Can a server have multiple clients?

Can a server have multiple clients?

Irrespective of stateful or stateless protocols, two clients can connect to same server port because for each client we can assign a different socket (as client IP will definitely differ). Same client can also have two sockets connecting to same server port – since such sockets differ by SRC-PORT .

How do servers handle multiple clients?

If a server uses a number of sub-processes in order to serve multiple requests by allocating each socket to one sub-process then it is known as a multi-threaded server. This is how the server handles multiple connections at a time.

What is client/server programming?

The client-server programming model is a distributed computing architecture that segregates information users (clients) from information providers (servers). A client is an application that needs something like a web page or IP address from a server. Clients may contact a server for this information at any time.

How do you handle multiple clients in socket programming?

A better way to handle multiple clients is by using select() linux command.

1. Select command allows to monitor multiple file descriptors, waiting until one of the file descriptors become active.
2. For example, if there is some data to be read on one of the sockets select will provide that information.

How many clients can a server handle?

But a server can (theoretically) serve 65535 simultaneous connections per client. So in practice the server is only limited by how much CPU power, memory etc. it has to serve requests, not by the number of TCP connections to the server.

How do I connect two clients to my server?

4 Answers. You can make your clients communicate through simple sockets. Once the server sends the IP of the clients, you can use the IP and the TCP port of the client (usually 443) to communicate.

How do I connect multiple clients to one server?

If a client is talking to multiple servers, it is using multiple ports on the client machine. Each time you connect() a socket, you are allocating a new port. You can specify what client port you want to use by bind()-ing to the port number. Otherwise, the operating system chooses a port for you.

What is difference between client and server?

The main difference between client and server is that a client is a machine or a program that requests for services through the web while a server is a machine or a program that provides services to the clients according to the client’s requests.

What is multithreading in network programming?

Multithreading Concepts A multithreaded program contains two or more parts that can run concurrently. Multithreaded Socket Programming describes that a Multithreaded Socket Server can communicate with more than one client at the same time in the same network.

How a socket server can communicate with multiple clients concurrently?

A server socket listens on a single port. Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.

How many connections can a webserver handle?

65535
On the TCP level the tuple (source ip, source port, destination ip, destination port) must be unique for each simultaneous connection. That means a single client cannot open more than 65535 simultaneous connections to a single server. But a server can (theoretically) serve 65535 simultaneous connections per client.

How to use multi client server in Java?

Multi Client -server Program in Java. Previous implementation of TCP Echo Server allows only one client to connect at a time To allow multiple clients to connect, use threads for each client connection in the server. We can build chat connection in java between two client using thread and multi client.

How to handle multiple clients in a server?

The simple way to handle multiple clients would be to spawn a new thread for every new client connected to the server. Semaphores: Semaphore is simply a variable that is non-negative and shared between threads. This variable is used to solve the critical section problem and to achieve process synchronization in the multiprocessing environment.

How does a client connect to a server?

The client tries to make a connection with the server using this port number and IP address. The server listens and accepts the connection. Once the connection is built, the Server can receive a message from the client as well as respond back a message to the client.
