This project implements a multithreaded web server capable of handling multiple concurrent client requests efficiently. It leverages thread pools to manage resources effectively and demonstrates key concepts such as client-server communication, TCP sockets, and multithreading.
- Multithreaded Server: Handles multiple client requests simultaneously.
- Thread Pool Implementation: Optimizes server performance by reusing threads.
- TCP Communication: Ensures reliable data transfer between the client and server.
- Scalable Design: Supports concurrent connections with controlled resource usage.
- Client Simulation: Generates multiple client requests to test server performance.
- The server listens on a specified port and handles incoming requests from multiple clients.
- The client establishes a connection to the server, sends a request, and receives a response.
- Uses TCP for reliable, ordered, and error-checked communication.
- Demonstrates the TCP three-way handshake for establishing a connection.
- Implements basic server responses similar to HTTP protocols.
- Simulates the behavior of HTTP 1.0 (non-persistent) and HTTP 1.1 (persistent) connections.
- Utilizes Java's
Socket
andServerSocket
classes for network communication. - Demonstrates socket operations: opening, listening, accepting, reading, and writing.
- Processes each client request in a separate thread.
- Uses
ExecutorService
to manage threads efficiently via a thread pool.
The server code:
- Listens for incoming connections on a specified port (default:
8010
). - Uses a thread pool to process each client request concurrently.
- Responds to each client with a greeting message.
The client code:
- Simulates multiple clients using a thread pool.
- Each thread represents a client connecting to the server, sending a request, and receiving a response.
- Java Development Kit (JDK) installed (version 8 or higher).
- Basic understanding of Java and networking concepts.
- Compile the
Server.java
file:javac Server.java
- Run the server:
java Server
- The server will start listening for connections on port
8010
.
- Compile the
Client.java
file:javac Client.java
- Run the client:
java Client
- The client will simulate multiple requests to the server.
- Listens on a specified port for incoming client connections.
- Accepts client connections and assigns each to a thread from the thread pool.
- Processes the client request and sends a response.
- Closes the client connection after communication.
- Establishes a connection to the server.
- Sends a request to the server.
- Waits for and processes the server's response.
- Closes the connection.
- Concurrency: Handles multiple clients simultaneously without blocking.
- Efficiency: Reuses threads from a thread pool, reducing overhead.
- Scalability: Supports a large number of concurrent connections.
You can test the server's performance by adjusting the following:
- Number of client threads in the
Client
class. - Size of the thread pool in the
Server
class.
Example:
- Increase
numberOfClients
in the client to simulate a higher load. - Change
poolSize
in the server to observe resource management under varying loads.
This project demonstrates a scalable and efficient multithreaded web server design. It provides hands-on experience with networking, sockets, and multithreading in Java. Thread pools ensure optimal resource utilization, making this implementation suitable for real-world applications.
