摘要 为了在区分服务(IP DiffServ)网络中实现有差别、可定制、有服务质量(QoS)保证的业务,改进了DiffServ分层业务模型;提出了完整的基于服务等级协定(SLA)的IP业务实现机制,解决了客户服务等级规范(SLS)到提供商SLS的映射问题;描述了IP业务实现流程.原型系统的实现验证了该机制的有效性. In order to implement the differentiated, customized, quality of service '(QoS) guaranteed service in IP DiffServ network, the layered service-oriented model for DiffServ is improved. An integral IP service implementation mechanism based on service level agreement (SLA) is proposed. Thus, the problem of mapping customer service level specification (SLS) to provider SLS is solved. An IP service implementation process based on the above mechanism is described. Implementation of a prototype verifies that validity of the mechanism.
