Re: [twsocket] best way for packet routing
Hi, yes I know that packets are biggest than 4 bytes on wire, I'm telling about payload only. [40(eth)+20(ip)+20(tcp)+4(payload)]*1000(pktps)*8(bits)*500(clients)=336Mbps1Gbps My intention is to stress the software and understand what happens in critical situations. If I use bigger packets I can easily saturate the gigabit switch, but what I want is to send a lot of packets to a lot of clients using less bandwidth as possible. Do you think that routing cicle is ok? There is a better way to do that? Can you give any advice about that? Thank you Il 27/02/2012 20:50, François Piette ha scritto: For this I configured each client to send about 1000 packets per second of 4 bytes (about 32Kbps). Your bps computation is wrong. You send 4 data bytes, the actual packets on the network are much larger (something like 10 times) ! Have a lokk there: http://sd.wareonearth.com/~phil/net/overhead/ You should avoid transmitting such small packet. It is better to aggregate small packets into larger ones. fSS.Client [i]. Send (fRxData, lSize) Add a try/except block around that line. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be -- Ing.

[twsocket] SSL ErrCode 3
I have problem with SSL components from ICS Overbyte package. I have
similar problem like this person here:
http://www.archivum.info/twsocket@elists.org/2007-02/00013/(twsocket)-SSL-ErrCode-3.html
What happens is that everything works on my machine perfectly, but when
I copy my application to another machine, I get ErrCode 3 in
OnRequestDone() event of http ssl component.
I am unable to find ICS SSL list Arno mentioned, from April 2006, to
check for answer about fix.
I don't call .Abort() anywhere in code, which would cause this error.
Here is how I do the operations:
[code]
procedure TCertificateWindow.btDownloadCert(Sender: TObject);
begin
sslClient.URL := ebAddCert.Text;
If Pos('https://', LowerCase(sslClient.URL)) 1 Then
sslClient.URL := 'https://' + sslClient.URL;
sslClient.GetAsync;
end;
procedure TCertificateWindow.sslClientSslHandshakeDone(Sender: TObject;
ErrCode: Word; PeerCert: TX509Base; var Disconnect: Boolean);
begin
Disconnect := FALSE;
end;
procedure TCertificateWindow.sslClientSslVerifyPeer(Sender: TObject; var
Ok: Integer; Cert: TX509Base);
begin
Certificates.AddCertificate(Cert.GetRawText);
Ok := 1;
end;
[/code]
What happens after .GetAsync() is that none of these events get called.
I debugged further, and figured out that OnSocketError(Sender: TObject);
event gets called, but when I check values of
sslClient.CtrlSocket.LastError and sslClient.CtrlSocket.LastSslError
inside that event, they are zero. I have also tried to call non-async
.Get(), but I get same error.
However, when I check CtrlSocket.LastError value in OnRequestDone()
event, it is 10035 (WSAEWOULDBLOCK).
I use latest ICS package and tested on machine without firewall and AV.
Does anyone know what the problem could be ?
Thanks in advance, Marko.

Re: [twsocket] OFF: string issues while porting WebSockets server to BDS 2010
Apologies for the disturbance, I've found the solution - AnsiChar. Now all is working fine. - Original Message - From: Stan To: ICS support mailing Sent: Tuesday, February 28, 2012 10:43 PM Subject: OFF: string issues while porting WebSockets server to BDS 2010 Hi, I have a working WebSockets server for ICS, which I plan to share. It is implemented initially in Delphi 7. Now I try to port it to BDS2010 and have some issues with strings. First, I replaced all 'string's with 'AnsiString's, and this seems working as expected. But Chr function produces a problem. If I have an AnsiString str, and try to call str := Chr(b), where b is Byte with value 129, I get the symbol '?', which should normally be another non-standard so to speak character. So the question is, how to use Chr in BDS without any smart interferences, or how can I pack bytes in a AnsiString without using Chr?

Re: [twsocket] best way for packet routing
Do you think that routing cicle is ok? There is a better way to do that? Can you give any advice about that? How do you solve the issue which can happen if a client is not receiving data fast enough ? The sending socket will buffer data (It is asynchronous on send as well) and all memory could be consumed if you don't kill client which do not receive data, or at least delete some data (the oldest or the newest). Also, with your system, data is duplicated as much as you have clients. This is a waste of memory and will not scale up nicely. -- francois.pie...@overbyte.be The author of the freeware multi-tier middleware MidWare The author of the freeware Internet Component Suite (ICS) http://www.overbyte.be -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
