Hi, Just checking in to see if the information provided was helpful. If yes, you may accept useful reply as answer, if not, welcome to feedback. Best Regards, Sunny. To send data accurately and quickly, you need to know the basics of TCP. Bytes stuffed in one side of a TCP connection come out the other side correctly, and in the right order see Figure TCP takes the stream of data, chops up the data stream into chunks called segments, and transports the segments across the Internet inside envelopes called IP packets see Figure Each of these IP packets contains:.
The IP header contains the source and destination IP addresses, the size, and other flags. Figure A computer might have several TCP connections open at any one time. TCP keeps all these connections straight through port numbers. A TCP connection is distinguished by four values:. Together, these four values uniquely define a connection. Two different TCP connections are not allowed to have the same values for all four address components but different connections can have the same values for some of the components.
Jeremy Friesner Jeremy Friesner This doesn't answer the question at all. Regardless of the accuracy of what you have said, there would still be a number of concurrent TCP connections at a given time, what's the maximum?
This is the essence of the question. If you have something worthwhile to contribute, Todd, by all means go ahead and do so. I already had an Answer on the 28th of March, you must have missed it. But even if it is shortlived there is still a maximum number of concurrent connections. Attempting to explain away the question is not an anwer IMO. This answer would be better placed as a comment on the question, it's certainly useful, but the question pertains to "socket connections", not "people".
A question on ratio users : active connections should be a separate question if desired. Keep Alive on HTTP TCP connections has been around and requested by browsers since the last millennium - it is up to the server if it allows the connection to stay alive and what the idle time-out period will be.
Allowing Keep Alive reduces the latency of a group of requests eg a html page and its associated assets , but increases resource usage on the server.

Also this question pertains to "socket connections" not "people", which is an important distinction in the context of this question.
If we are talking about one single server machine and one single router, I think this answer is right. But Todd is taking about a farm of server machines, which the user can connect to any of them randomly through a load balancer.
My answer is about a single machine. The "Webfarm? You simply haven't read my answer thoroughly yet. Oladipo Olasemo Oladipo Olasemo 1, 22 22 silver badges 29 29 bronze badges. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

You asked how this was responsive; that's how. That's half the question. The bigger-picture question -- as supported by the OP's final sentence -- is how to break the 64k barrier.
