1. NETWORK LOAD BALANCING (NLB) Microsoft Windows Server 2003 By Mohammad Alsawwaf ITEC452 Supervised By: Dr. Lee RADFORD UNIVERSITY

2.  Network Load Balancing (NLB) is a Clustering Technology.  Windows Based. (Windows Server 2003).  To scale performance, Network Load Balancing distributes IP traffic across multiple cluster hosts. It also ensures high availability by detecting host failures and automatically redistributing traffic to the surviving hosts.  NLB provides remote controllability. INTRODUCTION

3.  Setting up NLB on the machines and testing that it is working. OBJECTIVE

4.  When a client requests a service from the main server, the server consults the cluster and check which host is open for traffic without pressuring any specific host.  When it finds an open server, it will redirect the request to that host to be completed.  If the main host was busy, the second prioritized host will complete the job.  In case of heavy traffic on all hosts, the load will be distributed equally to all hosts. HOW IT WORKS
