Multi-tier Architecture for Service Creation, Deployment and Management
Customers now expect advanced IP services like video conferencing and application rental become customizable and easy to use. So, network service providers must be able to dynamically deploy such Internet services fitting the requirements of service customers while avoiding the expensive solution of over-provisioning the service. However, the current Internet technologies are lacking when it comes to developing and deploying new services, integrating together service offerings. This paper presents a service architecture which enables the creation, on-demand deployment and management of advanced IP services using the active network capabilities. In our approach, each business IP service is considered as a composition of basic service components which can be shared among different business IP services. Upon the requests of service users and Service Definition information, initialized by providers, mobile code is downloaded into active nodes and installed in the network as new basic service components. Finally, this paper presents the implementation of a Content Delivery Service using our proposed service architecture.
