The highest TCP port number is 65, You can only have one application listening on the same port at one time. Now if you had 2 network cards, you could have one application listen on the first IP and the second one on the second IP using the same port number. For UDP Multicasts , multiple applications can subscribe to the same port. When using multiple cameras, set the server port to 85 for the first camera, 86 for the second and 87 for the third.
If you wish to add multiple cameras, simply continue in this fashion and add the details of the camera to your port forwarding configuration. If an app opens too many simultaneous TCP connections, the size of each connection will be smaller.
This means that throughput will be limited, performance will decrease, and energy will be wasted. A port is a virtualisation identifier defining a service endpoint as distinct from a service instance endpoint aka session identifier.
Both Socket and Port are the terms used in Transport Layer. Save my name, email, and website in this browser for the next time I comment. Skip to content How many requests per second can a Web server handle? What is a reasonable API rate limit? What are the limits of API usage?
What is a good requests per second? Average connections per second. How many users can access a website at a time? How many requests can a node server handle?

How many WebSocket connections can a server handle? Can two clients connected to same port? How many connections can a single port handle? How long does a rate limit last? Whether the CGN can simultaneously open connections to one server and connections to another server is an implementation detail, which can vary between different CGN implementations. But you can also just deploy dual stack. Then connections to servers with IPv6 support won't go through the CGN, so they won't be consuming precious port numbers.
Dennis Kaarsemaker, can you also please have a look at this question? LImit is connections per ip address. Show 1 more comment. Emanuel Adrian Lucaci 3 2 2 bronze badges. There are multiple ways to share load across multiple servers; DNS round robin is one; there are others Deploy "carrier-grade NAT" which a friend derisively and correctly in my view refers to as "crummier-grade NAT". If you read more than the title, you'll see that this question is about port exhaustion and the OP was mistaken about how it works.
How exactly does this answer add anything new of value to that? The OP asks explicitly and not just in the headline "how do servers experiencing extremely high amounts Leaving aside the confusion over how sockets work, that's a valid question. Excellent job of cutting off the question mid-sentence. The rest of that sentence says: more than the max port number.
Perhaps you missed the part where I stipulated the OP doesn't understand socket mechanics. I'm of the opinion that how to exceed 64k ports is a valid topic for discussion; I'm sorry if you disagree, but that WAS the question and that WAS what I provided a couple of answers for. 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.
