerative mode.
  • OpenSAND has evolved to allow for a satellite constellation (up to two satellites, as of now) and an emulated Inter-satellite Link (ISL) with a variable delay between the satellites.

The documentation of the new functionalities is available here

In addition to the standard way to use OpenSAND, remember that you can use an example of an OpenSAND deployment to be executed by means of the test bench OpenBACH [1]. This example is available in openbach-extra, and you need to previously install OpenBACH and openbach-extra [2].

We will be glad to get your feedback on our mailing list [3] and bug reports on the bugtracker [4].

OpenSAND new release 6.0.0

by OpenSAND team

Posted on Thursday, 14 April 2022

Hi OpenSAND community,

We are excited to make two major announcements:

  • OpenSAND has moved to GitHub! [1]
  • The new release OpenSAND 6.0.0 is now available with a dedicated web interface!

This version brings in the following changes:

  • A new web interface that replaces the manager and that allows to:
    • Create the OpenSAND configuration.
    • Deploy the configuration and start/stop the OpenSAND binaries (STs, GWs et SAT).
    • Monitor the status of the binaries.
  • The daemons are not anymore available and the network configuration is now external to OpenSAND, but we provide several solutions:
    • A manual and easy-to-use makefiles allowing to do a simple setup from CLI [2]
    • Different makefiles are available in order to configure/clean your network topology for different use-cases (IP/Ethernet with/without VLAN and with QoS mapping).
  • Implementation of a SARP learning mechanism given that for full-Ethernet use-cases, work-stations MAC addresses are needed in the SARP table.
  • Bug correction on the ACM loop (concerning the MODCOD selection).
  • Minor bug correction on the VBDC algorithm.

In addition to the standard way to use OpenSAND, we have added an example of an OpenSAND deployment to be executed by means of the test bench OpenBACH [3]. This example is available in the example executors [4], and you need to previously install OpenBACH and openbach-extra [5].

We will be glad to get your feedback on our mailing list [6] and bug reports on the bugtracker [7].

Welcome to OpenSAND Community

by OpenSAND team maintainers

Posted on Friday, 29 June 2012

Welcome to OpenSAND Community,

OpenSAND, formerly known as Platine, is a user-friendly and efficient tool to emulate satellite communication systems. It provides a suitable and simple means for performance evaluation and innovative access and network techniques validation. Its ability to interconnect real equipments with real applications provides excellent demonstration means.

This platform has been initially developped by Thales Alenia Space in the frame of IST european projects, R&T CNES studies and internal research. It has been also promoted by CNES (French Space Center) as a open-source reference software tool for use within its R&D activities in the domain of satellite communication systems and networks.

Please consult OpenSAND web site http://www.opensand.org/ for more information.

Don't hesitate also to ask questions and raise problems on the mailing list opensand@lists.launchpad.net, composed of all openSAND interested people.

Cordially,

OpenSAND team maintainers
