          商城型的網站的內部結構應該怎么布置才合理

          大眾型網絡平臺一般的有哪些結構

           

            一般來講,電子商務網絡平臺的一般結構。一個良好的電子商務網絡平臺應當滿足以下要求:支持網絡的互聯和應用的互操作;能夠隔離和控制不同用戶對系統的訪問,保證網絡設備的安全;網絡環境是可以管理的。電子商務系統的網絡平臺的每個部分都有不同的要求。

            (一)Internet部分。Internet部分是企業電子商務系統的用戶訪間接口,是企業與客戶之間相互交流的通道。建設電子商務系統Internet部分的目的主要是實現企業Intranet和Internet之間的互聯,它的主要內容包括兩部分接口方式、接口規格的設計以及相互連接。電子商務系統與Internet的互聯方式很多。目前常見的方式是通過公共電話網、數字數據網DDN(例如ChinaDDN )、分組交換網PSDN如ChinaPAC)等方式將企業電子商務系統接人Internet。詳見后面介紹的接人方式。

            (二)電子商務系統的局域網部分。電子商務系統Web服務器、應用服務器等一般運行于局城網上,該局域網一般需要滿足以下要求:

            (1)由于用戶通過Internet訪問服務器時,要求比較高的響應速度,因此,需要在局域網上配皿高性能的服務器,而且要求網絡具備較高的帶寬,并且該局域網一般利用LAN Switch構造。

            (2)電子商務系統的局域網必須具備隔離措施,提供可靠的和安全的網絡環境。電子商務系統的局域網不僅和Internet互聯,而且墓本上還需要和企業的內部網絡連接,在這種情況下,LAN上的主機設備、應用系統和企業內部信息系統在理論上都存在被非法用戶人侵的可能。如采商務應用系統遭到惡念攻擊,那么企業的商務活動就可能受到影響,所以強化網絡的安全是非常必要的,一般可以采取設皿防火墻,將網絡隔離成敏感程度不同的區域;或者將網絡劃分為信任等級不同的網段,通過路由設備隔離等措施。

          大眾型網絡平臺一般的有哪些結構

            (三)Intranet和Extranet。從電子商務系統的體系結構來看,Intranet建設所包含的主要任務是完成內部信息系統和電子商務系統的互聯問題,而Extranet建設所要完成的任務則主要是電子商務系統如何和外部信息系統(例如銀行、CA等)的互聯問題。電一子商務網絡平臺從硬件角度考慮,網絡的簡略構成是網絡服務器、應用終端(或工作站)以及用于聯系網絡服務器和終端的交換機、路由器、集線器等設備和其他保障網站營銷功能的設備。
