摘要: | 網路會議(Networking Conference)系統除了需滿足即時性影音資料的傳輸及其相關支援技術之外,還有一個相當重要的特性便是達到遠端協同合作(Remote Collaboration)的目標。Remote Collaboration功能性上可區分為鬆散性協同合作(Loose Collaboration)及緊密性協同合作(Tight Collaboration)。前者即為透過某些單一應用程式作一些特定的交流,如遠端白板系統、聊天室、網路遊戲等。後者則為多方的會議參與者可同時實際控制一個或多個遠端電腦,並將結果畫面即時廣播/分享給其它的參與者。如VNC(Virtual Network Computing)的server console mode,微軟建構於遠端桌面協定(RDP; Remote Desktop Protocol)之上的遠端協助(Remote Assistance)。此種方式能充分讓所有會議參與者於彼此電腦裡的所有程式、檔案及其它資源之間,達到最完整的控制、分享與交流之目的。由於RDP採用GDI (Graphics Device Interface) information之設計,因而更能節省整體資料的傳輸量。基於上述之需求,本論文提出一個架構於Remote Desktop Protocol之上,並可達成緊密性協同合作目標的遠端協同合作網路會議架構(Remote Collaboration Framework for Networking Conference),整體架構包含一個可達到Tight Remote Collaboration目標的RDP Gateway系統,一個以RDP封包為基礎的動態會議記錄,並能提供重播會議功能的系統,以及一個協助會議控制進行的Conference Control Manager系統。不僅能提供網路會議系統所需之完整遠端協同功能,亦可滿足高效率之資料傳輸需求。 A networking conference system should provide not only the technology of real-time video/audio data transmission, but also an important functionality, the remote collaboration. Remote collaboration can be categorized as loose collaboration and tight collaboration. The loose collaboration means that all participants can only communicate by some specific applications such as remote whiteboard, chat-room, cyber games, and so on. In the other hand, the tight collaboration indicates that some participants can actually control one or more remote desktop of some other participants, and share the same controlled desktop results to all participants. For example, the VNC(Virtual Network Computing) server console mode, and the Microsoft Remote Assistance which is designed based on its RDP(Remote Desktop Protocol) are tight collaboration systems. The purpose of tight collaboration is to let each participant can have complete control rights to control another one’s desktop, accessibility and sharing of all applications, data, files and other resources among all participants to achieve the goal of full controllability, accessibility and sharing. Especially, the RDP can reduce much more amount of rendering data due to the GDI (Graphics Device Interface) design it adopts. Therefore, according to the demands mentioned above, this dissertation proposes an efficient remote collaboration framework for networking conference based on the remote desktop protocol. The proposed framework consists of a RDP Gateway with remote tight collaboration functionalities, a conference minute system by logging RDP packets as the conference minute which can be replayed, and a conference control manger to facilitate the conference control. It provides not only the full functionalities of remote collaboration, but also concerns about the efficiency demand of rendering data transmission that a conference system needs. |
