It tries to describe in detail what are the minimal semantic preconditions for protocol implementations to be composable (both vertically and horizontally) while at the same time being efficient (so that a stack with 20 microprotocols won't grind to a halt). The most interesting parts are handshakes, how they are conflated among multiple protocols as well as semantics of error handling.
But the real proposition here is to have an ecosystem of microprotocols (e.g. a CRLF protocol that splits bytestream into messages using CR+LF as a delimiter) which, by the virtue of having common, well understood semantics, could by composed into ad-hoc networking stacks according to users' needs.
