It’s said that “𝘵𝘩𝘦 𝘦𝘹𝘱𝘭𝘰𝘳𝘦𝘳 𝘥𝘰𝘦𝘴 𝘯𝘰𝘵 𝘧𝘰𝘤𝘶𝘴 𝘰𝘯 𝘵𝘩𝘦 𝘥𝘦𝘴𝘵𝘪𝘯𝘢𝘵𝘪𝘰𝘯, 𝘧𝘰𝘳 𝘦𝘹𝘱𝘭𝘰𝘳𝘪𝘯𝘨 𝘪𝘵𝘴𝘦𝘭𝘧 𝘪𝘴 𝘵𝘩𝘦𝘪𝘳 𝘱𝘶𝘳𝘱𝘰𝘴𝘦”. Similarly, on the open-source path, it’s not the destination that matters, but everything that happens along the way: the ideas, drafts, bugs, updates, fixes, milestones, and the contributions of those who share the same wavelength and come together to improve the world of telecommunication software.

To stay true to that spirit, 𝗕𝗜𝗦𝗗𝗡 𝗟𝗶𝗻𝘂𝘅 𝟱.𝟲.𝟬 has just been released.

BISDN Linux is an 𝗼𝗽𝗲𝗻-𝘀𝗼𝘂𝗿𝗰𝗲 𝗻𝗲𝘁𝘄𝗼𝗿𝗸 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗻𝗴 𝘀𝘆𝘀𝘁𝗲𝗺 (NOS) that runs on a class of 𝘄𝗵𝗶𝘁𝗲𝗯𝗼𝘅 𝘀𝘄𝗶𝘁𝗰𝗵𝗲𝘀 typical for small and medium data centers and telecom network appliances. BISDN Linux 5.6.0 is a 𝗳𝗲𝗮𝘁𝘂𝗿𝗲 𝗿𝗲𝗹𝗲𝗮𝘀𝗲, and 𝗮𝗱𝗱𝘀 𝗕𝗿𝗶𝗱𝗴𝗲 𝗮𝗴𝗲𝗶𝗻𝗴 𝘁𝗶𝗺𝗲 𝘀𝘂𝗽𝗽𝗼𝗿𝘁. It now follows the configured bridge ageing time, and learned entries will time out after the configured interval instead of the previous fixed 300 seconds.

BBF NetworkX 2024 Demo video available
NetworkX in Paris this year marked the end of a busy period for the BISDN team, as we could finally present the WT-474 demo(s) that were central to this year’s Innovation Demonstrations of the Broadband Forum.
A couple of weeks later, we now have the video nicely cut, thanks to Ken Pyle of BBF, and there is the full explainer on the BBF’s YouTube channel.
Building multivendor demonstrations is a big effort, and occasionally, you ask yourself if it is worth the hassle. OK, here is the answer: it is.
Recently, our CEO Hagen Woesner had the privilege to present a slide set of ‘lessons learned’ from this demo at the Fall Meeting of BBF in San Diego. The slides were discussed vividly in the working group, as we had come across some issues that were ambiguous in the Working Text.
These demos verify what we write into the TRs of BBF, and serve as anticipated plugfests. Getting closer to the notion of ‘rough consensus and running code’ that was successfully propagated by IETF, the hope is to become more relevant for the industry.
