Description
本發明關於一種交易風控裝置，尤其關於一種包含一快速查找裝置的交易風控裝置。The present invention relates to a transaction risk control device, and more particularly to a transaction risk control device comprising a quick search device.
在金融交易領域上，金融商品的交易金額瞬息萬變，當交易資訊或金融商品資訊傳輸延遲時，易造成用戶偌大的損失，因此如何在分秒必爭的金融交易領域上快速傳遞客戶的交易資訊成了重要的課題。In the field of financial transactions, the transaction amounts of financial products change rapidly. When the transmission of transaction information or financial product information is delayed, it is easy to cause huge losses to users. Therefore, how to quickly transmit customers' transaction information in the financial transaction field where every second counts has become an important issue.
然而，當前在期貨交易領域上，用戶透過期貨經紀商向期貨交易所提出交易請求時，由於用戶與期貨經紀商之間使用的通訊協定不同於期貨經紀商與期貨交易所之間使用的通訊協定，導致用戶提出的交易請求必須先以期貨經紀商作為目標位置，透過期貨經紀商轉址並修改交易請求的編寫方式，令期貨交易所得以接收並讀取交易請求。唯，習用方式相當依賴期貨經紀商的設備，一旦期貨經紀商的設備運算能力不足時，易造成交易請求延遲。However, in the current futures trading field, when users submit trading requests to futures exchanges through futures brokers, the communication protocol used between users and futures brokers is different from the communication protocol used between futures brokers and futures exchanges. As a result, the trading requests submitted by users must first use futures brokers as the target location, and the futures brokers redirect and modify the writing method of the trading requests so that the futures exchanges can receive and read the trading requests. However, the usual method is highly dependent on the equipment of futures brokers. Once the computing power of the equipment of futures brokers is insufficient, it is easy to cause delays in trading requests.

圖1顯示本發明一實施例之交易系統的結構的示意圖。如圖1所示，交易系統100包括有一作業中心主機151、一交易風控裝置120及一使用者裝置153。交易風控裝置120連接一作業中心主機151及一使用者裝置153，例如可透過網路111連接作業中心主機151及交易風控裝置120，並透過線路112連接交易風控裝置120及使用者裝置153。交易風控裝置120可以連接於使用者裝置153的一網路傳輸裝置。使用者裝置153及作業中心主機151通過交易風控裝置120傳輸資料封包，以便進行交易。在實際應用時，使用者可透過使用者裝置153經由交易風控裝置120向作業中心主機151發出交易訊息。FIG1 is a schematic diagram showing the structure of a trading system of an embodiment of the present invention. As shown in FIG1 , the trading system 100 includes an operation center host 151, a trading risk control device 120 and a user device 153. The trading risk control device 120 is connected to an operation center host 151 and a user device 153, for example, the operation center host 151 and the trading risk control device 120 can be connected via a network 111, and the trading risk control device 120 and the user device 153 can be connected via a line 112. The trading risk control device 120 can be connected to a network transmission device of the user device 153. The user device 153 and the operation center host 151 transmit data packets through the trading risk control device 120 to conduct transactions. In actual application, the user can send a transaction message to the operation center host 151 through the user device 153 via the transaction risk control device 120.
交易風控裝置120可減少交易延遲狀況且可提供風險控管。交易風控裝置120可以接收一封包113後，快速地解串（deserialize）封包113，找出封包113中的標籤及對應該標籤的產品資訊，並且快速地對封包113進行風險控管處理，而可解決習用交易方式因風險控管導致交易延遲的情況。一實施例中，封包113可以為一交易封包或一回覆封包。The transaction risk control device 120 can reduce transaction delays and provide risk control. After receiving a packet 113, the transaction risk control device 120 can quickly deserialize the packet 113, find the tag in the packet 113 and the product information corresponding to the tag, and quickly perform risk control processing on the packet 113, thereby solving the problem of transaction delays caused by risk control in the conventional transaction method. In one embodiment, the packet 113 can be a transaction packet or a reply packet.
