摘要:	近年來，分散式阻斷服務攻擊的威脅性不斷增加。然而，目前對分散式阻斷服務攻擊尚未有一套完善的方法，能夠在轉移服務時同時保持連線，並即時將新連線導向新的目標。在本研究中，將基於一套可能夠在轉移服務時同時保持連線的系統上，提出一個能即時將新連線導向新的目標的方法，進一步提升在分散式阻斷服務攻擊發生時，受該系統保護的服務的存活性。在此篇論文中，我們將會簡單的介紹我們的動機與目標，接著介紹我們所使用的基礎系統。接著我們會介紹加入了新機制的系統的運作概念與系統架構。然後講述實作的細節。最後是效能的分析與討論。 ;In recent years, Distributed Denial-of-Service (DDoS) attacks have become more and more threatening. However, there has not been a perfect methodology can keep connections alive during migrating services, and permit new connections to new host immediately at the same time. In this work, we based on a system that can keep connections alive during migrating services then propose a new mechanism to permit new connections to new host immediately, and thus improve the service availability during DDoS attack. In this thesis, we will talk about our motivation and purpose. Then we will introduce the base system we are going to use. After that, we will present the principle of Migmod, its system structure, and implementation details. At the end, we will discuss the performance evaluation and future works.
