Research And Implimentation Of The Network Management System Of The Information Appliance Based On SNMP

With TCP / IP protocol widely applied, especially the development and popularization of Internet technology, embedded devices connecting the Internet becomes an inevitable trend. As various equipments of family network are made in different manufacturers, using different hardware, software technologies and standards, and the understanding of concept of Information Appliance may be different, it will lead to compatibility problem.How to combine the products of information appliance made in various corporations, and achieve the reliability and real-time of network transmission, with its effective management are the main problems which home network has to solve currently. We make use of home gateway to solve this problem, but the actual home gateway is too expensive, its compatibility to various corporations which produce information appliance is not good, it' s bad for the generalizing of information appliance. Embedding the network management software agents in the information appliance network, managers can control and monitor information appliance remotely through network, at the same time, they can construct and maintain the home network to substitute some functions of home gateway. Managing the home network devices has become a new topic in the field of network management.Aimed at this trend, this task makes a further study and discussion in the home network system of information appliance, and makes use of modern embedded network management technology to manage the intelligent home appliances. To comparing with the traditional network management model, it discusses the Network Management Agent and Technology in detail, which are cured in the limited resources and computing power of information appliances. SNMP, because of its briefness, easiness to achieve, maturity in the field of network management technology, becomes the main subject of choice. By making research in the major theories in the information appliance architecture, the function and architecture of home gateway, the information appliance network management model and its comparison with the traditional network management model, and the SNMP protocol and its application in information appliances and so on, the topic proposes and designs a SNMP network management Agents of information appliance, and constructs the family network management system platform of information appliance based on the Management Agent. The management platform is based on SCM SX52, using the extension of external hardware circuit and virtual periphery and virtual network protocol software module, and simulates and achieves information appliance network management by B/S and C/S mode respectively, it can complete the function of traditional network management, and carries out some functions of home gateway. It makes the limited resources of information appliance be a stable network performance, accesses to manage and monitor real-timely in the information appliance which is online. It provides an experimental platform for researching home gateway and inner architecture of information appliance with their function distributing. It enables information appliance step into ordinary families.