圖2顯示本發明一實施例之交易風控裝置的示意圖。圖3顯示本發明一實施例之交易風控裝置中映射表裝置與SRAM池連接時的示意圖。如圖2所示，交易風控裝置120包含一快速查找裝置210、一標籤M-2解串器221、一標籤M-1解串器231及一風險評估引擎222。一實施例中，標籤M-2解串器221及標籤M-1解串器231分別用以對封包113進行解串，取得封包113中的標籤以及對應該標籤的封包資訊。風險評估引擎222利用該標籤以及該封包資訊取得一產品資訊（info of product），再根據該產品資訊及儲存於其中的風險控管條件，對封包113所包含的交易訊息進行風險控管處理。FIG2 is a schematic diagram of a transaction risk control device according to an embodiment of the present invention. FIG3 is a schematic diagram of a mapping table device in a transaction risk control device according to an embodiment of the present invention when connected to an SRAM pool. As shown in FIG2 , the transaction risk control device 120 includes a quick search device 210, a tag M-2 deserializer 221, a tag M-1 deserializer 231, and a risk assessment engine 222. In one embodiment, the tag M-2 deserializer 221 and the tag M-1 deserializer 231 are respectively used to deserialize the packet 113 to obtain the tag in the packet 113 and the packet information corresponding to the tag. The risk assessment engine 222 uses the tag and the packet information to obtain product information, and then performs risk control processing on the transaction information included in the packet 113 according to the product information and the risk control conditions stored therein.
為了加快對交易訊息的處理，一實施例中，交易風控裝置120使快速查找裝置210接收封包113，並且利用快速查找裝置210取得封包113中的標籤以及封包資訊，再利用該標籤以及該封包資訊，藉以較快速地取得一產品資訊。風險評估引擎222接收該產品資訊，再根據該產品資訊及儲存於其中的風險控管條件，對封包113所包含的交易訊息進行風險控管處理。以下，將更詳細地說明快速查找裝置210的操作。In order to speed up the processing of transaction information, in one embodiment, the transaction risk control device 120 enables the quick search device 210 to receive the packet 113, and uses the quick search device 210 to obtain the label and packet information in the packet 113, and then uses the label and the packet information to obtain a product information more quickly. The risk assessment engine 222 receives the product information, and then performs risk control processing on the transaction information contained in the packet 113 according to the product information and the risk control conditions stored therein. The operation of the quick search device 210 will be described in more detail below.
如圖2及3所示，快速查找裝置210包含一標籤N解串器211、一映射表裝置212及一靜態隨機存取記憶體池（Static Random Access Memory Pool，SRAM池）213。標籤N解串器211對封包113進行解串，用以取得封包113中的標籤以及對應該標籤的封包資訊。一實施例中，封包113中的標籤或封包資訊可以為一產品識別碼（產品ID），並且封包113被標籤N解串器211進行解串後以使該產品ID被輸出。如圖3所示，映射表裝置212接收該產品ID後，輸出一地址addr，該地址addr為SRAM池213中的儲存有對應於該產品ID之產品資訊的一記憶位址addr。風險評估引擎222依據該記憶位址addr從SRAM池213取得產品資訊（Info of Product）。再根據該產品資訊及儲存於其中的風險控管條件，對封包113所包含的交易訊息進行風險控管處理。As shown in FIGS. 2 and 3 , the quick search device 210 includes a tag N deserializer 211, a mapping table device 212, and a static random access memory pool (SRAM pool) 213. The tag N deserializer 211 deserializes the packet 113 to obtain the tag in the packet 113 and the packet information corresponding to the tag. In one embodiment, the tag or packet information in the packet 113 may be a product identification code (product ID), and the packet 113 is deserialized by the tag N deserializer 211 so that the product ID is output. As shown in FIG. 3 , after receiving the product ID, the mapping table device 212 outputs an address addr, which is a memory address addr in the SRAM pool 213 storing the product information corresponding to the product ID. The risk assessment engine 222 obtains product information (Info of Product) from the SRAM pool 213 according to the memory address addr, and then performs risk control processing on the transaction information included in the packet 113 according to the product information and the risk control conditions stored therein.
