An address on the IPv4 protocol is defined using 32 bits, insufficient to support IP network applications. This issue becomes more complex when the number of UMTS/GPRS users increases to 10 billion or more on IP-based applications. The IETF Task Force defined the IPv6 protocol to solve this problem. An integrated research project “All-IPv6 Networks and Applications” was establishedto help to build an All-IPv6 application environment for the telecommunications industry. The aim of this project was to develop advanced technologies and systems for All-IPv6 networks, including the handoff scheme, mobility management, multicast service method, multimedia applications, security, and QoS guarantee. The developed technologies will be embedded into the All-IPv6 testbed. The feasibility of this system will be investigated using an open service platform. According to the functional requirements of this project, the research timeline is divided into three stages (phases). The first-stage project focuses on the design of the interworking system and high-quality data communication services for All-IPv4/IPv6 networks. Tasks include developing an interworking mechanism among GPRS, WLAN, IPv4/v6 Router, Core MPLS Switch and NBEN to support a “seamless transmission” environment. The GPRS Emulator & WLAN handoff service analysis, multicast service planning, media stream control, and the open service platform interface were performed. The second-stage project focuses on the design of All-IPv6 network and the service of highly efficient multimedia application. We established the "seamless transmission" environment and the pure IPv6 network. More achievements we finished, including the handoff service analyses of UMTS Emulator between WLAN and GPRS respectively, the seamless multimedia stream system of dynamic multicast, and the integration of open service platform and its APIs. The third-stage project focuses on the design of Mobile All-IPv6 network and the service of mobile multimedia application. Our tasks have completed the HPS packets scheduling technology for UMTS、the QoS framework of SSANQIM with QoS multicasting 、MIPv6 environment testbed 、IMPS (Instant Message and Presence Service) system、 OSGi-based gateway to integrate heterogeneous communication technologies used in today fast digitalized families. Also, through the construction of QoS Manager, we can reach the demand of QoS. This work will provide a “highly efficient” and “high quality” All-IPv6 network and application environment. More key modules, including an interworking scheme, a security module, a mobile agent, and various protocols for improving system QoS were developed. These modules will then be applied to the All-IPv6 network and applications to provide responsive information services. We believe that the results of this research solve outstanding technical problems in All-IP network establishment, handoff technology, wireless, mobility and high quality assurance. |
