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 service 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 platform 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 10.5 Mbps to 60.5 Mbps; the average response time increased from approximately 1 ms to 10.5 ms, and the delay time increased from 0.1 ms to 1 ms.
