A QoS management architecture for DiffServ-aware MPLS-based IP network

The DiffServ-aware MPLS-based QoS architecture has become one of the most promising ways to guarantee QoS in multi-service IP networks. But how to manage IP network with QoS guarantee is still an open issue. In this paper, a policy-based QoS management architecture for DiffServ-aware MPLS-based IP network is presented. The overall structure of the architecture is described and each submodule is itemized in detail. The implementation experience of the work is also addressed.
