The efficiency of ETC split business is increased by 90%, the efficiency of ETC clearing and accounting is increased by 60%, and the report generation time is shortened by about 90%. A single node can complete 175,000 data storage per second...

This is the operation data of AsiaInfo Technology’s AntDB database in the Yunnan high-speed core business system in the past two years.

AsiaInfo “carrier-grade” core transaction database AntDB Efficiently meet business needs

In 2019, relevant ministries and commissions of China proposed to “cancel expressway provincial boundary toll stations within two years” to achieve fast toll collection without stopping, reduce congestion and facilitate the people. This requires the provincial highway billing system to be networked and data shared with the center of the Ministry of Transport. To this end, the Yunnan Provincial Expressway Operation and Management Center has started an all-round upgrade of the clearing and settlement system.

The database stores the data of thousands of vehicles on high-speed passage and the operation and management of road administration units, and the settlement of various highway fees, refund and payment, expansion transactions and even dispute handling all depend on the information support of the database. “Highway Clearing and Settlement System” is responsible for storing and processing all kinds of transaction flows issued by the toll collection system, accounting information issued by the departmental center, etc., and generating clearing and settlement data, which is a typical HTAP (online transaction and online analysis) scenario and has extremely high requirements for the OLTP (online transaction processing) and OLAP (online analysis and processing) capabilities of the database. At the same time, import and export of massive data, access and process association of huge and complex system, data migration and business support in a short time... All these present challenges for database product and service teams. Yunnan Highway Network Toll Management Co., Ltd. chose AntDB, a carrier-class and distributed core transaction database independently developed by AsiaInfo Technology, to upgrade and replace the original database to achieve comprehensive independent and controllable core business systems.

With its high availability, high reliability, and high stability product performance, AntDB supports the ultra-high concurrency and efficient operation of the Yunnan high-speed clearing and settlement system, so that the provincial center has a unified data service capability and the “whole process + multi-protocol + high performance + full business data” processing capability of massive data, which ensures that the processing efficiency of customer clearing and settlement business is greatly improved, and provides strong support for the departmental and provincial business coordination after the cancellation of the provincial boundary highway toll station. It has also set a model for the use of domestic independent and controllable products in various industries.

Zhang Chenglin, deputy general manager of Yunnan Highway Network Toll Management Co., Ltd., said that the system has run smoothly since it was launched, realizing the unified processing of multi-source, multi-dimensional, and multi-type data, and the efficient clearing and settlement system has also made it more convenient for people to travel at high speed.

Committed to independent innovation, safe, and controllable technology Help customers create a precedent in China

As a domestic database with independent innovation, AsiaInfo AntDB adopts a native distributed architecture, which is transparent to applications and supports centralized, distributed, and cloud-based deployment modes. It provides petabyte-level data processing capabilities, with high performance, high reliability, elastic expansion, and other characteristics, and has no limit on CPU, memory, and connections. Built-in distributed parallel execution engine supports multi-node concurrent data processing, and the increase in the number of nodes can make the product performance increase linearly. Users can obtain better performance and optimal cost of ownership according to their own needs; AntDB supports remote disaster recovery, reaches a disaster preparedness level of 99.999%; Supports read/write splitting to ensure a better performance experience for customers.

At present, AntDB has completed compatibility tests with domestic chips such as Feiteng, Kunpeng, Haiguang, Loongson, and domestic operating systems such as UnionTrust, Kylin, and Euler. AntDB is widely used in transportation, communications, finance, radio and television and other industries, with “hard power” for providing about 1 billion users in more than 20 provinces with 7*24 hours of real-time online services. Based on the AntDB database, Yunnan Expressway has also become the first unit in China to achieve the localization goal of the province’s high-speed clearing and settlement system.
