在理論上存在三類方法檢測堆棧溢出：不允許用超長的輸入參數覆蓋返回地址；允許返回地址被覆蓋，但不允許控制流轉向非授權的用戶；允許控制流轉向非授權的用戶，但不允許其可執行代碼被運行。As a result, it is no need for the endpoints to maintenance any system control task. in this article we propose a compactness coupling conference system architecture, and at the same time we analysis the system key techniques, giving a part of flow chart and pseudocode as examples. main content are given as below : how to use direcshow technique to obtain multimedia data ; multimedia data transport over ip network ; multicast principal and application in the system ; packing and unpacking rtp / rtcp packet so as to control network flow and in this part we introduce spillage arithmetic ; as the core part of the system, conference control and management are the main concern in our design
323框架基礎上提出緊耦合式會議系統體系結構，並以c s結構作為實現模型；本文對會議系統的中心mcu流程進行分析設計，並建立數據結構；該部分還涉及到對各個資源的調度；為了對會議控制有更好的理解，用petri網描述了會議控制會議管理的過程並提出了靈活的授權管理機制；對服務器端的數據通信設計了多播通信的實現方案；本文簡單回顧了directshow技術的應用，並在此基礎上實現了多媒體數據的採集和回放；為實現多媒體在網路上實時傳輸選擇不可靠傳輸協議udp ，為使數據能正確回放，採用了rtp和rtcp協議。
