Service Level Agreement Driven Verification and Programming Framework for Quality of Service
Xingjun Zhang · Xi'an Jiaotong Daxue xuebao · 2010
A service level agreement driven system framework with quality of service(QoS) verification and programming is proposed to address the problems of the existing QoS-guaranteed service systems,such as low efficiency,bad scalability,and inadequate QoS automatic control.The framework is composed of Service Programming,Service Verification and Service Execution,and integrates functions of executive management with system services.The optimization of system monitoring and system management,and automatic QoS control are achieved through an automatic combination of services so that the problem of bad scalability is solved.Examples and experimental results show that the system framework for verification and programming of QoS can adaptively integrates functions of executive management for the dynamic needs of service composition,executive management and automatic QoS control.
