Control Theory and Practice Strategy of Network Load Balancing

Network load balancing(NLB) technology uses distribution algorithms to distribute the access traffic for servers in the cluster,and when a cluster of server fails,NLB would automatically forward data to other available server. Load balancing is completed by multiple servers symmetrically forming a collection of servers,each server is of equivalent status,and could independently provide services without the support from other servers. Through a load-sharing technology,the requests from outside would be uniformly assigned to a server in the symmetrical structure,and the server,according to the received requests,independenty responds the customer's requests. The load balancing technology could equally distribute the customer's requests to the server array,thus providing rapid access to important data and solving numerous problems of simultaneous access services.
