Abstract: In order to improve the efficiency of quality of service（QoS） management for the next generation Internet, mobile agents flat structure (MAFS) based on MPLS and mobile agents, used QoS object option(QOO) and flat management theory, enhanced the management mechanism of QoS, is proposed for mobile IPv6. In this scheme, MAFS reduces the layers and the number of mobile Agents、the costs and the transmitting time of signal, enhances the efficiency and flexibility when handoff occurs frequently, provides more efficient QoS management comparing with HMAT.

Key words: mobile agents flat structure, quality of service object option, resource reservation protocol, multi-protocol label switching
