I got a couple of questions about gen_udp.
We are making an multiplayer strategy game this semester and we decided to go with UDP due to performance. I assume gen_udp doesn't provide reliable UDP(rudp).
What matters is to get the packages in the right order from the game clients, but we would like to avoid the TCP overheard to some extent.
The plan is to give each package an ID and collect them in the correct order on the server.
Is it possible to control the size of packages sent? (it says in the doc that the receive buffer is 8191(B?), is the send buffer the same?)
If the send and recv buffer has the same size, is it suitable split up the data every 8178B and add an ID? |

Just a follow up.
We have found out that a package size will not be larger than 4KB. So that is the limit, but feel free to post your thoughts about getting reliability.
What about storing the packages on a RAM-mnesia DB until all packages are received, and sorting afterwards? |
