基于Agent技术的QoS解决方案

设计了一种通过Agent技术实现Internet中QoS管理的可行性方案。在此方案中,将服务质量管理进行了层次划分,分别为:应用级(提供友好的QoS接口),系统级(优化应用级QoS,分配系统资源)和网络接口级(提供系统级QoS到网络级QoS的映象);设计了基于Agent的QoS管理抽象类(通过继承抽象Agent类,可以合理的构造出适合于QoS传输的各级代理);提出了QoS管理系统的体系结构以及支持这种层次结构模型的5种代理实体(UserAgent,ServiceAgent,SystemAgent,NetworkInterfaceAgent,NetworkAgent);讨论了代理的执行环境、代理间的通信与合作等问题。

A QoS Implementation Scheme Based on Agent Technology

A feasibility scheme by using Agent technology to implement Internet QoS management was designed. In the scheme, QoS management system was partitioned into three hierarchies: application level (supplying the friendly QoS interface), system level(optimizing QoS of application level and assigning system resources ) and network interface level(supplying a map from QoS of system level to QoS of network level). Subsequently, a QoS management abstract class based on agent (Every level agent to be fit for QoS transfers may be constructed reasonably by inheriting the abstract agent class) was devised. A QoS management system structure and five agent entities(User Agent,Service Agent,System Agent,Network Interface Agent,Network Agent)supporting the hierarchy model were brought forward. Finally, agent execution environment, communication and cooperation among agents were discussed.
