The emergence of the Internet has changed the way people live and work, but also to the securities brokerage industry has brought new opportunities and challenges. Since March 30, 2000 the Commission issued "Interim Measures for Internet securities commission", the online securities commission as a new generation of securities trading in China has been rapid development of all types of online securities brokerage services website has emerged . Some online brokerage accounts, investors accounted for the proportion of the total number of corporate clients has reached more than 30%, online stock trading company stock accounted for 20% of the proportion of the total over.
Site construction is carried out on-line securities firm technical foundation for business transactions. As the business expanded, the site traffic increases exponentially, this time, access speed often becomes the bottleneck constraining business expansion, users can no longer tolerate the click of the mouse, then you can go for coffee to wait for the next page appeared. This site is slow like snail unable to retain customers. So every second counts in the securities trading industry, he soon moved to go to your competitor.
To solve the problem like this, there were many technical. For example, Web Cache technology to access the pages remain in the Cache, the next visit can be directly read out from the Cache; server load balancing technology (Server Load Balancing, referred to as SLB), so that multiple servers share the workload; GSLB technology (Global Server Load Balancing), to sites in different geographic locations automatically balance the load; SSL accelerator, replace software with hardware, so that SSL encryption and decryption faster; and so on. The emergence of these technologies will undoubtedly bring the gospel to securities companies, but also brought new problems.
The program to address speed and safety of brokerage sites, while there are two problems:
1. Brokerages huge investment. Each use of a technique, a device on the increase. To improve the reliability of the whole system, all equipment must have a redundant backup system costs high. Figure 1 does not paint the situation of multiple mirror sites. If you are using this program for each site, the site of the construction investment is amazing.
2. Management and maintenance complexity. This is undoubtedly a large number of devices in the test site management and maintenance personnel skill level and work patiently. With various different vendors often not dealing with a very pleasant thing.
Online trading business, the urgent need for a rapid development of new technologies not only accelerate the use of the above, protect website, but also reduce investment, reduce the complexity of the new solutions.
Liming Network Limited launched a solution to the problem of new products and programs. The core of this program is called "ClickArray" site accelerator. The product will integrate these functions to a device, a device to achieve the above functions. This realization is not to make a simple superposition of the above functions and packages, instead of using the new technology, new system design, not only greatly reduces the cost of the investment brokerage firms, reducing the system size, lower system failure rate, to facilitate the maintenance and management, and speed up the program with the traditional site greatly improved performance compared.
ClickArray Web Accelerator includes network load balancing, SSL acceleration, server-side Cache service, cluster service, seven function, and its Web application acceleration and Web security covering all basic areas of prevention. High degree of integration to enable them to abandon the complex network environment and numerous network devices, reducing the number of equipment brought by the network delay time, simplifies the network environment, more convenient and flexible extension upgrade.
ClickArray Web Accelerator main functions are:
1. Server Load Balancing (SLB)
Support the fourth and seventh floor of the server load balancing. By including the round robin, least connections, shortest response time, IP hash algorithms and content-based URL, host name, Cookies, including a variety of load balancing algorithms. Truly rational, intelligent server load distribution. Using connection pooling technology to increase resource utilization, the number of servers can support up to 1000.
2. Global Server Load Balancing (GSLB)
By Robin, overflow, and close to the priority of the algorithm, in different regions between the different sites for effective load balancing, and effectively improve network reliability and performance.
3. Reverse Proxy Cache
Up to 2GB of server-side reverse proxy Cache, the contents of each visit, while the issue of preservation to the Cache in the next use to speed up the Web site access speed, reducing the Web server's CPU utilization.
4. Web Security and Protection
Through the built-in security mechanisms to protect Web servers from hackers, can reduce the need for firewall site purchased separately.
5. SSL acceleration
Integrated high-performance dedicated SSL hardware accelerator card, 128-bit SSL encryption hardware to provide fast SSL security to encrypt and decrypt.
6. Cluster Technology
ClickArray Web Accelerator support clustering technology, can seamlessly increase the system capacity and availability. Once the cluster has a device fails, the other machines to take over its work immediately, and re-adjust the load. Can support up to 32 units of the cluster, performance can be as high as 16Gbps.
7. Content redirection
ClickArray Web Accelerator support content redirection, can delay, packet loss rate and other indicators will redirect HTTP requests to content distribution network (CDN).
