Instantiations of GXDLMSServer

Thank you Mikko,

I was really able to do it. But I still have a problem. It worked well for 1000 servers (from ports 4059 to 5058). But our system will have 40.000 (40 thousands) servers/meters. When I instantiate more than 1225 GXDLMSServer objects (with their corresponding ports), GXDLMSDirector communicates with only the first 1225 objects (I also tried with GXDLMSClient). I think I am facing tcp ports congestion. Using netstat prompt command, the assigned ports seem to be listenning, but I can't connect to those "high ports" servers.

Please, do you know a way to solve this? I'm now thinking of:

1) Creating a data concentrator or coordinator. It would receive dlms messages from the client and send them to the correct meter/server.

2) Alternatively, I could keep the servers disconnected from the network. Would it be possible to create a network listener to identify the first connection packet attempt from a client and then switch the correct server on? That would work such as a "server switcher".

You see, the problem here is that I have problems while keeping thousands of listening tcp ports.

Please, I urgently need your comment on this. I've got to make this work.

BR,

I'm using wrapper and I think it's a tcp/ip listening problem.

The thousands of servers are created, the console prompt shows the servers being created since the first port. Using netstat command I confirm: the assigned ports have the "listening" status. But actually the dlms client can only connect with the first 1225 servers. When I try to connect to the last server created, for instance, gxdlmsdirector just can't connect, as if the server wasn't listening in that port.

Would that be a restriction of my computer, in particular? My OS is Windows 7.

I'm using c++ actually.

Glad for your attention.

Ok Mikko, I appreciate it.

I don't want to be boring. But what you think about this: I could implement only few servers (1000, lets say), make them active from ports 2000 to 2999. Each server would "manage" 40 other server objects which would be disconnected (no listening port associated). Then, the client sends packets to the connected server, that would identify the desired disconnected server and load its objects.

If this were possible, I could solve my whole problem. What you think about it?

Thanks in advance,
Danilo.
