Research And Design Of Universal Gateway Model Based On Policy And NETCONF Management

With the fast development of computer network especially the internet, the scale of the network is expanding increasingly, and network complexity is strengthening continuously. Traditional network management protocol such as simple network management protocol (SNMP) has not satisfied the requirement of network management, the new network configuration protocol (NETCONF) appears as a result. NETCONF based network management is considered as the efficient candidate of the traditional network management for its many merits. It is very meaningful to do research on the NETCONF era, which makes us follow the step of international network management era and quickly go into the foreland of network management research.However, the research of NETCONF based network management is in the developing phase now, most equipment trader still support traditional network management interfaces such as SNMP, TELNET. Therefore, how to realize the compatibility of NETCONF based and traditional network management is a key problem to be solved. Nowadays, a universal gateway automate translating multi-protocols is extraordinary needed in the network management era. This paper is just doing research on the universal gateway model on translating multi-protocols, according to the foreground and application requirement of next generation network management.In this paper, after a whole introduction to the architecture, protocol operations, information model and communication mechanism to SNMP and NETCONF based network management model, a universal gateway model based on policy and NETCONF is proposed. Compared as the simple gateway, this gateway has the characters of uniform translation, flexible translation and expansibility. Taking policy based configuration system, user-defined configuration and automately adaptation according to protocol formats are realized; taking the communication mode of SOAP based on HTTP, co-operation among the isomerous applications and platforms are easily implemented, which makes the application accessed by widely uses. Another, as to the special requirement of next network management, network management information base (MIB) is improved, and a translation scenario on MIB of NGN and traditional network management is proposed. At last, a detail scheme of implement the gateway model is expatiated.
