設計一個快速的資訊傳輸架構改善企業M化之效能

Abstract

由於無線科技的進步與行動裝置應用的普及，企業M化不僅提升企業營運效率同時也是二十一世紀企業競爭力的重要指標。而如何建置暨安全又快速的資訊傳輸架構是企業M化成功與否最重要的因素。 目前企業M化普遍以SSL-VPN為企業資訊傳輸架構的應用環境中，雖然可提供企業行動工作者在企業外部安全的存取企業資訊，但是，由於SSL-VPN不支援PDA行動裝置、不支援登入即認證式之非Web化資訊系統運作模式(此類系統佔企業資訊系統約70%)、意外訊號中斷後原資訊系統無法持續運作等缺點以及行動裝置連線的頻寬需求要高、行動裝置之CPU執行速度要快、儲存記憶體要大等行動環境因素，造成行動工作者無法即時取得的企業資訊，進而影響企業競爭力。 因此，本研究提出一個以終端機服務之資訊傳輸架構雛型，藉由終端機技術(Terminal Technoloy) 之集中式運算處理能力、終端設備硬體需求低、資訊傳輸量小、受訊號中斷影響小等特性解決SSL-VPN傳輸架構的缺點，同時經由實作驗證所提架構之正確性。 本研究顯示以終端機服務為資訊傳輸架構除了在安全的資訊傳輸時間上比SSL-VPN資訊傳輸架構快56 % 、支援更多的行動裝置(如PDA)、資訊應用系統以及訊號中斷之影響低等優點外，與既有企業資訊環境整合性高、行動裝置硬體規格需求低、連線頻寬需求低等特性更能滿足行動工作者的使用需求，使企業M化後更具市場競爭力。

The 21st century enterprises competitive ability important target is Enterprise Mobilization that as a result of the wireless technical progress and the running gear application popularization. How but establishes up to the safe fast information transmission overhead construction is the Enterprise Mobilization success or not most important factor.

At present Enterprise Mobilization generally take SSL-VPN as in the enterprise information transmission overhead construction application environment, although may provide the enterprise the motion worker in the enterprise outside security deposit and withdrawal enterprise information, but, after because SSL-VPN does not support the PDA running gear, does not support records is the authentication type the non-Web information system operation pattern (this kind of system occupies enterprise information system approximately 70%), the accidental signal severance the original information system is unable to continue to operate and so on the shortcoming as well as the running gear segment frequency width demand must high, CPU of running gear carry out the speed to have quick, the storage memory essential to be big and so on the motion environmental factor, creates enterprise information which the motion worker is unable to obtain immediately, Then influence enterprise competitive ability.

Therefore, this research proposed information of transmission overhead construction by terminal service young, the affiliation by the terminal technology (Terminal Technology) the central operation handling ability, the terminal device hardware demand low, the information transmission quantity is small, is affected slightly the signal severance and so on the characteristic solves the SSL-VPN transmission overhead construction shortcoming, simultaneously by way of really makes the confirmation to propose accuracy of the overhead construction.

This research demonstration take the terminal service as the information transmission overhead construction except in the safe information transmission time compared to the SSL-VPN information transmission overhead construction quick 56 %, supports the more running gear (for example PDA), the information application system as well as the signal severance affects and so on outside lowly the merit, with already has the enterprise information environment conformity rate high, the running gear hardware specification demand low, the line frequency width demand is continually low and so on the characteristic can meet the motion worker's use need, after causes enterprise M to have the market competition strength.
