在網際網路之蓬勃發展下,網際網路通訊協定技術已是網路運用的最新趨向;電信網路與資訊網路將逐漸融合形成為IP Based的網路。新一代的國軍資通系統骨幹網路,已朝向電信網路與資訊網路全數整合於非同步傳輸模式技術為核心的網路平台上,並以多重協定標籤交換技術執行IP Based的網路運用,同時在硬體設備及通信協定上也全數具備了服務品質(Quality of Service , QoS)管控能力。探討國軍資通系統所具備ATM、IP、MPLS架構與QoS技術,分析國軍電路需求特性,發現運用虛擬私有網路及服務品質的能力,建立適切的QoS規劃與管理作為,為有限的通資資源下,解決國軍資通系統網路頻寬管理問題及提高電路存活率的有效方法之一。
目前國軍資通系統的網路管理,針對電路特性、建立優先秩序的經驗及機制仍有精進空間。如何建立國軍資通系統的網路QoS管理作為,彈性控管頻寬、保障電路品質、增加網路效能及資訊確保能力,將是網路管理的重要議題。
本研究探討分析國軍資通系統網路架構及所具的QoS功能,並依各單位用戶電路需求特性,共獲得:QoS的運用、管理機制及配套措施等計八項建議:1.軍種邊緣設備統一由網路提供單位直接管制設定,以改善處理效能。2.定期評估網路效能、製作分析報表,以提供管理設備資訊及策略調整。3.發揮服務水準協議的精神,精確的調整封包遺失率,及預測頻寬的使用量。4.量身訂做服務等級,確保網路最大效能。5.各軍種網路管理者注意QoS的功能與限制,以達成全程管控的目標。6.依國際相關標準及用戶的電路需求特性設定QoS的參數,有效支援重要演訓等突發及大量頻寬需求。7.明確律定QoS相關政策的單位,並詳訂維管及網路流量管控權責,以達終端至終端全面管理的目標。8.增加QoS管理子系統,以具備集中頻寬控管能力,有效支援整體網路QoS管理。上述建議冀望能提供權責單位正視網路服務品質管理機制的發展與運作,以提昇國軍資通基礎建設的能量。
With the vigorous development of Internet, Internet protocol (IP) technique is the newest trend for network applications. Tele-communication and data-communication will be gradually combined to an IP based network. The new Military Information Communication Systems (MICS) has integrated the tele-communication and data-communication on a platform with asynchronous transfer mode (ATM) as the core technique, and utilized the multiprotocol label switching (MPLS) to conduct IP based network applications. Meanwhile, the Quality of Service (QoS) control is euipped on both hardware and communication protocols. Under limited communication and information resources, we discuss ATM, IP, MPLS structures and QoS technique, analysis the requirement of the MICS features, discover the capability to utilize VPN and QoS, to establish suitable QoS planning and management workflow, in order to solve the bandwidth management issues of the MICS and to improve circuit survivability.
For the circuit features of MICS management, the experiences and mechanisms of priority set ups still need to be improved. How to set up QoS control methods for MICS, manage bandwidth flexibly, ensure circuit quality, enhance network efficiency and ensure information communication capabilities will be critical issues of network management.
By studying network structure and its QoS ability, eight suggestions such as QoS applications, control mechanisms and response measures etc. are acquired according to user’s circuit requirements. 1. Network service providing unit controls and sets the service side equipments in order to improve the processing efficiency. 2. Evaluating the network efficiency and produce analysis report regularly for providing equipment management information and strategic adjustments. 3. Adjust packet loss rate precisely and predict the bandwidth usage in order to achieve the function of QoS protocol. 4. Fitting the QoS as required to ensure the maximum network efficiency. 5.3 Network supervisors from each service may notice the function and limitation of the QoS to achieve the full-spectrum control. 6. Set up the QoS parameters according to international standards and the requirement of the end users in order to support planned or non-planned large bandwidth requirement such as major exercises. 7. Specify the unit in charge of QoS, and assign the rules for management and network bandwidth control to achieve the full-spectrum management from terminal to terminal. 8. Create QoS management subsystem for unify bandwidth control capability and effectively support the QoS management for the whole system. Hope the unit in charge may focus on the development and operation of QoS mechanisms in order to increase the capabilities of communication and information infrastructures for the armed forces.
