通過對基于流概念的實時流測量系統(tǒng)RFC 2722 RTFM的形式化描述，討論了實時流測量系統(tǒng)中各元素之間的關(guān)系。在實時流測量系統(tǒng)的基礎(chǔ)上，通過測量目標定義了系統(tǒng)中各元素間的協(xié)作關(guān)系，引入了資源策略服務(wù)器組件，建立了維護系統(tǒng)資源一致性的機制和適合目前因特網(wǎng)流量統(tǒng)計的分布式實時流監(jiān)測體系結(jié)構(gòu)，并討論了其原型系統(tǒng)的實現(xiàn)。

Realtime Traffic Flow Measurement (RTFM) system architecture RFC2722 is described based on the concept of flow. The relations among elements RTFM system are also discussed. Based on RTFM, resource policy service component maintaining the consistency of system resource is introduced. The cooperating relations between each element are defined on the measurement object. Consequently, a distributed traffic flow measurement system architecture that adapt to Internet traffic management is given and the implementation of prototype system is discussed.
