Comparative Analysis of Different Protocols to Manage Large Scale Networks

In recent year the numbers, complexity and size is increased in Large Scale Network. The best example of Large Scale Network is Internet, and recently once are Data-centers in Cloud Environment. In this process, involvement of several management tasks such as traffic monitoring, security and performance optimization is big task for Network Administrator. This research reports study the different protocols i.e. conventional protocols like Simple Network Management Protocol and newly Gossip based protocols for distributed monitoring and resource management that are suitable for large-scale networked systems. Results of our simulation studies indicate that, regardless of the system size and failure rates in the monitored system, gossip protocols incur a significantly larger overhead than treebased protocols for achieving the same monitoring quality i.e., estimation accuracy or detection delay.
