BURMAUG / load-balancer-simulation

This program simulates a simple distributed load balancer that routes traffic on distributed servers.

Simple Distributed Load Balancer Simulation

Introduction

This is a simulations of the implementation of the software Load Balancer that routes TCP network calls to different running instances for our radius calculating server in a multithreaded manner.

Enhancements Coming

• Round-Robin routing
• Sticky Round-Robin routing
• Health Checks

Round-Robin

This algorithm is implemented using a local customized linked-list using the next pointer as a needle that points to the next node server as a client request is being executed. If client requests moves the node to the tail node, the pointer routes back to the head. Would be easier to make it a circular linked-list.

Sticky-Round-Robin

Issues

• Faults
• Thread sleeps to avoid collisions
• Probable unnecessary use of locks

Technologies Used

• Java
• Socket and ServerSockets
• Threads using Runnable interface
