摘要
Diameter是最新的鉴别、授权和记账(AAA)协议,它的规范统一性以及跨域能力使它更加适用于移动通信环境,它将成为未来AAA基础设施的主流协议。Opendiameter是由IETF管理的开放软件项目,用来提供Diameter协议的实现原型和C++API。本文分析了Opendiameter的体系结构和需要改进的地方,并对其体系结构进行了扩展。实际的移动通信项目证明,扩展后的体系结构具有实用性、高效性和稳定性。
Diameter is the newest Authentication, Authorization and Accounting（AAA） protocol, and its unified specification and inter-domain capacity make itself more adaptive to mobile communication environment so that it will be the major AAA protocol of the future. Opendiameter is an open software project supervised by IETF, providing implementation prototype and C＋＋ API for Diameter protocol. The architecture of Opendiameter is analyzed, with its insufficiency clarified. The architecture has been extended. Used for a mobile communication proiect, the extended architecture is proved to be practical, efficient and robust.
