Design And Implementation Of An Accounting System With IPv6 Network

As a protocol for network of the next generation, IPv6 has been better improved in security,expansibility and quality compared with IPv4. Due to the rapid development and huge technological advantages of IPv6,the development of network accounting system has become increasingly important. This paper will mainly discuss one type of the network management based on IPv6—the whole process of designing and implementing the accounting management system. Due to the many technological differences between IPv6 network and IPv4 network, their accounting systems are greatly varied, especially in a transitional period from IPv4 to IPv6 when the network accounting problem arises in all kinds of complicated cases. All the above-mentioned factors will be the main problems this paper is to discuss and solve.In the first part,the paper mainly focuses on the content of IPv6 protocol,the general content of the Simple Network Management Protocol SNMP and related problems concerning the realization of SNMP in IPv6 environment. Then,the paper introduces the functional outline and designing plan of IPv6 network accounting system,especially the accounting methods based on users through authentication when the system deals with the problem of automatic distribution of IPv6 sites and the operation methods of data-collecting problems in a IPv4 and IPv6 combined environment. In the end,the paper introduces such implementation methods of the system as the system's structural modes,the implementation methods of the accounting modules and the selection and designing of its database.The design and implementation of this system selected a Windows platform as its base,so that the accounting function of SNMP in an IPv6 environment is achieved. The system played a full accounting of the SNMP management advantages: good performance; based on user fees; common good; low cost; easy upgrade from IPv4 to IPv6,so that it not only proved the feasibility of this system,but also paved the way for designing and implementing other network management based on IPv6.
