Mobile Agent Technology Applied Research In The Nms And The Partial Implementation

As the remarkable development of computer network technology, Internet has come to pervade every aspect of our lives and society, and play more and more roles. Especially, as the maturation and applications of IPv6, WLAN and VoIP, new direction has come forth in computer network. On one hand, network unceasingly extend in a wider scope, and its complexity upgrade to a higher grade or standard; On the other hand, network has embodied a higher derivatives, and put forward a higher demand for flexibility and expansibility. The weightiness of network management has increasingly enhanced, because it has become the important part in network system. Network management system plays an important role in high efficiency and providing satisfactory service to consumers. At the same time, the development of network management system gradually becomes a decisive factor in evolution of network technology. Recently, most of network management systems are based on simple network management protocol (SNMP). Traditional network management of SNMP, however, is based on Manage/Agent(Server/Client) model, which presents a host of disadvantage to completeness, flexibility and scalability. Especially, the centralized network management mode gradually can't meet the demand to network when the scale of network as extended at a striking speed. As a potential agent technology, mobile agent technology has a characteristic of mobility and aptitude, and its combine with network management technology can remarkably increase flexibility and scalability. This technology has a fundamental improvement in contrast with traditional centralized SNMP network management. At first, this paper reviews the development history of network management technology, and introduced research in this domain. In the second chapter, interrelated content of network management is presented. Mobile agent technology is introduced in the third chapter, and at the same time, the concept, fundamental, characteristic and standardization are presented. In addition, some principal mobile agent platforms are analyzed. The forth chapter research the application of mobile agent in network management system, and the Aglet platform is discussed. The implement of network management system module based on mobile agent is presented in chapter5, which comprise a system implement to Ipv6 based on mobile agent. In the last part of this paper, by contrast with traditional centralized SNMP network management, summarization and evaluation about system response time and network flux cost are accomplished.
