An intelligent network architecture based on active network technology

The emerging technology of active network is one of future directions of communication networks, where users can inject their programs into network infrastructure. The increasing number of supplementary services, the development of new types of services and several years of usage show some drawbacks of Intelligent Network (IN). This paper looks at impacts of active network technology on the traditional IN. We present a novel IN architecture enhanced by active network technology, which can not only overcome some drawbacks of traditional IN, but also keep the existing resources. We also describe how to support intelligent services based on active packets (capsules), which results in better performance and fault tolerance compared to traditional IN service implementations.
