Corba, Web-based Network Management Framework

Today, the network is growing rapidly and is becoming service-driven network. In this network, the managed resources (which can indifferently be applications, devices, services or network policies) appear, move and disappear across the network, as they are created, installed, activated and used at a pace never experienced before.Such challenges can hardly be met by current management technologies. Current network management framework (e.g. SNMP) follows the manager-agent model. This centralized paradigm has been stretched to its limits by the growing scale and complexity of network systems.The aim of this article is providing a new network management framework. The framework provides distributed computing, intelligent devices, high efficient management, flexible structure for service-driven network.This thesis analyzes the disadvantages of SNMP framework and its manager-agent model. It centralizes the monitoring, analysis, and control of network devices to platforms and leaves to the device agents merely the role of collecting and reporting growing amounts of raw instrumentation data. As networks grow larger and involve more complex elements, the amount of operational data that must be monitored and processed increase dramatically. Management scalability is bound by the rates at which operators can handle data and alerts. As more data is collected and processed, consoles become flooded with unimportant and/or redundant information. In new peer-to-peer management model, management functions are divided into global functions and local functions. And local functions are embedded in devices so that they become intelligent, self-managed devices on some degree.CORBA-, web-based network management (CWNM) framework is...
