Taking an innovative approach to network management, communications protocols, and data networks, this book examines a unique method in which protocols and mechanisms are broken down into simple management tasks. It helps you steer your way through the history of network management and communications protocols, and guides you through the design of new protocols and the construction of complex networks operating under a simpler paradigm. Here you will find a new model for network management wherein various data communications protocols and mechanisms are easily handled as basic management tasks, thereby reducing expenditures of time, effort, and resources. The author uses a bottom-up approach and avoids rigorous mathematical devices to apply a new network control theory to all the layers you encounter in network planning, design, and management.
