Generally speaking, security devices need to support a lot more than just raw IP to do their jobs these days. At this point the installed base of firewalls alone would make implementing a new protocol like this across the internet effectively impossible.
Add in devices that do NAT, ALGs, load balancers, and other intelligent network devices and you can see why everyone that needs something like this on a real network uses UDP with stuff built on top.
- nrjdhsbsid 10y agoHad the OSI network model won out eons ago we would have enough separation between layers to use custom protocols. For better or worse, that battle was long decided by TCP/IP and the two have been tightly intertwined ever since. It's too bad but at the same time running custom protocols on UDP really isn't too bad as far as CPU/Space overhead. It's pretty much become a universal encapsulation protocol for everything else
