Oddly enough some OSI protocols live on at the foundation of IP networks in the form of CLNS & IS-IS.
IS-IS is a internal routing protocol sometimes used instead of OSPF.
- jws 12y agoASN.1 managed to infest some internet protocols like SNMP and SSL certificates. It's one of those solutions to a problem that shows its committee heritage and ends up being ludicrously complicated to implement because of all the edge cases. Lots of software has been compromised through flawed ASN.1 and X.509 decoders. I'm old enough to remember back in the day when our customer (the biggest possible customer) allowed us to implement early versions using SMTP, but we had to design and plan to switch to X.400 since that was going to be the real standard. It was a strange era. We had things that worked, but everyone knew that the whole industry was going to switch to something completely different that solved all the same problems for a reason no one in the trenches really understood. Except the dates for switching kept moving and the software for the new way never really quite arrived in working order or with enough features to move.
