智能配用电网向IPv6过渡将是大势所趋,IPv4向IPv6的过渡将是一个漫长的过程,所以,研究智能配用电网向IPv6过渡的技术和策略非常必要。根据实际情况,可以选择双栈技术、隧道技术、协议转换(NAT-PT)技术等作为向IPv6过渡的技术,关注扩展性、安全性、性能、需求、应用场景与应用阶段等因素。从IPv4向IPv6过渡可以划分为IPv6孤岛、IPv4网络与IPv6网络并存、IPv4孤岛和IPv6网络一统天下等4个阶段。保护既有投资、独立性、组网灵活性、可靠性和稳定性等是过渡策略需要考虑的问题。在整个过渡期间,对于智能配用电网的业务应用系统应注意选择支持双栈的操作系统;对于智能配用电网的终端,应注意域名控制和用户主机的双栈支持;对于智能配用电网的数据传输网络,应注意互通技术。
The transition from intelligent distribution network to IPv6 will be the trend of the times. The transition from IPv4 to IPv6 will be a long process. Therefore, it is very necessary to study the technologies and strategies of intelligent distribution grid to IPv6. According to the actual situation, dual-stack technology, tunneling technology, and protocol conversion (NAT-PT) technology can be selected as the transition technologies to IPv6, focusing on such factors as scalability, security, performance, requirements, application scenarios and application phases. The transition from IPv4 to IPv6 can be divided into four stages: IPv6 isolated islands, coexistence of IPv4 and IPv6 networks, and unified IPv4 islands and IPv6 networks. Protecting existing investments, independence, network flexibility, reliability and stability are issues that need to be considered in transitional strategies. During the entire transition period, the business application system supporting smart grid should pay attention to choosing an operating system that supports dual stacks. For terminals with smart grids, pay attention to dual-stack support of domain name control and user hosts. Grid data transmission network, should pay attention to interoperability technology.
