Assignment3

Performance Tests

Performance test can be executed by running GenericNode/docker_client/performanceTestDistTCP.sh

Set Number of Servers

Number of servers can be set by editing three files below;

• GenericNode/docker_server/DistributedTCP_server/serverlist.cfg (only for the config file tracking method)
• GenericNode/haproxy/haproxy.cfg
• GenericNode/setup_distributedTCP_containers.sh

Set Node Membership Tracking Methods

You can change node membership tracking methods by modifying GenericNode/GenericNode.java.

• TCPServer server = new TCPServer(new ConfigFileGetOtherServersStrategy());

  Distributed TCP servers use a config file to track node membership (enericNode/docker_server/DistributedTCP_server/serverlist.cfg).

• TCPServer server = new TCPServer(new CentralizeMembershipGetOtherServersStrategy());

  Distributed TCP servers track node membership by using a centralized membership key/value store.

Assignment2

Overview

It contains scripts mainly for performance testing of UDP, TCP, and RMI clients.

Project Structure

• GenericNode/executeAllPerformanceTest.sh: This script executes performance tests for UDP, TCP, and RMI clients.

Usage

1. Start the Docker container to call GenericNode/setupAllContainers.sh.
2. Execute the GenericNode/executeAllPerformanceTest.sh script to do performance tests.

Performance Tests

• performanceTestUDP.sh: Executes performance test for the UDP client.
• performanceTestTCP.sh: Executes performance test for the TCP client.
• performanceTestRMI.sh: Executes performance test for the RMI client.
• All of above can be done by calling GenericNode/executeAllPerformanceTest.sh

Each test measures the time it takes for the client to send a request to the server and for the server to respond. The results are measured using the time command and are displayed in three parts: real (actual elapsed time), user (CPU time used in user mode), and sys (CPU time used in system mode).

Class Overview

• UDPClient: This class is responsible for sending and receiving data over UDP.
• TCPClient: This class is responsible for sending and receiving data over TCP.
• RMIClient: This class is responsible for sending and receiving data over RMI.
