Distributed Futures Trading Platform And Achieve

With development of the computer network technology, there is a great change in the trade model of the futures, securities and stock Exchange in local and oversea market, that is, the electronic-trade has become the main trade model. In electronic-trade system, high performance and high availability are the most important characteristic.Based on the multi-tier distributed system, the paper discusses the design and implementation of the swpf2.5 futures-trade platform. We will use many AP servers to deal with the trade request respectively, which makes a load balance and extension demand, while an Access Server will be provided to the user to take charge of the load balance and system supervision. When a client login, he connects to Access Server first to get an available AP Server, then communicates directly with the AP Server. This makes a high performance trade platform, and it is easy to add AP Server to improve the performance.To implement the trade platform, we developed our Message Oriented Middleware(MOM)and Main Memory Database(MMDB) with good scalability and high performance to divide the AP Server, Access Server into different processes. In order to improve the availability, AP Server uses Master-Slave backup, and Access Server the Hot Standby Redundancy, so the service is continuous.The study will firstly introduce the architecture of distributed system and the main technology to build a distributed system. Then, the second chapter will analyze recent futures trade platform, based on which, the swpf2.5 futures-trade platform with high performance and high availability will be proposed. After the proposing of new platform, we make a detailed analysis of some important components in the platform such as Access Server, MOM and MMDB. Finally introduce the high availability of the platform, mainly the data replication and Failover.
