49 Protocol oriented to internal network messages interchange, supposing no errors in transmision and short-sized
50 messages which allows length representation in only two bytes. No synchronization mechanisms are provided, then
51 a single error could cause problems in our process.
53 @warning Encode mode does not provide enough information to allow re-synchronization in case of error
