Research on NGI/NGN Architectures and their QoS Provisioning Mechanisms
NGI／NGN体系结构及其服务质量保障机制研究

This paper focuses on architectures of the Next Generation Internet/Network and their QoS provisioning mechanisms based on a comprehensive review of existing activities of relevant topics. A framework on NGI architecture called SUPA under development at Sichuan Network Communication Technology Laboratory is presented to demonstrate possible transition from current Internet to NGI with better QoS provisioning.
