目前台灣主要使用IPv4網路環境,而IPv6網路環境尚處於實驗起跑階段,因此本研究利用校園網路環境來實作與模擬IPv4與IPv6共存相互通訊方式,以期了解兩者混合運作之特點。實作部分採用Tunneling方式來完成,其利用IPv4網路節點建立IPv6位址介面,來源端IPv6的封包資料封裝上IPv4表頭,經過所建立的隧道,抵達目的端再進行解封裝,還原成IPv6的封包資料,完成IPv6之溝通。模擬部分採用Dual Stack來完成,利用模擬軟體Packet Tracer來建置Dual Stack,使用CISCO 2811路由器來設定IPv6位址及路由,使在同一條網路線上可同時進行IPv4與IPv6通訊。 Tunneling方式實作建置完成後,利用Iperf來進行IPv4與IPv6網路效能之比較,測試內容主要以TCP與UDP通訊協定為主。最後,建置校園IPv6網路應用服務之Web、VsFTP、DNS、Mail伺服器,實現IPv6於IPv4網路環境通訊之目標。
The IPv4 network environment is mainly used over Taiwan. This study implements or simulates IPv4 and IPv6 hybrid network on campus. The implemented network is adopted by the tunneling technology. The simulated network is adopted by the dual stack technology. The IPv4/v6 network performances are examined by the Iperf software in TCP and UDP protocols. The implemented IPv6 network performance is compared with the IPv4 network. Simultaneously, the campus IPv6 network application services of Web, VsFTP, DNS and Mail servers are established, and the IPv4/v6 communication goal is arrived each other.
