tcp - Nagle-Like Problem -



tcp - Nagle-Like Problem -

so have real-time game, c++ sever disabled nagle using sfml library , , client using asyncsocket, disables nagle. i'm sending 30 packets every 1 second. there no problem sending client server, when sending server clients, of packets migrating. example, if i'm sending "a" , "b" in completly different packets, client reads "ab". it's happens 1 time time, makes real problem in game.

so should do? how can solve that? maybe it's in server? maybe os settings?

to clear: not using nagle still have problem. disabled in both client , server.

you have disable nagle in both peers. might want find different protocol that's record-based such sctp.

edit2

since asking protocol here's how it:

define header message. let's pick 32 bits header.

header: msg length: 16b version: 8b type: 8b

then real message comes in, having msg length bytes.

so have format, how handle things ?

server

when write message, prepend command info (the length important, really) , send whole thing. having nodelay enabled or not makes no difference.

client

i continuously receive stuff server, right ? have sort of read.

read bytes server. amount can arrive. maintain reading until you've got @ to the lowest degree 4 bytes. once have these 4 bytes, interpret them header , extract msg length keep reading until you've got @ to the lowest degree msg length bytes. you've got message , can process it

this works regardless of tcp options (such nodelay), mtu restrictions, etc.

c# - Can ProtoBuf-Net deserialize to a flat class? - protobuf-net uses nested protobuf constructs back upwards inheritance. however, can made force properties flat target class has same properties inherited "serialized" version? see test illustration below. needless result of flat namespace null both properties. possible solution: re-create info flat.b first on property property basis. note: not prefered option. using system; namespace hierarchy { using protobuf; [protocontract] public class { [protomember(1)] public string prop1 { get; set; } } [protocontract] public class b : { public b() { } [protomember(1)] public string prop2 { get; set; } public override string tostring() { homecoming "prop1=" + prop1 + ", prop2=" + prop2; } } } namespace flat { using protobuf; [protocontract] p...
