So I tried to document a potential pitfall with layer 3 #multicast routing, with #PIM in particular, here: https://wiki.dn42.dev/howto/pim-multicast-vs-unicast-issue
The issue of multicast potentially being black holed if the unicast topology is larger than the potential multicast one. I'm wondering how other people tackle or avoid this or if I'm missing an easy solution.
(I'm wondering if maybe @troglobit or @dentangle might have some ideas?)

@OlivierAuber hum - AGI is a mirage we should not seek to catch.
human intelligence in a society helped with communication tech is, But indeed it's captured now for decades.
#Multicast is not profiting authoritarianism in any way, so I would really not bet huawei is going to invest in it either. It needs multipolar worlds entities collaborating together, not competing for power. This could come if ppl awake from the current slopness (as a next history wave)
imho it was not a effective stage
@olm_e @OlivierAuber Agreed. While we're waiting for the AI/LLM bubble to pop lets keep building the systems we need to help society recover from the mess that will be left behind.
#Multicast can help us build truly decentralized systems that do not rely on the same centralized, profit-driven corporations that are stoking this AI/LLM bubble.

Ma discussion "au coin du feu" avec Ben Goertzel au #BGIsummit Istanbul
I reclaim the original DISTRIBUTED architecture of the internet
"CISCO, why not opening #Multicast for #SingularityNet #agi
Et j'ai ajouté en off : "If CISCO don't, Huawei will"

I wonder if @librecast has some plans or even a lobby in the EU to advance the adoption of #Multicast in the near future. If there's any time the @EU_Commission would be interested in a major technological shift (due to digital sovereignity efforts) it's probably right now.
To my understanding the underlying capabilities (below layer 5) are already there, it really just needs the political will to enforce it being enabled in routers etc.
Or are there still big fundamental hurdles? 🤔 @dentangle

We've got some good news thanks to @nlnet and @NGIZero 🎉
Librecast has been funded to do more awesome things with #multicast

Personal social networking is where 💪 people are in control and free to live their daily life.
Dodge the dodgy #AI infested corporate #streaming services and zoom out, as on the #fediverse we own the stream. Here are platforms that offer #streaming of #video or #audio in real time or near real time, with live chat and other #social capabilities.
On the fediverse our 💜 #lifestreams meet people and humanity and we engage our favorite fedi crowds. Fedi is where outreach matters.
#Librecast LIVE. @librecast is a research project aiming to bring #Multicast to the masses.
We've got a new tool! lcagent version 0.1.0, the #Librecast #multicast agent.
In server mode, lcagent can be configured to listen on Librecast Channels (multicast groups) and execute programs in response to packet data received on those Channels.
Packets must be accompanied by an authorized token and signed by the matching key or they will be silently dropped.
Data is encoded with #RaptorQ using Librecast’s liblcrq library to provide forward error correction in the event of packet loss.
lcagent can be used to send and receive data over #multicast and to pipe data between programs on one computer and as many receivers as the multicast network can support simultaneously. We're currently using it now to run our own CI builds by multicasting the patch to multiple build servers simultaneously.
This could also be useful for monitoring and configuration management.

@dlakelan @mray You're technically correct (the best kind!)
Yes, SSM is PULL rather than PUSH, so it has one of the properties of multicast, but it is lacking the other characteristics that make multicast special.
SSM relies on knowing in advance the *unicast* IP address of the source.
SSM is unidirectional.
SSM lets one sender shout at everyone else.
SSM is not group communication.
SSM has its uses, and it's easier than true #multicast but it doesn't meet #Librecast 's requirements.
It's a new release of Librecast! 🎉
This release adds restricted channel support with token based authentication. This allows keyrings to be created and filters to be applied to channels such that any data arriving which is not signed and accompanied by a token issued by an authorised key will be dropped.
Use #BSD for good networking, nuff said... Use #OPNsense for a firewall/router, nuff said...
Me trying to use #multicast snooping with this in our hackspace: After several hours of debugging, realizing it's not bc. of the #OpenWrt powered, #rtl83xx based switch I've added, nor the new patches I've made and added to it. But because of this two years old, ignored #OPNsense (or #FreeBSD?) bug with #MLD: https://github.com/opnsense/core/issues/6247
😒 😤
Every time I `git commit` now my computer is sending patches over #IPv6 #multicast to our CI system (a bunch of test machines and VMs running on qemu) and this is how development should be.
`git pull` ?! Pah! You unicast kids with your centralized servers! 😉
