'Performance Evaluation of Mobile Agent Technology for the Configuration and Auditing of SLSs in DiffServ Enabled IP Networks'

摘要

Nowadays we witness a growing interest for the efficient management of the QoS delivered by the service providers to the Internet users and the usage of SLAs. In such an environment the need to maximise customer satisfaction and reliability and consequently, the deriving obligation to quantify and measure service functions becomes apparent. As traditional centralized NMS manageragent approach has stretched to its limits, we propose a way of bringing together the static nature of SNMP protocol with the Mobile Agent Technology (MAT) in IP network. In order to address lack of quality of service inherent in current Internet technology, we have chosen differentiated services architecture by implementing the corresponding DiffServ MIB proposed by IETF. The major objective of this paper is to compare the required time to configure and monitor DiffServ domain routers by using MAs and the client-server model. The results drawn from our research lend support to the claim that the performance enhancement by adaptating MAT to rigid network management area depends mainly on the traffic load on the link connecting the managed network with the manager.
