There is not much to say here – I’d like to ask which of these for protocols:
…are connection-oriented and which of them are reliable?
The protocols you list are at different communication layers, so a direct comparison doesn’t necessarily make much sense. TLS and RTP are above the transmission layer, while PPP is a link layer protocol, and these usually (not always) don’t care about connections in the sense e.g. TCP does (though link layer protocols might provide services to make sure frames are not lost and arrive in order). To make a long story short, only TCP from your list is a connection-oriented protocol. TLS and RTP work both on top of TCP and UDP.
