In this paper we present a novel business process aware semantic QoS provisioning scheme that accounts for the dynamic requirements and permits application-independent usage. The definition of a certain level of QoS using the existing models is just driven by technical aspects of the running applications. The provisioning of a certain level of QoS according to the requirements of an entire business process can hardly be accomplished using existing QoS provisioning schemes because these do not account for the dynamic requirements introduced by business processes. Each business process includes several tasks which have different priorities expressing each task's relevance in helping to achieve the related business objectives. The execution of business processes is supported by running many applications within a corporate network. Experiment results shown that it is necessary to guarantee QoS for real-time applications on crowded networks, and mobile user could get the same QoS guaranteed after it performed handover on QoSPCM
DIFF DERV SIP DEFINITION SOFTWARE
Voice software and DiffServ mobile IPv6 test-bed are implemented to demonstrate the validity of QoSPCM. Roaming users can keep communications with QoS guaranteed right after it performed handover. QoSPCM uses differentiated service (DiffServ) to guarantee QoS on wired backbone. SIP is extended to perform AAA processes and distribute QoS parameters. A QoS pre-configure mechanism (QoSPCM) is contributed to guarantee quality of service (QoS) on DiffServ based mobile IPv6 networks. Mobile IPv6 is a best-effort services model and QoS solutions for real-time mobile applications are needed. Mobile IPv6 is proposed to remain a device reachable even when the device roams away from one network to another on single-hop wireless networks. The future wireless network would be based on IPv6 to provide services for more users. IPv6 is the next generation IP protocol to solve the lack of IP address problem and it has been widely used on Internet.
