  1. IPv6路由搜尋演算法的探討 出處：中山大學資工研究所碩士論文 作者：張瑋哲 資碩一 9601 郇智喬

  2. 目錄 • 簡介 • 相關文獻 • Modified Memory Access Algorithm for IPv6 • 模擬及結果 • 結論

  3. 簡介 • IPv4遇到的問題 • IPv4上的routing lookup方法 • Conventional algorithm • Hardware and caching solutions • Protocol based solution • New algorithm

  4. 相關文獻 • IPv4 • IPv6 • 文字表示法：X:X:X:X:X:X:X:X • 例如 ABCD:EF10:2345:6789:0120:0204:0106:1045 • Address type • Unicast :Aggregatable Global , Link-Local , Site-Local • Anycast • Multicast 8bits 4bits 4bits 80bits 32bits

  5. 相關文獻 • Routing Lookup on IPv4 • Dynamic Prefix Trie • Fast Routing Tale Lookup Using CAM • High-Performance IP Routing Table Lookup Using CPU Caching • Routing Lookups in Hardware at Memory Access Speeds • Scalable High Speed IP Routing Lookups • IP Lookups using Multiway and Multicolumn Search • Small Forwarding Tables for Fast Routing Table • Faster IP Lookups using Controlled Prefix Expansion

  6. 相關文獻 • Routing Lookup for IPv6 • Scalable High Speed IP Routing Lookups • IP Lookups using Multiway and Multicolumn Search • Faster IP Lookups using Controlled Prefix Expansion

  7. Modified Memory Access Algorithm for IPv6 • 目前IPv6位址只使用了15% • 位址分段 • Multicast address • Unicast address • 總共切成7段一個RT16 五個RT8 一個RT64 • 分成四種Table RT16,RT8,RT8-end,RT64 • Building Routing Table

  8. 模擬及結果 • Test Pattern Design

  9. 模擬及結果 • Number of Memory Access

  10. 模擬及結果
