Implementing Network Load Balancing

What Is NLB?

NLB is a scalable, high availability Feature, you can install all versions In Windows Server 2012. Scalable technology is that you Additional components can be added (in this case additional cluster nodes), to meet the growing needs. A node in Windows Server 2012 NLB cluster is a computer, whether physical or Virtual, running on Windows Server 2012 operating system.

In Windows Server 2012 NLB cluster You Nodes between 2 and 32. When you create a NLB cluster, it creates a virtual network address, Virtual network adapter. Virtual network adapter has an IP address and a Media Access Control (MAC) Address. Network traffic to this address evenly distributed across the nodes in the cluster. In a major NLB configuration, each node in the NLB cluster will be in the service which is roughly equivalent to the required speed in all other nodes in the cluster. 

When the NLB cluster receives a request, it forwards the request to the current node using the least. You can configure the number of nodes N LB priority over others.

NLB failed perception. This means that if one node NLB clusters offline requests will be forwarded to the node, the other nodes in the cluster but will continue to receive Request. When the failed node returns to service incoming requests are redirected to transportation All cluster nodes to balance.
