All-IP convergent communications over Open Service Architecture

The application of IP (Internet Protocol) technology in the information and communications industry is a major global trend. A highly efficient set-vice architecture, enabling technologies and advanced applications are critical to rapid multimedia services in an All-IP network environment. In this study, an All-IP service plarform based on Open Service Architecture (OSA) was developed to support a set of standard interfaces and applications. The All-IP network environment was integrated using a network-processor-based IPv4//IPv6 translator and a mobile router (MR) supporting IP network mobility. The feasibility of the open service platform for All-IP network environments and of the designed application programming interfaces was investigated using three applications, e-commerce, video-on-demand and on-line gaming. The performance analysis demonstrates that when the number of users was increased from 1 to 80, the system throughput increased from 10.5Mbps to 60.5Mbps; the average response time increased from approximately 1ms to 10.5ms, and the delay time increased from 0.1ms to 1ms.
