Help me in choosing protocol

[Irfan Ahmed]

HI,

I wanted to develop an applicatioin which has to show current currency
rates to to our clients (i.e. 10 currencies and 3 or 4 changes in our
data in one second) and client may buy or sell his lots. Please let me
know if TCP/IP is right protocol to use or should I use something
else. and please let me know if I should use .NET provided TCP
protocol or should i use some third party's developed control as
someone mentioned in theses post that INDY is good comparativley to
..NET implemented TCP Protocol.

Thanking you.

Irfan,

There is no question that you should use TCP/IP. You will however probably
choose one of the protocols in the application layer, HTTP, FTP, etc.

I haven't used INDY (but I briefly looked at the docs) so I don't much about
it. Personally I believe I would look at what is provided with .Net to see
if it would handle my requirements and then look at INDY and other libraries
to see if they offered me any advantages.

If it's not necessary that every message arrives at the client, using
a connectionless protocol like UDP would make more sense.

Irfan,
Are your clients, going to use a Client that you develop?

If they are I consider using the TcpClient class and BinaryReader &
BinaryWriters to "format" the data packets.

The following article gives a C# example of how do this.

The example should be easily converted to VB.NET, post if you need help.

Hope this helps
Jay
