[[alternative]]A Study on Application of DirecPC Extranet

碩士商業教育學系[[abstract]]隨著網際網路應用的普及，以及電子商務的興起，促使企業建置商際網路(Extranet)來當作經營工具，期望能帶來更多的商機，以提昇企業本身的競爭力，然而，頻寬不足、網路安全問題是影響國內企業建置商際網路(Extra-net)的最大原因。國家基礎建設(NII；National Information Infrastructure)「三年三百萬網際網路用戶」計畫已於去年年底達成，在網路頻寬早已不敷使用的情況下，造成網路塞車情況日益嚴重，進而影響到企業應用Extranet的意願與效率。 有鑑於未來的網路架構將以寬頻網路應用為主軸，故本研究探討企業如何運用以衛星直播系統為基礎的商際網路(Extranet)應用之考量與效益，並找出未來的發展趨勢及應用層面，以作為企業及學術界研究之參考。[[abstract]]The popularity of Internet and the spread of Electronic Commerce urge current enterprises to build Extranet as a business tool that is expected to bring with more business chances for increasing enterprises’ competitive advantage. Nevertheless, the insufficiency of bandwidth and the network safety are the major problems for building Extranet in enterprises in Taiwan. The plan of “Three-Year-Three-Million Internet users” in National Information Infrastructure had been achieved last year (1998). At the same time, the communication of network was seriously clogged up under the insufficiency of bandwidth and too many users. This had negative influence on the efficiency of Extranet and the willingness of enterprises to build Extranet. The application of wide-band network is the future trend, so this study focuses on how to use DirecPC Extranet in enterprises. This study investigates the application and effectiveness of DirecPC Extranet in enterprises and then finds out the future trend and the application level for the reference of enterprises and academic research
