	Web Farming with the Network Load Balancing Service in Windows Server 2003
		The Network Load Balancing Service has been around in one incarnation or another since Windows NT SP4, but Windows Server 2003 is the first operating system that brings this service into the forefront as a main component of the OS.
		For many companies this feature of load balancing is often important for peace of mind both in the knowledge that a single point of failure on the Web Server is avoided as well as providing an in place mechanism to grow the application should the need arise at a later point.
		Whenever a request is made on this virtual IP a network driver on each of these machines intercepts the request for the IP address and re-routes the request to one of the machines in the Load Balancing Cluster based on rules that you can configure for each of the servers in the cluster.

	Balancing network - Wikipedia, the free encyclopedia
		In a hybrid set, hybrid coil, or resistance hybrid, balancing network is a circuit used to match, i.e.
		A balancing network is required to ensure isolation between the two ports of the four-wire side of the hybrid.
		A balancing network can also be a device used between a balanced device or line and an unbalanced device or line for the purpose of transforming from balanced to unbalanced or from unbalanced to balanced.

	Load Balancing Technologies - Clusters (Site not responding. Last check: )
		Network traffic load balancing is the process of examining the incoming traffic to a cluster and distributing the traffic to each of the nodes for processing as appropriate.
		Load balancing network application services require the software to examine the current load of each node and determine which nodes are able to take on new jobs.
		Even if the network load balancing system is well defined and rigorously implemented, the load will not necessarily be distributed evenly because in the network load balancing situation, the current load on the nodes is not considered, but assumed to be relatively equal because of the statistical fairness of the workload allocation algorithm.

	Appendix B - Network Load Balancing Technical Overview (Site not responding. Last check: )
		Network Load Balancing should not be used to directly scale applications, such as Microsoft SQL Server (other than for read-only database access), that independently update inter-client state because updates made on one cluster host will not be visible to other cluster hosts.
		Network Load Balancing tracks TCP connections on each host, and, after their current TCP connection completes, the next connection from the affected clients will be handled by the new cluster host; UDP streams are immediately handled by the new cluster host.
		Network Load Balancing assumes that a host is functioning properly within the cluster as long as it participates in the normal heartbeat exchange among the cluster hosts.

	bpBallBalancing
		If the neural net controller fails to balance the ball (for example, if the ball rolls off the edge of the beam) then the crash noise is sounded and the ball is given a new random initial condition, and the neural net controller tries again.
		For example, for the neural net to balance the ball, the network must be able to generalize; that is, on the basis of the training data construct a control law.
		Given a second chance at training the network, the student balances the ball in a way that is more suitable for the machine learning process, usually resulting in a more successful neural net controller.

	Artificial intelligence network load balancing using Ant Colony Optimisation - The Code Project - C# Algorithms
		Circuit-switched networks rely on a dedicated connection from source to destination which is made once at start-up and remains constant until the tear-down of the connection.
		An ant is placed on a network of 4 nodes with the source node of 1 and destination node 2.
		Since the network is non adaptive, the pheromone tables are biased towards nodes that are have been taken offline and subsequently being continuously redirected and taking longer journeys every time.

	How To Configure Network Load Balancing Parameters in Windows Server 2003
		NOTE: When you are using Network Load Balancing Manager, you must be a member of the Administrators group on the host that you are configuring, or you must have been delegated the appropriate authority.
		If you are configuring a cluster or host by running Network Load Balancing Manager from a computer that is not part of the cluster, you do not have to be a member of the Administrators group on that computer.
		If you are working from a computer that has a single network adaptor that is bound to Network Load Balancing in Unicast mode, you cannot use Network Load Balancing Manager on this computer to configure and manage other hosts because a single network adapter in Unicast mode cannot have intra-host communication.

		There are two important aspects of load balancing as it applies to VisNetic MailServer, the first is the routing of traffic to the server cluster and the second is the configuration of VisNetic MailSever within the cluster.
		Network Load Balancing presents a common virtual IP address for the entire cluster and transparently partitions client requests across the servers in the cluster.
		Network Load Balancing is implemented using a network driver that is logically placed between the higher-level protocol TCP/IP, and the network adapter of the host.

	Networking - Setting Up Network Load Balancing on Windows 2000 Advanced Server
		Network load balancing is a service that comes with Windows 2000 Advanced Server (not plain old Windows 2000).
		The Network Load Balancing service is unlike other popular load balancing schemes like Red Hat Advanced Server (Piranha) or Big-IP, because it doesn't have a single server that routes the requests.
		Persistence is when the load balancer keeps sending requests from a particular host to a single server in the pool.

		Although with load balancing you may think you want to have 50% of traffic go between the servers and load balance each request, in reality, it's not bad to have a 52% 48% load balance where the sessions are sticky and the users maintain the same server throughout their session.
		Had you had both with all requests load balanced, it would be.
		We saw a lot of our network perf issues work themselves out by simply having front end NICs which took end user traffic with the second NIC being used for communication to the SQL server, and having server to server communication go over that NIC.

		The statistics of the network delays are estimated experimentally and used in the analytical model to show the effect of the balancing instant and gain on the overall completion times of various workloads.
		This paper focuses on £xing the number of balancing instants and optimizing the completion time over the strength of load balancing, which is controlled by the so-called gain parameter, and the time when the balancing is executed.
		This interplay between the strength of load balancing and the magnitude delay has a direct effect on the performance of the policy and on the sensitivity to the selection of the balancing instants.

	How to Configure Windows Network Load Balancing for pure Terminal Server environments
		Network Load Balancing works by assigning a single virtual IP address to those multiple servers that can respond.
		Under the hood, Network Load Balancing enables all of the configured nodes on a single subnet to detect incoming network traffic for the cluster's virtual IP address.
		Then, all incoming packets are received by all servers in the cluster, and each server’s NLB drivers are responsible for filtering which packets are for that server and which are not.

		When IP was in its infancy, network concerns were focused at Layers 2 (data link) and 3 (network) of the Open System Interconnection (OSI) model.
		By definition, this layer was intended to provide network support services for application and end-user processes - addresses and QoS are identified; authentication, constraints and privacy security issues are addressed; network services for file transfers, e-mail and so on are invoked.
		In practice, network service domains blur with IT domains, both lack inter-layer coordination and, in the eyes of some network vendors, actually can subsume or override the service layers of an IT architecture.

	Balancing Network Request Loads
		The value of this parameter is a number that is added to the load for remote queues, so the remote queues appear to have more work than they do.
		As a result, even if load balancing is turned on, local requests are sent to local queues more often than to remote queues.
		This decision overrides any load balancing considerations, because the local server is known to be available immediately.

	Fault Tolerant Load Balancing Consultants - Cisco DistributedDirector Consulting - California, San Francisco Bay Area
		In situations where a single server or cluster can’t provide the throughput required for a critical application, load balancing of multiple servers offers a solution that not only enhances performance but, as a natural byproduct, provides fault tolerance by working around failed servers in a load-balanced farm.
		Load balancing can provide greatly improved operational reliability because failed servers are transparently removed from the resource farm, thus making such failures nearly invisible to users.
		Once you have established a base architecture for a load balancing environment, you have cleared the way for future growth and scalability because adding additional resources to the server farm is a seamless process.
