【摘要】 电力专用数据网是电力系统的内部数据通信网络,关系到电力系统的运行稳定和电力供应的安全可靠,是专用的重要数据通信网络,对网络安全性和可靠性的要求很高。IPv4协议是目前计算机网络的主流协议,电力专用数据网络主要采用IPv4协议。IPv6作为IP协议的新版本,旨在解决IPv4固有的问题,它不是完全摈弃IPv4,而是在继承兼容基础上的革新,从IPv4到IPv6也不是一蹴而就,而是一个渐进演变的过程。本文基于某电网数据通信网络现状,研究针对某电网现有各个业务系统及其承载网络未来可采用的网络过渡技术,过渡策略以及过渡方法,同时考虑网络过渡过程中的网络管理、网络安全等各种其他问题。本文主要关注的内容包括:管理信息类业务系统,生产管理类业务系统,互联网类业务系统的系统过渡技术,综合数据网,调度数据网以及局域网的过渡组网技术及策略。技术关注重点包括:双协议栈技术(Dual Stack)、隧道技术(Tunnel)、IPv4和IPv6的翻译器技术、6PE技术、OSPFv3技术、BGP4+技术、IPv6网管及安全技术、以及在网络过渡过程中各种网络应用的过渡原则。电力专用数据网从IPv4向IPv6的过渡技术研究,是某电网公司IPv6技术研究项目的关键部分,其研究成果将用于指导某电网公司数据网络未来由IPv4向IPv6过渡,对今后的电力专用数据网络建设及扩容具有指导意义。更多还原

【Abstract】 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.更多还原
