摘要：
In mobile/wireless IP network where frequent mobility is encountered, it is required to accommodate internet Quality of Service (QoS) mechanisms such as Differentiated Services (DiffServ) for mobile hosts. In this paper, we consider the issue of integration of mobile IP and DiffServ including handoff condition and propose the schemes with hierarchical agent architecture for supporting QoS in mobile/wireless IP networks. To support DiffServ for mobile hosts, we configure foreign agent to have pre-allocated resources in advance for static Service Level Agreement (SLA) case. In case foreign network has no pre-configured SLA or enough resources for mobile host, we configure new SLA among bandwidth brokers to be set up using dynamic SLA. Also, we propose the signaling and data procedures with DiffServ with respect to fast handoff.
