Description
本發明係與網路資料流量控制方法及其系統有關,尤其是一種降低伺服端運作壓力並提升回應時間之流量控制方法及其系統。The present invention relates to a network data flow control method and system, in particular to a flow control method and system for reducing operating pressure on a server and improving response time.
為降低產業軟體的開發成本,廣泛應用於能源、電信、金融、銀行、醫療或教育等產業之商業資訊程序係多利用通訊中介程序(Communication Middleware)之技術構建而出。通訊中介程序是一類提供系統軟體和應用軟體之間連接及協助軟體各部件間溝通的程序,供置於用戶端之伺服器上而管理用戶伺服系統之計算資源及網路通信狀態,因此,用戶端之伺服器及伺服端之伺服器雙方並不會知道彼此的資料處理速率及工作壓力指數。一般,在多數時間裡,伺服端必須處理由用戶端一次傳送來的複數個使用者請求資料而作業忙碌,且為解決伺服端無法即時處理該等使用者請求資料而造成資料遺失或錯誤處理的問題,習知係利用擴增伺服端之伺服器內緩衝區容量的技術使用戶端持續傳送來之該等使用者請求資料佇列其中,以緩解作業程序。In order to reduce the development cost of industrial software, business information programs widely used in industries such as energy, telecommunications, finance, banking, medical care or education are constructed using the technology of Communication Middleware. A communication intermediary program is a program that provides connection between system software and application software and assists in the communication between various components of the software. The server on the side and the server on the server side do not know each other's data processing rate and work pressure index. Generally, in most of the time, the server must process multiple user request data sent by the client at one time, and the operation is busy, and in order to solve the problem that the server cannot process the user request data immediately, resulting in data loss or error processing The problem is that the conventional technology utilizes the technology of expanding the buffer capacity in the server side to make the user request data continuously transmitted from the client side queue in it, so as to ease the operation procedure.
只是,未能即時處理之該等使用者請求資料佇列等待於緩衝區係造成伺服資源被佔用及耗費的問題發生,使伺服端呈現工作壓力大而拉長了其資料處理的反應時間,仍不利於整體網路資料處理效率的完善。再者,若伺服端於其高工作壓力期間接收該等使用者請求資料時會反饋一拒收訊號予用戶端並拒絕接收資料,則將出現有用戶端持續不斷地重覆傳送請求而伺服端亦持續不斷地反饋拒收訊號的狀況而更加浪費伺服端資源,並嚴重影響整體工作效率而無法符合期貨證券產業對於資料處理高精確性及高速效性的要求。However, these user requests that cannot be processed in real time are queued and waited in the buffer, which causes the problem of server resources being occupied and consumed. It is not conducive to the improvement of the overall network data processing efficiency. Furthermore, if the server will feed back a rejection signal to the client and refuse to receive the data when it receives the data requested by the user during the period of high working pressure, there will be a client that continuously repeats the transmission request and the server It also continuously feeds back the status of the rejection signal, which further wastes server resources and seriously affects the overall work efficiency.
