DO Packet Format

These packets are contained in the DATA QPackets for dedicated game server. It's used to send client network interface data and manage session.

Decoding / Encoding

Example: 8D 00 00 00 14 02 00 00 00 32 00 70 72 75 64 70 ...

• 8D 00 00 00 the size of the remaining bytes (excluding the checksum)

• 14 id of a called method:

    public enum METHOD
    {
        JoinRequest = 0x0,
        JoinResponse = 0x1,
        Update = 0x2,
        Delete = 0x4,
        Action = 0x5,
        CallOutcome = 0x8,
        RMCCall = 0xA,
        RMCResponse = 0xB,
        FetchRequest = 0xD,
        Bundle = 0xF,
        Migration = 0x11,
        CreateDuplicate = 0x12,
        CreateAndPromoteDuplicate = 0x13,
        GetParticipantsRequest = 0x14,
        GetParticipantsResponse = 0x15,
        NotHandledProtocol = 0xFE,
        EOS = 0xFF
    }
  

• 02 00 00 00 the number of urls sent

• 32 00 next string's length

• 70 72 75 64 70 beginning of a PRUDP URL string

• method 0x14 sends a list of prudp urls, so more size+string pairs can be appended

• 1-byte checksum at the end
