Abstract

Distributed Business Network (Distributed Service Network / DSN) P2P technology into the telecommunications network, has become a hot research content of the communication network. DSN can be seen as based on a common hardware platform for the Internet business and telecommunications business of large-scale distributed business systems. Although the design and implementation of the DSN is considering new business To be able to support the integration of telecommunications networks and the Internet, but at the same time should first be inherited and is compatible with existing business seamlessly, and these include a number of translation class business. The number translation class business \From the beginning of the introduction of the DSN architecture and functional entities focuses on the design and implementation of number translation class business server. Firstly, for example, to VPMN and Google Voice number translation class business successful commercial application, the definition of the concept of number translation class business and business characteristics, and design as number translation class business server demand basis. Number translation class business the number translation class business server location and function of the structure in the DSN, focused on solving the problem of the connection between business server and distributed core network business servers and core network decoupling, so that the business server like application servers on the Internet, convenient deployment, replace or uninstall without affecting the operation of the core network. In this paper focuses on the the Number the translation class business server design, including the critical part of the interface design, process design, state machine design and database design. Number Translation class business server implementation and content of the test is also the focus of this article. MCF (Message-driven Component-based Framework) software development framework the number translation class business server-based implementation of complex telecom applications software development, simplified to the description of the finite state machine and the state deal with the preparation of the code. The MCF introduction not only greatly simplifies the complexity of application development, reduce workload, greatly improve the stability and availability of the software. Finally, a series of tests to prove the the number translation class business server design and implementation of this article can be achieved not only needs analysis given the features, but also have a higher availability.
