Minetest-c55 protocol (incomplete, early draft):
Updated 2011-06-18
A custom protocol over UDP.
Initialization:
- A dummy reliable packet with peer_id=PEER_ID_INEXISTENT=0 is sent to the server:
- Actually this can be sent without the reliable packet header, too, i guess,
but the sequence number in the header allows the sender to re-send the
packet without accidentally getting a double initialization.
- Packet content:
# Basic header
u32 protocol_id = PROTOCOL_ID = 0x4f457403
u16 sender_peer_id = PEER_ID_INEXISTENT = 0
u8 channel = 0
# Reliable packet header
u8 type = TYPE_RELIABLE = 3
u16 seqnum = SEQNUM_INITIAL = 6550
# Original packet header
u8 type = TYPE_ORIGINAL = 1
# And no actual payload.
- Server responds with something like this:
- Packet content:
# Basic header
u32 protocol_id = PROTOCOL_ID = 0x4f457403
u16 sender_peer_id = PEER_ID_INEXISTENT = 0
u8 channel = 0
# Control packet header
u8 type = TYPE_CONTROL = 0
u8 controltype = CONTROLTYPE_SET_PEER_ID = 1
u16 peer_id_new = assigned peer id to client (other than 0 or 1)
