Application of CDN Technology in Financial Network (Pick)
Abstract The feasibility and prospects of CDN technology in commercial banking networks are introduced. Key words CDN technology financial network application my country has joined WTO, commercial banks will directly face competition for foreign banks, and bring new opportunities, challenges and risks to banks while withstanding pressure. In order to adapt to the development of new situation, commercial banks are accelerating the pace of information construction, enhance their competitiveness and service level to make their own market share. Currently, all commercial banks basically have established their own communication networks. However, financial companies continue to appear new business, such as data concentration, e-commerce, video conferencing, online training, etc., and the demand for bandwidth is endless, but bandwidth expansion will be limited by the cost. How to better use limited bandwidth to provide unlimited business opportunities for the development of enterprises? How to further excavate the value-added services of existing networks, close the bank and customers, so that customers have everywhere to have no financial services, retain old customers in the market competition, develop new customers? In this case, the CDN content transmission network came into being. CDN is also known as the content networking, which is efficiently and personalized by high-level network intelligence to transmit the required content. CDN is built on the IP network, providing the end-to-end content service capability of the fourth layer of the bank network to the seventh layer, providing better services by optimizing the user's access. The CDN can copy the content to the most edge of the network, which is reduced to the minimum between the content request point and the response point, thereby shortening the response time, and increasing bandwidth utilization; CDN can also analyze the content of the user request, intelligently Scheduling and distributing resources, best utilizing resources. CDN's so-called content is actually synonymous with information, with rich performance forms, such as web pages, image files, video files, sound files, advertisements, training materials, conference materials, reports, etc. CDN mainly includes five elements: content distribution and management, content routing, content exchange, content edge transmission, smart network services. Optimizing the performance and bandwidth utilization of each application system, commercial banks can use online training, customer self-service, etc. to deploy high application to every branch office and outlets, which is not alone on the network platform or application platform. What you can solve, but need to rely on the network platform, build a smart content service platform, that is, the so-called content transport network CDN. This platform is between the application layer and the network layer (as shown in Figure 1), providing global content distribution, management, and routing services for the upper application, can control and optimize the application of the application for the network, improve the network platform. Efficiency, enriching the function of infrastructure. CDN is mainly for bandwidth, response speed, performance, scalability, reliability, not only optimizing network performance, improving application efficiency, integrated content resources, can provide services for multiple applications, especially multimedia applications. Figure 1 Financial Network Hierarchical Graph Construction A intelligent content platform combined with a unified network platform, supplemented by management systems and security systems, they mobilize, coordinate operation, in order to provide a perfect infrastructure platform for the upper application system. CDN is an emerging technology that is quickly accepted by large enterprises and telecom operators worldwide. Not only the traditional telecom operators have launched CDN services, but even a large number of CDN professional operators, specializing in the business and services of CDN networks. In fact, many financial enterprises have adopted some of the technology of some load balancing and content distribution, and the system has played a certain optimization. However, the application of these technologies is also partial, dispersed, and has not been consciously used as a complete architecture and application platform, which is also the vision of the future CDN development. Since CDN technology is based on TCP / IP protocol, it has been fully applying in major websites. And most bank trading systems are IBM-based large hosts, using SNA protocols.