較佳的情況是，映射表裝置212是一種邏輯裝置，並且利用邏輯電路儲存有一映射表，映射表是一種產品ID到SRAM池213之記憶位址addr的對應表格。一實施例中，映射表裝置212包含一比較電路群組241，比較電路群組241包含數萬多組並行處理的比較電路，且該映射表儲存於比較電路群組241中。較佳地，在該些數萬筆的比較電路中，已預先設定有多數的預定比較值，一實施例中，為了電路設計的簡便以及減少電路的大小，將大多數的比較值設定為固定值，亦即不可變更地寫入於該些電路中。因此，儲存於比較電路群組241中的該映射表為不可被修改的資料。更具體而言，比較電路群組241的具有該些比較值的該些比較電路，構成為能夠讓映射表裝置212接收該產品ID後輸出該地址addr，而且由於本領域具有通常知識者能夠依據前述說明，設計出比較電路群組241的電路，因此省略了該電路的具體設計的說明。此外，比較電路群組241可以使用目前現有或未來發展的技術。在本實施例中，為了能夠進行快速的查找功能，採用了邏輯電路來進行快速的查找，因此能夠更進一步快速地使風險評估引擎222從SRAM池213接收該產品資訊，再根據該產品資訊及儲存於其中的風險控管條件，對封包113所包含的交易訊息進行風險控管處理。Preferably, the mapping table device 212 is a logic device, and uses a logic circuit to store a mapping table, which is a correspondence table from a product ID to a memory address addr of the SRAM pool 213. In one embodiment, the mapping table device 212 includes a comparison circuit group 241, the comparison circuit group 241 includes tens of thousands of comparison circuits processed in parallel, and the mapping table is stored in the comparison circuit group 241. Preferably, a plurality of predetermined comparison values are pre-set in the tens of thousands of comparison circuits. In one embodiment, in order to simplify the circuit design and reduce the size of the circuit, most of the comparison values are set to fixed values, that is, they are written into the circuits in an unchangeable manner. Therefore, the mapping table stored in the comparison circuit group 241 is data that cannot be modified. More specifically, the comparison circuits with the comparison values of the comparison circuit group 241 are configured to enable the mapping table device 212 to output the address addr after receiving the product ID, and since a person skilled in the art can design the circuit of the comparison circuit group 241 according to the above description, the specific design description of the circuit is omitted. In addition, the comparison circuit group 241 can use currently existing or future developed technologies. In this embodiment, in order to perform a fast search function, a logic circuit is used to perform a fast search, so that the risk assessment engine 222 can further quickly receive the product information from the SRAM pool 213, and then perform risk control processing on the transaction information contained in the packet 113 based on the product information and the risk control conditions stored therein.
依據習知技術，皆是使用者裝置153利用軟體來完成封包113的解串，以及產品資訊的查找。然而，這樣的方法，需要通過微處理器或是電腦的中央處理器（CPU）來進行運算，再從儲存於硬碟中資料庫取得該產品資訊，如此增加了交易延遲狀況。相對於此，依據本發明一實施例，設置有快速查找裝置210，其能夠直接對一封包113進行解串，取得封包113中的標籤以及封包資訊，並且根據標籤或封包資訊，從採用一邏輯電路儲存一映射表的映射表裝置212，快速地取得一記憶位址addr，再依據SRAM池213的該記憶位址addr輸出對應該封包的產品資訊（Info of Product）。因此，相對於習知技術，能夠加快交易處理，而減少交易延遲狀況。According to the prior art, the user device 153 uses software to deserialize the packet 113 and search for product information. However, this method requires a microprocessor or a central processing unit (CPU) of a computer to perform calculations and then obtain the product information from a database stored in a hard disk, which increases transaction delays. In contrast, according to an embodiment of the present invention, a fast search device 210 is provided, which can directly deserialize a packet 113, obtain the tag and packet information in the packet 113, and quickly obtain a memory address addr from a mapping table device 212 that uses a logic circuit to store a mapping table according to the tag or packet information, and then output the product information (Info of Product) corresponding to the packet according to the memory address addr of the SRAM pool 213. Therefore, compared with the prior art, the transaction processing can be accelerated and the transaction delay can be reduced.
在股票市場中上市公司會因各種原因新增或退出，然而，在映射表裝置212只包含比較電路群組241的實施例中，無法變更映射表的資料，缺乏了適應性。一實施例中，較佳地，映射表裝置212可以更包含一可配置暫存器（Register）242，用以儲存新增的、被修改的或未來可變化的資料。亦即，可以將未來變化的資訊，儲存於可配置暫存器（Register）242中。In the stock market, listed companies may be added or withdrawn for various reasons. However, in the embodiment where the mapping table device 212 only includes the comparison circuit group 241, the data in the mapping table cannot be changed, which lacks adaptability. In one embodiment, preferably, the mapping table device 212 may further include a configurable register (Register) 242 to store the added, modified or future changeable data. That is, the information of future changes may be stored in the configurable register (Register) 242.
依據本發明一實施例，由於快速查找裝置210包含利用邏輯電路儲存映射表的映射表裝置212，能夠充份利用邏輯電路快速運作的效果，較快速地輸出一記憶位址addr，而可以更快速地從SRAM池213取得產品資訊（Info of Product），進而能夠加速交易處理，而減少交易延遲狀況。According to an embodiment of the present invention, since the fast search device 210 includes a mapping table device 212 that uses a logic circuit to store a mapping table, it can fully utilize the effect of the fast operation of the logic circuit to output a memory address addr more quickly, and can obtain product information (Info of Product) from the SRAM pool 213 more quickly, thereby accelerating transaction processing and reducing transaction delays.
