摘要

针对现有服务质量(QoS)保障服务系统模式效率低、可扩展性差、QoS自动控制不足等问题

提出一种面向服务级别协议的核实与规划服务质量系统框架.该框架包括服务规划、服务核实和服务执行3个功能模块

可有机地融合服务执行管理的系统功能和系统服务

并通过一种新的服务自动组合模式实现了系统监控与管理功能的优化

实现了QoS自动控制

由此解决了系统的可扩展性问题.实例与仿真实验结果表明

核实与规划服务质量的系统框架能够自适应地组合执行管理系统功能

使之适应服务执行的动态变化

满足自动组合带来的功能需求

最后达到了QoS自动控制的目的.

Abstract

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.
