What does it do?
Network Load Balancing is a
way to configure a pool of machines so they take turns responding to
requests. It’s most commonly seen implemented in server
farms: identically configured machines that spread out the load for a
web site, or maybe a Terminal Server farm. You could also use it for a
firewall(ISA) farm, vpn access points, really, any time you have TCP/IP
traffic that has become too much load for a single machine, but you
still want it to appear as a single machine for access purposes.
How does it work?
It’s pretty straightforward. After you install NLB on a server, you add
two or more machines to a NLB Cluster. The machines are configured with
2 IP addresses: their own private unique one, and a second one that is
shared by all the machines in the cluster. The machines all run an
algorithm that determines whose turn is next at responding to
requests. They also exchange heartbeats with one another, so they all
know if one server goes down and won’t allocate any more requests to
him. You can have up to 32 machines in a cluster.
You can do some smart stuff with regards to how requests are allocated too. You can set up affinity so that requests from one subnet will be responded to from Server A whenever
You can do some smart stuff with regards to how requests are allocated too. You can set up affinity so that requests from one subnet will be responded to from Server A whenever
possible, and that other subnets prefer Server
B. Maybe you want 80% of all incoming requests to be handled by Server
A, with the rest going to server B. You can do that too
