讨论了在IP网上实现多媒体数据传输时服务质量(QoS)的服务标准和服务种类,分析了IPQoS的体系结构:IntServ体系结构和DiffServ体系结构。在IntServ结构中重点分析了其核心协议RSVP,同时在DiffServ结构中着重分析了系统结构、核心路由器的服务质量和SLA。最后分析了IPQoS的现状及发展前景。
Discusses the service quality (QoS) service standards and service types for multimedia data transmission over IP networks, and analyzes the IPQoS architecture: IntServ architecture and DiffServ architecture. In the framework of IntServ, the core protocol RSVP is analyzed emphatically, and the structure of the system, the quality of service and the SLA of the core router are analyzed in the structure of DiffServ. Finally, the status quo and development prospects of IPQoS are analyzed.
