Broad Sense QoS model for next generation Internet

摘要

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. However, user will front a network which state changes from the static to the dynamic, the QoS requirement will changes from the one for single network condition to the other for several heterogeneous. In the face of the complexity of the next generation network, traditional QoS concept model will not suit for this condition. In this paper, we propose a new QoS concept model QoS_w for the next generation network. In QoS_w, we define Network-space Ω_N and User-space Ω_U conceptions and analyze the mapping relations between Ω_N and Ω_U. We enlarge the scales of network QoS guarantee from the network-level for user's physical resource needs plus both the application-level for the application characteristics and the user-level characteristic for the user characteristics. Finally, the policy format of the QoS requirement can express better the semantics for user's needs, this will better adapt to the next generation network conditions and have a better expression for use's personality.
