Hello,

1) Run server on remove machine (trying on amazon and hetzner servers)
What is a "remove machine"?

Code: Select all

2) Run 10-15 client instances on other machine (behind router) and wait their connecting, logginig and "find game". 
When client sends "find game" they are added to list of waitining players. After 10 players joined to "the lobby" - on the server side i 
create room with "battle" extension and start loadind "battle scene" on the clients. After clients loaded the scene, they send 
join battle request. After they have joined the battle, all clients send "Attack request" and some times i get this error.
So what you're basically saying is that you join 10 players in a Room, and the problem happens after a while?
What is the average packet rate of a client?

What is exactly an "Attack request"? What does it do?

remote machine* (dedicated server on hetzner or amazon)

the problem happens exactly after sending "attack request".
What is the average packet rate of a client?
one request after joinig to the room per client. Server sends "move data" to clients each 40 millisec
What is exactly an "Attack request"? What does it do?
Attack request it's a dummy echo request in test project. In our project this request is used to attack by player.

Ah sure, sorry. :)
one request after joinig to the room per client. Server sends "move data" to clients each 40 millisec
Attack request it's a dummy echo request in test project. In our project this request is used to attack by player.
So let me understand the communication better.
The server sends "move data" to clients every 40 millisec. But how often each client is updating their position in your test?

thanks

In test they are not updating positions. They only recive data and do nothing with it.

In original project clients interpolate their position each time they receive move data from server.

Thanks.
There still something not clear. The error message you have reported: "Discard UDP packet from..." appears only for incoming packets. If the server is the only one sending data and the client is not firing any updates I can't see how this can cause such an error.

Am I missing something else?

Meanwhile I will take a look at the files you have sent.
Thanks

Am I missing something else?
1) Client connect and login to ZoneExtension
2) On client login success, client send TCP ZoneExtension Request "FindGame".

2.1) ZoneExtension handle "FindGameHandler" Add player to list and send to all players in list response with data about players in list. (Lobby)
2.2) When 10 players added to list - battle begins:
2.3) ZoneExtension Creates Game Room and assign to the room battle RoomExtension
2.4) On RoomExtension Initialize - create schedule with fixed rate 40 milliseconds wich sends to all users in the room UDP Response "Move" with all players positions data
2.5) ZoneExtension send TCP Response "CreateGame" with battle data to all players in list and clear that list

3) Client receives TCP response from server "CreateGame" with battle data and start loading "BattleScene"
4) When BattleScene loaded - Client send TCP ZoneExtension Request "JoinGame"

4.1) ZoneExtension handle JoinGameHandler and join current user to the game room
4.2) Game RoomExtension Rise "JoinRoomHandler" and send to all users in the room TCP Response "EnterToBattle" with data about connected player

5) Client joined to the room and start receiving UDP Response "Move" with all players positions data.
6) Client receive TCP Response "EnterToBattle"
7) Client Send UDP Request "Attack" and some players got error about wrong port.

We'll setup a test environment, see if we can reproduce this and report back

We have run a test reproducing a similar scenario with 10 players, 40 milliseconds messages to all players using the same data you use over UDP. The client doesn't do very much besides sending an occasional request every few seconds.

Run the test with a remote server for over an hour with no errors whatsoever.

Our client is Java rather than C# because it's easier for us to build tests with a Java-based tool. Although the type of client should make no difference whatsoever.

Do you run your test from a desktop machine? Which OS?
Any firewalls running?

Attached are a screenshot of the server's Dashboard screenshot of the test and the server's logs.

Re: Server dropping UDP packets

Post by Zed »

Do you run your test from a desktop machine? Which OS?
Yes, from the desktop.
OS Windows 7 x64
Any firewalls running?
i have turned off firewall but this not solve the problem.

I think, maybe problem apear when server try to send TCP zone and UDP room response at same time?
Can you try run my test project on test environment?

Are you referring to the standard windows firewall or something else?

No, it's not possible. TCP traffic is not a trigger for a UDP port change. This is typically done by a node in between or a firewall.

We'll try that.

Re: Server dropping UDP packets

Post by Lapo »

We've run your test for over an hour. Clients behind a router and through a VPN from our office in Italy. Server is hosted on Rackspace (USA, Chicago I believe). We haven't found any issues. (see attached screenshot and logs)

If you want you can test on our servers from your place and see if it makes any difference. I don't expect it will though, as this is typically a client side issue.

You can reach us at our support@... email. Just add a reference to this discussion for clarity.

Thanks.

p.s. = here are the logs of the session:

Re: Server dropping UDP packets

Post by Lapo »

One extra note: running 10 copies of the Unity client is pretty heavy on system resources causing my Intel i7, quad-core MBPro to use almost all CPU (94% overall, across all cores).

I would recommend to check the status of your testing machine CPU to avoid a 100% usage. If the test maxes out the CPU clients will start to lag and fall behind which ultimately can cause issues and invalidate the test. If that's the case it would be best to lower the number of clients so that the machine has some resources left.

cheers

One extra note
I get this error not only on PC. In original project the issue cause on one instance per client (IOS/Android) (MOBA for 4 players).
i have created test project with 10 client to show you the way i get the error.
This error does not depend on time. It appears on start of the clients after they connect and receive battle data.
