| Along with the development of electronic science and computer science, more and more communication network and computer network aggravated together. And the service type network can supply increases quickly. Since the scale of network becoming sweeping together with the increasing complicated network structure, the application model of information technology changed much. It requests stronger ability to the management and application of network. The traditional centralized network management model can't suit the requests of the development of network any more. Network management system needs a stronger, simpler distributing system to manage the baSic function of network through a simple network management workstation.The workflow is the core technology of modeling, optimizing, managements, integrations and automation to business. The network management system becomes complicated more and more along with the sweeping of network scale and the increasing of complexity. It need analyze, define and conformity kinds of service oriented network management process over again. It can increase the quality and efficiency through importing mechanism of management process automatism using standard definition. As the most effective way of process integration, the developing of workflow technology makes the redefinition of network management system in the view of workflow.This thesis begins from the description to network management requirement flow, researches the cosmically distributing and integrated transmission network architectures, analyses the operation process to network management layer mainly. In the view point of workflow technology, this thesis conformity the network services of network management belongs to up layer. And a new service process based on workflow model is defined. Then the north bound interface of network system which is based on workflow is modeled. At last the implementation of CORBA distribution system is given as same as a test system. |
