Web-based applications are revolutionizing both the features that can be delivered and the technologies for developing and deploying applications. In this paper, we present a web-based load-adaptive network management system framework. Our system is scalable, extendable, modular and based on open architecture. It is also load-adaptive as it can adapt to the increase in the number of incoming Web Service requests so that the systems performance will not degrade under heavy request loads. To evaluate the proposed architecture, we built a multi-tiered web application testbed with open-source components widely used in industry. Experimental studies conducted on the testbed demonstrated the effectiveness of the proposed approach. By developing the platform and making it available to the research community, we hope to catalyze the development of an open source stack for Web-based network management and monitoring.展开更多

An IPv6 network management and operations support system is necessary for real operable NGI. Presently there are no approved standards yet and relevant equipment interfaces are not perfect. A Network Management System (NMS) at the network layer helps implement the integrated management of a network with equipment from multiple vendors, including the network resources and topology, end-to-end network performance, network failures and customer Service Level Agreement (SLA) management. Though the NMS will finally realize pure IPv6 network management, it must be accommodated to the management of relevant IPv4 equipment. Therefore, modularized and layered structure is adopted for the NMS in order to implement its smooth transition.展开更多

The classic centralized paradigm, adopted by SNMP, which was once appropriate in theprevenient phrase, has posed problems with the explosive expansion of networks, as well as othercentralized models. Mobile Agent (MA), owing to its capability of implementing a distributed system,represents a challenging approach to provide network management with high performance. In thispaper we analyze the network management structure model based on MA at first, and then we putforward a reference scenario based on MA and compare it with the traditional model. We also describea prototype implementation based on our mobile agent system named MAS. Finally, we do someexperiments to verify the performance of our framework prototype.展开更多
