i am to design a server that needs to serve millions of clients that are simultaneously connected with the server via TCP.

the data traffic between the server and the clients may be sparse. so bandwidth issue can be ignored.

one important requirement is that whenever the server needs to send data to any client it can use the existing TCP connection instead of opening a new connection toward the client (because client can be behind a firewall).

does anybody know how to do it and what hardware/software is needed (at the least cost)?

thanks in advance for any suggestion.

I'm suspecting an attack, but not sure. Intermittently, the web server will stop responding. When this happens… >>> More
