X.25 support?

[Andre Azevedo]

Hi all,

I need to receive and connect using X25 protocol in .Net Framework 2.0 and
I'm trying to find the correct address and protocol enumeration in
System.Net.Sock ets but with no success.
Is there a way to do it? Or I need some 3rd party libraries.

Any help will be apreciated.
TIA,

Hi,

X25 ??

Where r u man, it's a very old protocol not longer used .
You cannot use TCP, as a matter of fact it's a completely different
communication format.

There is no support for it in the framework, and I believe it will very hard
to find a card that support X25 that runs on a current computer (I may be
wrong on this though) the alst X.25 card I saw was in Cuba and it was a HUGE
ISA card.

Hi Mr Machin,

I'm in Brazil and most bank communication uses X25.
My plan B is using some TCP/X25 Gateway.

Thanks,

Hi,
Note that TCP over X25 is a transpotrt encapsulation, so your program should
need do nothing about that.

No idea if X25 can be used from .NET , as I said before you needed a special
card (modem) to connect to the X25 network
You need to check with the manufacturer of that card.

Plan B should be your plan A :-).
You can use the socket class to bind a TCP socket to an X25 end-point, all
you need is an X25 PC card that support TCP (Winsock) over X25 and you are
done.
Another option is to use a TCP-X25 gateway (mostly load balanced hosting
servers), this is what's been used in most financial institutions here in
europe.

Hi Mr Denoyette,

The scenario it's the same here. Thanks!
Can you help about some questions?

In both cases you describe all the communications is made with stream/tcp
connection, right?

So, if I use a X25 pc card that support TCP over X25 the card software will
create some kind of X25 host server and all my tcp communication is made
through it. If I have more than 1 virtual link with this card, the host will
split in different port numbers? or different IP numbers?

In the case of using a Gateway, afaik, the server will do the conversation
of 2 kind of networks and probably the software take care of X25 Cards
(which in fact it's the same scenario of item 1). Is this right?

Thanks in advance,

So, if I use a X25 pc card that support TCP over X25 the card software
will create some kind of X25 host server and all my tcp communication is
made through it. If I have more than 1 virtual link with this card, the
host will split in different port numbers? or different IP numbers?

It depends on the type of card, basically you get a single physical X25 port
and IP address and a TCP/UDP port per virtual channel (X25) for the cheapest
solutions. More expensive cards can support multiple X25 ports and IP
addresses with again multiple ports per VC. All configuration settings like
IP/X25 address and VC/port mapping is done by software, all cards I know do
support RAS dialing and PPP.
In the case of using a Gateway, afaik, the server will do the conversation
of 2 kind of networks and probably the software take care of X25 Cards
(which in fact it's the same scenario of item 1). Is this right?

Same as above because these hosting Gateway servers are equiped with the
same PC cards supporting load balancing options and failover facilities
(multi-hosted). This is a quite expensive solution, but for a financial org.
this should not be an issue.

Willy.
