Abstract: Service-Oriented Architecture (SOA) provides a solution for reengineering legacy systems to support distributed application environment. But due to the limitation of technology and architecture involved, issues such as nonsupport of a multithreaded environment, memory leaking, non-support of parallel environment still exist in some parts of the legacy systems, which restrict their applications immensely. Through analyzing and doing research on the communication mechanism of Windows Communication Foundation (WCF), a parallel architecture was proposed to solve these problems. The architecture improved the default architecture of WCF by adding a service controller to it, which could deliver message between the client and the server and selected service for clients. The proposed architecture has already solved these problems and been applied in a large financial system.
