Completed! Not Tested yet! But I think it works.

By: William
Difficulty: 3/5
Source: http://www.key2heaven.net/Socket2.rar

Thanks to Bhenur for the idea and explanation behind it.

Introduction
Backup your source!
Currently, the movement is handled through the same socket as everything else that sends from the client to the server. This tutorial will add two new sockets. One to the client and one to the server that handles the movement. So the sending delays decreases.

Client Side
Begin with adding a new socket to frmMirage. Name it "Socket2" without the quote tags.
Find:

Code:

frmMirage.Socket.RemoteHost = GAME_IP
    frmMirage.Socket.RemotePort = GAME_PORT

Below add:

Code:

frmMirage.Socket2.RemoteHost = GAME_IP
    frmMirage.Socket2.RemotePort = GAME_PORT2

Find:

Code:

Sub TcpDestroy()
    frmMirage.Socket.Close

Replace it with:

Code:

Sub TcpDestroy()
    frmMirage.Socket.Close
    frmMirage.Socket2.Close

Under:

Code:

Sub IncomingData(ByVal DataLength As Long)

Add this sub:

Code:

Sub IncomingData2(ByVal DataLength As Long)
Dim Buffer As String
Dim Packet As String
Dim top As String * 3
Dim Start As Integer

    frmMirage.Socket2.GetData Buffer, vbString, DataLength
    PlayerBuffer = PlayerBuffer & Buffer
        
    Start = InStr(PlayerBuffer, END_CHAR)
    Do While Start > 0
        Packet = Mid(PlayerBuffer, 1, Start - 1)
        PlayerBuffer = Mid(PlayerBuffer, Start + 1, Len(PlayerBuffer))
        Start = InStr(PlayerBuffer, END_CHAR)
        If Len(Packet) > 0 Then
            Call HandleData(Packet)
        End If
    Loop
End Sub

Under:

Code:

Public Function ConnectToServer() As Boolean

Add:

Code:

Public Function ConnectToServer2() As Boolean
'****************************************************************
'* WHEN        WHO        WHAT
'* ----        ---        ----
'* 07/12/2005  Shannara   Optimized function.
'****************************************************************

Dim Wait As Long

    ' Check to see if we are already connected, if so just exit
    If IsConnected2 Then
        ConnectToServer2 = True
        Exit Function
    End If
    
    Wait = GetTickCount
    With frmMirage.Socket2
        .Close
        .Connect
    End With
    
    ' Wait until connected or 3 seconds have passed and report the server being down
    Do While (Not IsConnected2) And (GetTickCount <= Wait + 3000)
        DoEvents
    Loop
    
    If IsConnected2 Then
        ConnectToServer2 = True
    Else
        ConnectToServer2 = False
    End If
End Function

Under:

Code:

Function IsConnected() As Boolean

Add:

Code:

Function IsConnected2() As Boolean
    If frmMirage.Socket2.State = sckConnected Then
        IsConnected2 = True
    Else
        IsConnected2 = False
    End If
End Function

Under:

Code:

Private Sub Socket_DataArrival(ByVal bytesTotal As Long)

Add:

Code:

Private Sub Socket2_DataArrival(ByVal bytesTotal As Long)
    If IsConnected2 Then
        Call IncomingData2(bytesTotal)
    End If
End Sub

Under:

Code:

Public Const GAME_PORT = 7000

Add:

Code:

Public Const GAME_PORT2 = 7001

Make sure to open the new port in your router.
Replace:

Code:

Sub SendPlayerMove()
Dim Packet As String

    Packet = "playermove" & SEP_CHAR & GetPlayerDir(MyIndex) & SEP_CHAR & Player(MyIndex).Moving & SEP_CHAR & END_CHAR
    Call SendData(Packet)
End Sub

Sub SendPlayerDir()
Dim Packet As String

    Packet = "playerdir" & SEP_CHAR & GetPlayerDir(MyIndex) & SEP_CHAR & END_CHAR
    Call SendData(Packet)
End Sub

With this:

Code:

Sub SendPlayerMove()
Dim Packet As String

    Packet = "playermove" & SEP_CHAR & GetPlayerDir(MyIndex) & SEP_CHAR & Player(MyIndex).Moving & SEP_CHAR & END_CHAR
    Call SendData2(Packet)
End Sub

Sub SendPlayerDir()
Dim Packet As String

    Packet = "playerdir" & SEP_CHAR & GetPlayerDir(MyIndex) & SEP_CHAR & END_CHAR
    Call SendData2(Packet)
End Sub

Under:

Code:

Sub SendData(ByVal Data As String)

Add:

Code:

Sub SendData2(ByVal Data As String)
    If IsConnected2 Then
        frmMirage.Socket2.SendData Data
        DoEvents
    End If
End Sub

Replace your whole:

Code:

Public Sub MenuState(ByVal State As Long)

With this:

Code:

Public Sub MenuState(ByVal State As Long)

            End If
    End Select

    If Not IsConnected Or Not IsConnected2 Then

        frmSendGetData.Visible = False
        Call MsgBox("Sorry, the server seems to be down.  Please try to reconnect in a few minutes or visit " & WEBSITE, vbOKOnly, GAME_NAME)
    End If
End Sub

Whats added above are the "If IsConnected2 = True" on the menu_states. And also the last extra "Or Not IsConnected2".

