NLB Cluster

NLB load-balances incoming client IP requests across multiple AgilePoint Servers in the cluster. The AgilePoint Servers in the cluster then concurrently process the different client requests.

NLB Clustering is setup so that each AgilePoint Server in the load balanced cluster is configured with the same Virtual IP address. Whenever a request is made on this Virtual IP, a network driver on each of these machines intercepts the request for the Virtual IP address and re-routes the request based on the load to one of the machines in the NLB cluster.

To implement an AgilePoint Server NLB cluster, a NLB software or hardware device is required. Microsoft offers a low cost, Network Load Balancing Manager software component as part of Windows Server 2003. While Windows Server 2003 provides software network load balancing, an alternative high performance load balancing hardware device may be better suited for production systems.

NLB clustering offers the following benefits:
