That's not because of ossification, it's because of middleware boxes like NATs and firewalls that will refuse to pass anything that isn't TCP, UDP, or ICMP.
- bonzini 5y agoWhich is an example of ossification, in this case at the IP level.
- azernik 5y agoFrom context, I assumed detaro was referring to an ossification of SCTP.
- detaro 5y agoAh, yes, that wasn't quite clear, sorry. No, I was referring to the ossification of middleboxes/OSes/knowledge/... that made it unviable to support a new IP protocol alongside the existing ones for the general internet case.
- touisteur 5y agoSctp over UDP is a thing and still hasn't gained much general public use over the net... Sadly!
- Orphis 5y agoSCTP over DTLS over ICE over UDP is used quite a lot though! That's how DataChannels in WebRTC were specified a while ago, and it's the only mechanism to do browser to browser communication.
- touisteur 5y agoOh yes, when I discovered SCTP I felt so sad for all time I and hundred others had implemented part of its featureset over the last 30 years... I mean, it was packed with great features like separate streams, packet-based, multi-homing and multipath. It felt so right playing with it. Alas, even in my company I failed to convince it was a great replacement for layers upon layers of working udp code. I think it came too late...
