Enhancement of Network Administration through Software Defined Networks

Abstract
Abstract: Now a days organizing the Network is very complex and challenging issue. To control, manage, and to provide a secure communication network, network managers must grapple with low-level vendor-specific configuration to implement complex high-level network policies .Most of the previous proposals to make networks easier to manage, many solutions to network management problems amount to stop-gap solutions because of the complexity of changing the underlying infrastructure. The rigidity of the underlying infrastructure presents few considerations for innovation or improvement, since network devices have generally been closed, proprietary, and vertically integrated. A new approach in networking, software defined networking (SDN), suggests separating the data plane and the control plane, making network switches and routers in the data plane simple packet forwarding devices and leaving a logically centralized software program to manage the behavior of the entire network. SDN introduces new possibilities for network management and configuration methods. In this paper, we identify problems with the current state-of-the-art network configuration and management mechanisms and introduce mechanisms to improve various aspects of network management. We focus on three problems in network management: first one enabling frequent changes to network conditions and state, second providing support for network configuration in a highlevel language, and third providing better visibility and control over tasks for performing network analysis and troubleshooting.
