【正文】 1 IPv4 到 IPv6 的過渡方案設(shè)計 物理與光電信息科技學(xué)院 電子信息工程 專業(yè) 106032020207 江播偉 指導(dǎo)教師 董雪豐 【 摘 要 】 本文簡要 介紹了 IPv4向 IPv6過渡的主要技術(shù) — 雙協(xié)議棧技術(shù)、隧道技術(shù)、協(xié)議轉(zhuǎn)換技術(shù)（翻譯機(jī)制）。對各過渡策略的優(yōu)缺點 進(jìn)行分析總結(jié)以及 IPv6網(wǎng)絡(luò)部署 初期，中期，后期 各策略的 具體 應(yīng)用進(jìn)行了說明。 詳細(xì)介紹了GRE手動隧道 ,IPv4兼容地址自動隧道， 6to4隧道， ISATAP， NATPT 等過渡方案的配置設(shè)計。 【 關(guān)鍵詞 】 IPv4； IPv6； 過渡技術(shù) 2 目錄 1. 引言 ............................................................................................................................. ...............................4 2.
