What is the network load balancher?

The network is a system of connected things or people. The computer network is a network that consists of computers and their sources such as shared scanners, printers, routers and servers. The network load balancer can be one of two things. For one thing, it may refer to specific Microsoft® technology called Balancing network load (NLB), which was part of the Windows 2000 Server® and Windows server® 2003 and was an option component for Windows Server® 2008. in different ways to perform tasks. The cluster can provide a system of fault tolerance and load leveling. The network load balancer can be used to distribute the load on multiple servers on the network as well as multi -discs in the storage network (SAN), as well as to distribute file protocol requirements on file servers. A transaction that enters the network can be divided on all servers or can be redirected to a server,as available.

One common situation in which the network load balancer is useful is the distribution of a large number of http requirements (Hypertext Transfer Protocol) to various web servers located on the server farm. This prevents any server from overloading. The practice of load balance helps to negate attacks on denial services, the point of which is the overload of the servers.

The network load balancer can be several different things. It can be a software program whose only purpose is to balance the burden. It can also be a hardware device. One hardware device that acts as a network load loader is a multi -layer switch, a device that controls and forwards packet transmission that enters the network.

The

DNS servers are another type of hardware that can be used as a network load and network load. One used technique usedis called Round Robin DNS . In this system, when the DNS request is accepted, the requirements are handed over to servers one by one in a continuous loop. One of the problems with this system is that there is no account for the requirements that each transaction on the server to which it is sent, so it actually works as a distributor than a real balancer, even if the system is overloaded, it will have a balancing effect.
