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Flow control method and system for reducing server operating pressure and improving response time

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.

As shown in the figure, the flow control system 111 for reducing the operating pressure of the server and improving the response time is set in a communication intermediary program 11 of a client 1 in the futures and securities industry, for controlling at least one client 1 and at least one Data transfer rate between server 2. The client 1 is provided with a user application 10 , which is telecommunicationly connected to the communication intermediary program 11 , and the communication intermediary program 11 is further provided with a data buffer module 110 , a data reception module 112 and a data output module 113 . The flow control system 111 is provided with a rate counting module 1110, a rate adjusting module 1111 and an abnormal counting module 1112. The data receiving module 112 is telecommunicationly connected to the server 2 and the rate counting module 1110. The rate The counting module 1110 is telecommunicationly connected to the rate adjustment module 1111 and the abnormal counting module 1112, the rate adjustment module 1111 is telecommunicationly connected to the data output module 113 and the abnormal counting module 1112, and the flow control system 111 operates The method can include the following steps:

步驟S20，該使用者應用程式10傳送至少一使用者請求資料1100至該資料緩衝模組110。步驟S21，該資料輸出模組113自該資料緩衝模組110讀取該使用者請求資料1100後，步驟S210，傳送予該伺服端2，以供該伺服端2進行處理。待該伺服端2處理完成而反饋一處理結果予該資料接收模組112時，步驟S22，該速率計數模組1110讀取該伺服端2處理資料之回應時間，且於步驟S23中即時計算該回應時間而獲知該伺服端2之回應速率。同時，步驟S230，該資料接收模組112傳送該處理結果予該使用者應用程式10。In step S20 , the user application 10 transmits at least one user request data 1100 to the data buffer module 110 . In step S21 , after the data output module 113 reads the user request data 1100 from the data buffer module 110 , in step S210 , the data is sent to the server 2 for processing by the server 2 . When the processing of the server 2 is completed and a processing result is fed back to the data receiving module 112, in step S22, the rate counting module 1110 reads the response time of the data processed by the server 2, and immediately calculates the response time in step S23. The response rate of the server 2 is obtained by the response time. Meanwhile, in step S230 , the data receiving module 112 transmits the processing result to the user application 10 .

步驟S24，該速率調節模組1111判斷該回應速率是否符合一預設值，例如每筆傳送予該伺服端2之資料封包之處理回應時間是否為10～20ms？若不符合，步驟S240，輸出一調節訊號予該資料輸出模組113，使該資料輸出模組113於步驟S25中調節自該資料緩衝模組110讀取該使用者請求資料1100之速率，以調節傳送該使用者請求資料1100至該伺服端2之速率，藉此降低該伺服端2之運作壓力而提升該回應速率。換言之，該流量控制系統111係依據前一筆傳送之資料封包之回應時間作為調節讀取該資料緩衝模組110之速率之基準，故當前一筆資料封包之回應速率不符該預設值時減低該資料輸出模組113讀取該資料緩衝模組110之速率，而於前一筆資料封包之回應速率符合該預設值時即以原始讀取速率或以調高一階級速率之讀取速率讀取該資料緩衝模組110，換言之， 該資料輸出模組113係以浮動速率傳送該使用者請求資料1100至該伺服端2，使可切實解決該使用者請求資料1100列隊儲存於該伺服端2之緩衝區內而造成該伺服端2之運算資源耗費及影響整體工作效率的問題。In step S24, the rate adjustment module 1111 determines whether the response rate conforms to a preset value, such as whether the processing response time of each data packet sent to the server 2 is 10-20ms? If not, in step S240, an adjustment signal is output to the data output module 113, so that the data output module 113 adjusts the speed of reading the user request data 1100 from the data buffer module 110 in step S25, so as to The rate of transmitting the user request data 1100 to the server 2 is adjusted, thereby reducing the operating pressure of the server 2 and increasing the response rate. In other words, the flow control system 111 is based on the response time of the data packet sent in the previous transmission as the benchmark for adjusting the rate of reading the data buffer module 110, so when the response rate of the current data packet does not meet the preset value, the data is reduced. The output module 113 reads the speed of the data buffer module 110, and when the response rate of the previous data packet meets the preset value, reads the data at the original read rate or at the read rate increased by one level. The data buffer module 110, in other words, the data output module 113 transmits the user request data 1100 to the server 2 at a floating rate, so that the buffering of the user request data 1100 queued and stored in the server 2 can be effectively solved In this area, the computing resource consumption of the server 2 and the problem of affecting the overall work efficiency are caused.

並且，步驟S26，該異常計數模組1112即時計算該回應時間而獲知一異常訊號後，解析該異常訊號並獲知一異常頻率，以使該速率調節模組1111依據該異常頻率調節該資料輸出模組113自該資料緩衝模組110讀取資料之速率。如此，即使該伺服端2受其系統運作特性影響而間斷地出現有瞬間工作速率下降的狀況，該速率調節模組1111仍可即時調控讀取速率並影響傳輸速率而確保該伺服端2運作品質，使有效避免期貨證券商之委託資料出現錯誤處理而產生金融糾紛等問題的發生，達利益產業經濟發展之效益。And, in step S26, after the abnormality counting module 1112 calculates the response time in real time and obtains an abnormal signal, it analyzes the abnormal signal and obtains an abnormal frequency, so that the rate adjustment module 1111 adjusts the data output mode according to the abnormal frequency. The rate at which the group 113 reads data from the data buffer module 110 . In this way, even if the server 2 is affected by its system operation characteristics and the instantaneous working rate drops intermittently, the rate adjustment module 1111 can still adjust the read rate in real time and affect the transmission rate to ensure the operation quality of the server 2 , so as to effectively avoid the occurrence of financial disputes and other problems caused by the wrong processing of the entrusted data of the futures securities firm, and achieve the benefits of the economic development of the beneficial industry.

於本實施例中，該流量控制系統11適用於單一用戶端1對單一伺服端2、多用戶端1對單一伺服端2及多用戶端1對多伺服端2之通訊架構中，而當該用戶端1為複數使用型態時，各該資料輸出模組113可分別設有一權重值，且該伺服端2依據該權重值接收各該用戶端1不同數量之該使用者請求資料1100，如此，該伺服端2單次將對具較高權重值之該用戶端1接收及處理較多資料量。另一方面，當該伺服端2為複數使用型態時，該速率調節模組1111可比對並排序各該伺服端2之回應速率，以依據該等回應速率之先後排序使該資料輸出模組113傳送該使用者請求資料1100，如此，該用戶端1將優先請求具較高回應速率之該伺服端2處理資料。In this embodiment, the flow control system 11 is applicable to the communication structure of single client 1 to single server 2, multiple clients 1 to single server 2, and multiple clients 1 to multiple servers 2, and when the When the client 1 is in the plural usage type, each of the data output modules 113 may be respectively set with a weight value, and the server 2 receives the user request data 1100 of different quantities of the client 1 according to the weight value, and so on , the server 2 will receive and process a larger amount of data from the client 1 with a higher weight value at a time. On the other hand, when the server 2 is in a plural use type, the rate adjustment module 1111 can compare and sort the response rates of the servers 2, so as to make the data output module according to the order of the response rates. 113 sends the user request data 1100, so that the client 1 will preferentially request the server 2 with a higher response rate to process the data.
