摘要

下一代互联网协议IPv6已经引起了越来越多的关注。未来IPv6路由表的特性在路由器架构和网络设计中起着关键作用。为了设计和分析高效且可扩展的IPv6 IP查找算法,需要使用IPv6路由表。对现有IPv4表的分析表明,存在一个与随机分布有很大不同的底层结构。由于目前使用IPv6的用户很少,目前IPv6表的大小很小,不太可能反映未来IPv6网络的增长。因此,随机生成的表和当前的IPv6表都不是很好的分析基准。IPv6路由器的开发需要更多具有代表性的IPv6查找表。通过对当前IPv4表的分析,提出了生成IPv6查找表的算法。由建议的方法生成的表显示了真实查找表的某些特征,不仅反映了新的IPv6地址分配方案,还反映了IPv4表的常见模式。随着IPv6得到更广泛的部署,这些表格通过更好地表示未来的查找表提供了有用的研究工具。

Non-random generator for IPv6 tables
The next generation Internet Protocol, IPv6, has attracted growing attention. The characteristics of future IPv6 routing tables play a key role in router architecture and network design. In order to design and analyze efficient and scalable IP lookup algorithms for IPv6, IPv6 routing tables are needed. Analysis of existing IPv4 tables shows that there is an underlying structure that differs greatly from random distributions. Since there are few users on IPv6 at present, current IPv6 table sizes are small and unlikely to reflect future IPv6 network growth. Thus, neither randomly generated tables nor current IPv6 tables are good benchmarks for analysis. More representative IPv6 lookup tables are needed for the development of IPv6 routers. From an analysis of current IPv4 tables, algorithms are proposed for generating IPv6 lookup tables. Tables generated by the suggested methods exhibit certain features characteristic of real lookup tables, reflecting not only new IPv6 address allocation schemes but also patterns common to IPv4 tables. These tables provide useful research tools by a better representation of future lookup tables as IPv6 becomes more widely deployed.
