Sales Of Securities With The Securities And Exchange Exploration And Research Network

With the increasingly fierce competition in securities industry, the requirements on network performance are higher and higher. How to create a highly integrated and digital modern high-performance network with high scalability, high security and high-bandwidth has become a key issue for the overwhelming majority of firms in their long-term and stable development.For the network of securities exchange system, stability comes first, followed by high availability. In 1989, Shanghai Stock Exchange and Shenzhen Stock Exchange opened one after another, thus the stock market entering Chinese people's lives, and the stock market becoming a new investment. Particularly in recent years, more and more people participate in stock market investment. Due to the sharp increase of sites and the irrational network structure, the original computer network systems in many securities exchanges are overloaded. The speed of checking the ups and downs of stock market, the speed of commission and the rate of return have failed to satisfy the needs of customers. Therefore it is essential to redesign and completely transform those old-fashioned technologies of computer network systems.Therefore, taking one stock exchange as an example, this paper first specifies the process of stock exchange, according to which the existing technological problems are pointed out, and a further detailed discussion of how to solve these problems in designing the network of stock exchange is carried out, and finally a typical practical example of designing a network for a stock exchange is given.When designing the network construction for securities exchange programs, the following are taken into account: the high reliability and efficient operation, the future conduct of value-added services, such as wide-area network interconnection among business department, sales departments'access to the Internet, on-line Internet transactions, and so on. It will fully embody the basis of a good, unique securities exchange network which is secure, real-time and with a high performance-price ratio.The program is based on the building of new addresses so that the network has a good scalability which enables users to easily expand. This program, according to our own conception of network development, as well as the tender requirements, provides a complete network security solution for networks to provide users with more choices, allowing users to have a clear blueprint of the development plan of their own network. According to their own circumstances, users can carry out a phased implementation and finally establish a secure, stable, reliable and full-featured network.This construction of the stock exchange involves the construction of 400 information points and engine rooms to create new network architecture.The orientation of stock exchanges in network should take into account the development of network technology; we believe that the choice of Gigabit Ethernet technology is an inevitable choice in the development of the enterprise network.First, the gigabit network technology has become mature and Gigabit products will be the mainstream products on market;Second, for any enterprise, the gigabit network can easily solve the network "bottleneck" problems.Third, it can protect the investments and provide adequate security for the development of stock exchanges so that there will be sufficient bandwidth to expanding and to increase network nodes or the business volume.Fourth, Fast gigabit network switch has a higher bandwidth, more processing power, with a faster rate of exchange, and the speeding up of the backbone of the network of exchange rate is bound to increase the speed of the entire network.Fifth, the performance of current servers continuously improves, and Gigabit Ethernet has been widely used in place of the original card Fast, removing the restrictions brought about by the card on the server performance. It has a higher on-board cache (Buffers) and a CPU chip, reducing interrupt request by the transmission network to the server's CPU and greatly reducing the burden on CPU.In current securities industry, brokerage has further improved the reliability of the server market, and the principal means of achieving reliability is to use a wide range of sophisticated technology and easy-to-use backup strategy. So far, there are many back-up schemes of market server which firms have used, including Novell NHAS, Vinca Standby server, Novell SFT III, NovMate 2000, two-Longsheng. But with the rapid development of computer technology, some technologies have been gradually eliminated; some are due to too complicated technology, which, if implemented, will bring about additional risks; some are due to the too strict dependence on hardware and are not suitable to be used in the stock industry. So it is crucial to select a suitable backup strategy for the stock exchange.Due to the important position backup data occupies, it has become a relatively independent branch in computer field. In general, a variety of operating systems attached to the back-up procedures have shortcomings of one or another, so if reliable data backup is needed, specialized hardware and software must be chosen and corresponding backup and recovery program must be developed.After a comprehensive study on the hardware and software products and an in-depth analysis of a variety of back-up programs, this scheme is put forward. We are trying to provide you with a complete, intelligent and easy-to-manage data backup which is simple and with reliable disaster recovery mechanisms so as to protect corporate data systems.This article first describes the process of securities exchange, according to which the technical problems in trading are identified, a further detailed discussion of how to solve these technical problems is carried out, and finally a typical example of designing securities exchange network system is given.The tasks completed in this subject mainly include:(1) Research and analysis of the existing securities exchange network topology to identify the constraints on network efficiency. (2)Two Catalyst 4006 constitute the core of the network layer; Cisco GEC technology (Gigabit EtherChannel) is used to connect the switches; GEC "tied up" 2 Gigabit ports to provide up to 4Gbps full-duplex channels; all Cisco's switches products support FEC / GEC. FEC / GEC can not only enhance the exchange between the interconnect bandwidth, but also can provide fault-tolerant between various physical links, making sure no arbitrary cut off will affect the smooth operation between switches.(3) Three security strategies are employed to achieve the network access security: Cisco switch ports using MAC address restrictions, the second floor of the network (data link) of the virtual network VLAN technology, and the third network (network layer) on the router's access list Access list.(4) NovMate2000 high-efficiency low-load incremental backup systems are selected to make customized and flexible backup strategy. It will not do damage to the database on backup servers.(5) In accordance with the requirements of the subject, an actual testing and an analysis of securities exchange networks are carried out, which proves that the designing of the network is indeed a success.
