This system often have some problems which are if one of servers has any breakdown, network services running on this server will not run, and some of servers which undertake important network services will run over load while others are still having many resources (., CPU, memory etc), but cannot share. Load balancing program for network services is a new load balancing program for ISPservers system. Index Terms—Network, Grid Computing and Load Balance Computing, − Distributed I. INTRODUCTION L OAD balancing is the process of distributing some load across multiple links, servers, processors, or other devices in order to repair overload, improve performance and overcome deficiencies in existing equipment. Nowadays there are a lot of common load balancing methods such as the sever load balancing, DNS-based load balancing, firewall load balancing, and global server load balancing. − Server Load Balancing (SLB) is a process that distributes traffic of a site among several servers using a networkbased device. − DNS-Based Load Balancing is based on technology of SLB. DNS operates also “round robin” principle and uses a function of DNS that allows more than one IP address to associate with a hostname. − Firewall Load Balancing (FWLB) has been developed to get the better of the limitations of firewall technologies. Most firewalls are CPU-based, such as a SPARC machine or an x86-based machine. Because the processor is limited, the amount of throughput a firewall is often limited, .
