Research And Application Of Electrical Data Dedicated Network Based On IPv6 Technology

Power dedicated data network is important to the power system's internal data communication, which is related to the operation of power system stability and reliable electricity supply. Therefore, its security and reliability requirements are high.IPv4 protocol is currently the mainstream of computer network protocols, also used in the power dedicated data networks. IPv6 as a new version of IP protocol, designed to solve the problems inherent in IPv4. it is not completely abandon IPv4, but rather on the basis of inheritance compatible with innovation, from IPv4 to IPv6 is not overnight, but a gradual process of evolution.Based on the status of××Grid data communications networks, research for the existing business systems of××Grid and networks can be used to carry the network transition to future technologies, transition strategies and the transition method, taking into account the network during the transition network management, network security and other kinds of other problems.This article focuses on include: management information systems of business, production management business systems, business systems, internet system transition technology, integrated data network, scheduling and data networks and local area networking technology transition strategy.Technology emphases include: dual stack technology (Dual Stack), tunneling (Tunnel), IPv4 and IPv6 translation technology, 6PE technology, OSPFv3 technology, BGP4+ technology, IPv6 network management and security technologies, as well as the transition process in the network transition to the principles of a variety of network applications.The research of the transition from IPv4 to IPv6 technology in Power dedicated data network is the key part of this research project. The conclusions will be used to guide××Grid data network transition from IPv4 to IPv6, and also be significance to the next power-specific data network construction and expansion.
