Control Protocol
Because of historical reasons, the latest control protocol adopts variable-length and is fully
compatible with old fixed-length control protocols. In protocols, the fourth byte is used to distinguish
versions. 0- indicates V1 version (previous versions) and 1- indicates V2 version (current protocol
version).