The tutorial is completed. This source has it added and works great: http://www.key2heaven.net/Socket2.rar

Feel free to test the tutorial and see if I remembered to put everything into it. Thanks

Hopefully someone who has some knowledge in this could say some words what this does so people will trust it :P

What exactly does it do? Just a separate socket for movement?

Yeah, instead of letting everything getting buffered and such in one socket. The new movement socket handles only movement and therefore decreases the delay and preassure on the main socket

I dont have so much knowledge in what benefits it has. But sounded like a good idea when bhenur told me about it. And that wow uses like 4-5 for it

Hopyfully Bhenur can explain some about it, since he recently read up on this kind of things.

From the reference:
Congestion control

The final part to TCP is congestion control. TCP uses a number of mechanisms to achieve high performance and avoid 'congestion collapse', where network performance can fall by several orders of magnitude. These mechanisms control the rate of data entering the network, keeping the data flow below a rate that would trigger collapse.

Acknowledgments for data sent, or lack of acknowledgments, are used by senders to implicitly interpret network conditions between the TCP sender and receiver. Coupled with timers, TCP senders and receivers can alter the behavior of the flow of data. This is more generally referred to as flow control, congestion control and/or network congestion avoidance.

Modern implementations of TCP contain four intertwined algorithms: Slow-start, congestion avoidance, fast retransmit, and fast recovery (RFC2581).

Enhancing TCP to reliably handle loss, minimize errors, manage congestion and go fast in very high-speed environments are ongoing areas of research and standards development.

I don't think i need to shed more light on this really, William did a decent job.

For a practical example check out the plugin for Firefox called DownThemAll at http://www.downthemall.net/. This plugin accelerates your downloads by breaking files into 5 parts - each on different TCP connections.

good job William well i like it allot, so Iâ€™m giving you a 10/10 and the right to use my particle system into a tutorial teaching hem how to use bitblt particle system. thatâ€™s if you want to. I would do it but as I told you I rather not because I donâ€™t truly think they deserve stuff like that. But thatâ€™s up to you William I leave it in your hands.

If you wanna talk about deserving something, you don't deserve to be here. We've all helped you enormous amounts of time. And you've asked me to join in several retarded projects. Like an OS made in VB..? Dude..

Anyways..

William, how much will this change? Is it really worth putting it in? I've yet to see much of a problem in my game, but that's also because it's not that popular yet so we don't have a lot of players on..

Genusis, you are our guest here and the way you a behaving is unacceptable.

Either step in line or get back to Elysium, where you belong.

frozen you really should read through a tutorial first.

This won't effect your FPS or speed at all, it is simply trying to relieve some of the main sockets stress by receiving the most common packets through a different socket.

I think this mod is more organizational than functional.

I think the winsock send function in VB is blocking, which means it haults the program until it is sent. This fact eliminates any advantage to sending packets faster.

Downthemall uses multiple sockets to download from a connection that may have upload limits. If there's an upload limit per socket, then using one will only get you so fast. Using two will get you double that, etc. In a mirage environment where there is no limit to how fast a socket can be, there is no real advantage to using multiple sockets as far as I know...

I just recently did a lot of research on winsock

So Dave, your saying that the tutorial doesn't do much good? I was thinking that dividing it into 2 sockets would decrease a lot of preassure on the socket. And also smoothen the movement a tiny bit too since it can send a packet from both sockets at the exact same time.

Guys lets just be simple,

send 100 cars down a 1 lane road they are going to have to wait on each other a lil,

send 50 cars down a road each its going to make things easier and reduce waiting times,

its not that difficult...

Other online modern games use like 23874297482734 gazillion sockets, kinda seems stupid just to utilize one,

cant be a step backwards, it just cant; logic negates that

I dunno much about winsock, or if what I'm about to say is even true, it's just a theory to combat what you said.

If the program only allows for one to be active at a time, then there is no point in having both. Know what I mean?

You can have more than one socket active at a time...

Send 100 cars down a one lane road when you can only send one car at a time. You get no speed bonus from adding more lanes.

You can only send one packet at a time (you can not call send() twice at the same time)
You can only receive one packet at a time (you can not call receive() twice at the same time)

Explain to me where the speed increase is?

why cant you handle multiple packets using different sockets?

Obviously the call senddata can't ran twice at the exact same time. But if you are running and typing at the same time, and you hit enter while running. The movement socket wont need to deal with the message being sent.

The movement socket is independent on all the other data being sent.

It can still only send one thing at a time, so I don't see how it would make much of a difference..

It doesn't make much of a difference, but it do affect it a little. There is no downside by adding this. And unless you guys come up with a strong case why this wouldn't decrease the sending delay, I still think it's a decent thing that could be added.

If it can't call that sub more than once at the exact time, it's the same as one socket.

If you checked my tutorial, it doesn't use the same senddata sub, since senddata is linked to socket1, and my senddata2 sub is linked to socket2. This way both those subs can run at the same time.

Its just senddata that cant be run at the same time twice. But by having two subs for the sending, it can.
