新一代交換式網際網路路徑器之研製

Abstract

近來隨著電腦技術的進步與網際網路的發展，網路呈現爆炸性的成長。因此，舊有的IPv4所規範的網際網路位址目前已呈現不足的現象。為了解決位址不足的問題，IETF已經提出新一代的網際網路通訊協定(IPv6, IPng)，以128位元的位址空間來取代原來的32位元的位址空間；且在IPv6的協定中更支援未來的行動通訊與多媒體通訊。
針對新一代網際網路的需求，以下一代網際網路通訊協定為基礎研發與設計出交換式網際網路路徑器（Switching Router）的系統，並將此系統實做與測試。本篇論文將敘述交換式路俓器之系統架構、運作流程，並詳細介紹交換式IPv6路由器之位址查詢（Address Lookup）設計。最後將展示實作與測試的結果。Recently with the enhancement of computer technologies and development of Internet, the network traffic explosively grows up. To salve the problem of lacking Internet addresses, IETF has proposed a next generation Internet protocol (IPng or IPv6), which replaces the conventional 32-bit addressing by 128-bit addressing. Moreover, the IPv6 naturally supports the mobility and multimedia communications. In order to accommodate the requirements for next generation networks, this paper design and implement the switch-based IPv6 routers (SIR) systems, and the experimental results will also be evaluated. This paper will present the system architecture and operation flows of SIR. The IPv6 address lookup design will be also emphasize in the proposed SIR systems. Consequently, the implementations and experimental results will also be demonstrated.
