Adaptive QoS Mechanism on the Next Generation Network
下一代网络自适应QoS研究

With the development of Internet technology, especially the conditions of wireless and mobility be migrated, more user's tasks with different QoS requirement will be implemented in Internet, this will make current network-level QoS guarantee not meeting future user's needs. However, adaptive QoS is the best way that solves future user's quality needs in wireless mobile environments. In this paper, for the future network conditions with heterogeneity, mobility, more covered links, more covered services and so on, based on the original object of QoS, which it guarantees use's personality need, we propose the concepts such as network-level, application-level and user-level, and then discuss future user demands characteristics, and detail adaptive QoS conception, studying ranges and basic architecture. Finally, we show our future work direction.
