Networking
Command
Stream: Command #0 | Response command #0 | Broadcast command #1
Client -> Command #0
Server <- Command #0
Server -> Response command #0
Client <- Response command #0
Server -> Broadcast command #1
Client <- Broadcast command #1
Command is likely unordered. To match response and request, use header id.
Secure data
Stream: Handshake | Secure data #0 | Secure data #1
Client -> Handshake
Client -> Secure data #0
Server <- Secure data #0
Server -> Secure data #1
Client <- Secure data #1
