适用于下一代网络的中间件技术研究

Research of middleware technology for next generation network

下一代网络将是一个统一、综合的网络 ,综合了分布式计算和通信技术 ,且应用种类较多 ,网络环境复杂 .旨在适用于下一代网络的中间件作深入的研究和实践 ,将常规中间件和移动中间件相结合 ,建立统一的中间件平台 ,并采用端到端服务质量技术、上下文感知和反射技术 ,为应用提供灵活的编程模型 (突破C/S模型 ) ,以及对动态环境良好的自适应能力 .且能方便地提供不同质量的应用 ,也使得开发、部署和管理这些网络应用的代价最小 .

NGN (next generation network) will be a uniform and integrated network which imports distributed computing and communication technology. NGN has multiple kinds of applications and network environment. Middleware for NGN was studied and practiced. Traditional middleware and mobile middleware were integrated together to provide uniform platform. End-to-end quality of service technology, context aware technology and reflective technology were used so as to achieve flexible programming model (beyond C/S model) and self-adaptive ability in dynamic environment. NGN middleware can provide applications with different QoS (quality of service) and can minimize the cost for developing, deploying and managing network application.
