| 摘要: | 本研究是針對於VoIP中之SIP協定進行詳細探討與說明，並以NS2進行模擬分析。此外，由於VoIP之安全性議題亦為影響其普及之主要因素，其中DDoS攻擊更已成為VoIP網路安全領域最為嚴重的問題之一。所以本研究對各式攻擊以NS2進行模擬分析，並進一步探討在DDoS攻擊之下各種Queue之間對於攻擊的承受能力之比較。
This study is focus on SIP of VoIP, and simulated and analysised by NS2. In addition, because of the security issues are the main factor to affect its popularization, and the DDOS attack has become one of the most serious issues in the VoIP network security. Therefore this research carries on the simulation analysis to various types attack by NS2, and further discusses under the DDoS attack between each kind of Queue regarding the attack comparison of bearing capacity. |
