第七章 結論與未來工作

7.2 未來工作

我們的目標是希望可以發展一套整合核心行為與網路協定行為的網路通訊 裝置之評比工具,而本論文已經成功將嵌入指令於核心系統的動作自動化,並且 成功將核心行為記錄與網路協定行為記錄作對應。

可是核心行為記錄與網路協定行為記錄過於龐大,因此我們還需要一種智慧 型的診斷工具,從龐大的記錄之中,找出影響網路效能的原因,進而針對原因提 出建議等等。

未來診斷工具更可以配合核心事件的記錄,找出因為某些特定網路封包,造 成核心系統的狀態改變,如:ARP 封包會造成 ARP Table 的改變,DHCP 封包會 造成網路卡介面的 IP 改變,藉此開發者可以更加詳細剖析暨除錯網路通訊裝置 的整體通訊行為。

更可以修改本論文的選擇性指令嵌入技術,使之運用於各種核心系統,並且 持續改進以配合核心系統的演進。另一方面,由於本論文只針對乙太網路設計封 包關聯技術,並未針對其他類型的實體網路,因此未來可以修改封包關聯技術來 達成剖析暨除錯其他類型的實體網路。
