Classic Network solution: smooth as water unimpeded

Project background

In recent years, with the increasing number of floating population, shijiazhuang increased water consumption, in order to effectively control the use of waste, advocating conservation-minded society, Shijiazhuang Water Supply Corporation urgently needs to further control the accurate information of the public water.

However, all along, Shijiazhuang water supply Company's water users charge system is the use of traditional centralized collection system, so can not accurately grasp the user's water information.

To this end, Shijiazhuang Water Supply Corporation decided to carry out the reform of the charging model: the traditional centralized collection mode into a direct to the end of the toll meter to the user model.

Although the new charging model can accurately reflect the water condition of each user, it is followed that Shijiazhuang water supply Company's original operating fee system can not be loaded due to the rapid increase in the number of users to bring the business volume, the formation of system resources, resulting in network congestion, and even data loss.

Therefore, the construction of new billing information system has become the most important part of the reform of Shijiazhuang water supply company.

Network speed poses a bottleneck

According to the new business needs, Shijiazhuang Water Supply Corporation to establish a new business billing information system to meet the monthly "600,000" yuan accounted for the user's payment needs.

By industry experience, the average window needs to be serviced by 1000 users, and 50% of the business terminals at the peak are trading with the database host. As a result, the number of operating windows can be estimated to reach 600, the number of concurrent windows at peak times is 300. Assuming that the response time for each transaction is not greater than 3 seconds, the total number of concurrent transactions per minute will reach 6,000.

And the existing network can not load 6,000 windows per minute data transmission, Network load capacity has become the most critical factor in system transformation. As a result of the use of the system more in the daytime normal working hours, during the 10 hours of the day there is no specific peak period, but the end of each month, the beginning of the beginning of the pay peak, the system utilization ratio is high, peak easy to form network congestion.

Network planning of operating fee system

According to the overall information planning of Shijiazhuang Water Supply Corporation, the operating fee system is divided into two parts, namely the database server part and the network part.

The core network equipment, placed in the head Office Information Center, Edge network equipment placed in the business office. These are all connected to the information center with a 2MB digital circuit. The revenue system will also be connected to banks to meet the needs of bank charges.

The router part and the bank-side access switch will be placed in the head office to complete the connection of wide area lines and the needs of the bank, which requires the function of accessing the backup line, that is, to enable the backup line in case of failure of the main line, to avoid the interruption of the revenue work.

The connection to the bank also has a strong security mechanism. The division is designed in a way that will have 5 points in the future. The main revenue server is placed in the head office, and the company has to exchange information with a strong security guarantee.

After defining the principles of network construction, according to the scale and speed of business development, accurate estimation of the network traffic demand in the next 3-5 years, after repeated comparison, selection and demonstration, finally selected HP Network's Adaptive Edge Architecture Enterprise network design concept and high-speed, secure network solutions and products.
