    無線覆蓋教育行業解決方案

    行業需求

           在教育信息化快速發展的今天,校園網已經成為校園生活的重要組成部分,無線網絡一方面實現了電子書包、無線校園等電子應用的普及,另一方面也是教職工和學生獲取資源和信息的重要途徑。校園無線網絡建設將校園里的教職工、師生更加緊密的聯系在一起,在教育系統中發揮更為重要的作用。

    校園網絡的技術需求

           作為各類校園應用的底層支持平臺,校園網絡的容量、性能、穩定性和安全性對校園應用的實現和穩定運行起著至關重要的作用。

    從校園各項應用的特點來看,校園網的技術要求主要集中在以下幾個方面:

           無線終端數量增加迅速,種類繁多,要求校園網具有良好的無線終端兼容性和高密度終端接入能力,能夠提供穩定、高性能的無線網絡連接;

           校園網用戶數量增加迅速,身份各異,要求校園網具有基于身份角色的動態策略控制機制,能夠依據用戶身份靈活控制每個用戶的訪問權限、帶寬策略、連接數策略、路由策略、甚至不同的認證歡迎頁面 ;

           校園無線應用數量增加迅速,種類繁多,要求無線校園網具有優異的應用識別能力和基于應用的QoS保證能力,尤其對于無線多媒體業務,還需要支持自動優化機制 ;

           校園網需要具有開放的應用接口,能夠與外部系統互通和聯動,借助無線網絡與生俱來的定位能力,提供完備的終端位置信息的實時查詢和導出機制,實現校園定位功能;

          “無所不在”的智慧校園要求校園網具有平滑擴展能力,能夠實現室內、室外的全校無縫覆蓋,并且可以將校園網有線和無線接入能力安全地延伸到遠程教學點、甚至學校教職工的家中;

     

     

    校園網絡構成

           移動控制器: 部署在各校區中心機房,主要負責對全網所有無線和有線接入點進行集中管控,并提供全網有線用戶和無線用戶的集中認證和策略控制功能;

           無線接入點: 部署在各個需要無線覆蓋的區域,提供無線用戶的認證和接入服務,同時對射頻環境中可能出現的各種無線攻擊行為及無線安全漏洞進行實時掃描,并自動壓制,以保護有線網絡免受來自無線技術的攻擊和入侵威脅;

           有線接入點: 部署在會議室和教室等公共區域,提供有線用戶身份認證和基于角色的訪問控制器服務,以實現安全、可移動的有線接入網絡; 

           無線網管系統: 部署在網絡中心機房,負責對全網所有接入設備(包括移動控制器、無線和有線接入點)進行統一的配置管理、故障管理和性能管理,收集并維護整個網絡運行狀態、使用效率的實時和歷史數據,并形成報表,為校園網的進一步優化配置提供依據; 

           訪客管理系統: 部署在網絡中心機房,主要負責在全校范圍內提供訪客接入帳號的自助注冊、自助服務和短信發送等管理功能,同時支持在訪客注冊和登錄頁面上以問卷調查的方式收集用戶信息,并可以基于用戶信息向用戶頁面或者手機自動發送智能廣告信息;

    應用效果

            通過校園網絡建設,采用先進的網絡設備、網絡方案使學校具備了高性能、多服務、高可靠、高安全、易管理的校園教育綜合網絡,建成了高效運轉的校園網絡平臺,極大地促進了教育信息化建設,極大方便了學校網絡教學、管理、有效提升了網絡服務質量,為師生提供了高速信息網絡服務。
