Network management assures that the network operates efficiently at all times. Network management is the process of controlling a complex data network so as to maximize its efficiency and productivity. Since communication networks have reached a high level of complexity, their management is more difficult to be performed. The international standardization has simplified the study by adopting five principal functional cooperating areas: configuration management, fault management, security, management, performance management and accounting management. The configuration management deals with the setting, changing and restoring network device like bridges, routers, switches, and links etc.
