Separating messages in Protocol Buffers

I am building an UDP messaging system with Protocol Buffers. I have several messages (e.g. ChannelUpdate, MessageCreate, ACK). If I send a message to the remote, how can I also send what type of message I am sending?

Your best bet is to always send the same message type: a root message that has one of the others. For example:

message SomeRoot {
  oneof content {
    ChannelUpdate channelUpdate = 1;
    MessageCreate msgCreate = 2;
    // etc
  }
}

Now you're using an inbuilt protocol feature to enforce the logic.
