在網際網路(Internet)的使用日趨盛行下,各類產業對於網路使用的品質要求也日益提昇,大型區域網路(LAN)的環境中,往往因為過多數量的電腦設備及更開放的自由網路使用下,致使許多因為網路使用問題日益增加,因此對於區域網路內的網路管理更是不能忽視。中大型的企業區域網路,所負擔的是整體企業,包含行政、銷售、產品等的正常運作。以往網路的管理及研究均把焦點集中於廣域網路(WAN)的範圍,近年來由於區域網路內的頻寬(Bandwidth)提昇,流量增加、網路服務型態以及網路攻擊(Network Attack)的型態改變等,都直接衝擊區域網路內的使用效能,為達到更佳的區域網路管理模式,本論文整合現有技術觀念,提昇網路管理系統功能,解決區域網路內所產生的分散式阻斷服務(DDoS)攻擊產生。
With the gradual popularity of the Internet, every kind of industries had increasing demands for the quality of Internet. In a local area network (LAN) environment, due to the exceeding amount of computer equipments and the more open and free access to the Internet, many Internet application problems had been arised accordingly. Hence we can not ignore the Internet management in LAN. A LAN in medium and large size of corporations takes the responsibility of functional operations of the whole corporation, including administrations, sales, and products , etc. In the past, the Internet management and research focused on wide area network (WAN). In recent years, due to the promotion of bandwidth in LAN, the increase of flow, the change of Internet service type, and the change of network attack type, etc, the application efficiency in LAN was directly impacted. In order to achieve a better management model in LAN, this thesis integrates the current technical concepts, enhances the function of Internet management system,and solves distributed
