| 摘 要： | 该文提出了一个基于SLS的EPON的边到边QoS管理机制。通过EPON很好地解决了带宽不足问题;通过优化度评估算法为用户业务选择业务类。由于优化度评估公式基于用户在市场上的行为,考虑了负载、价格和性能因素,因此不但可通过引导业务量沿不同的业务类有序分布在DiffServ机制下实现了对用户业务的定量的边到边QoS保证,同时可以提高用户业务的性能价格比。实验结果很好地证明该机制的优点。 |

| Abstract: | This paper addresses a Service Level Specification (SLS)-based quantitative edge-to-edge QoS managernent mechanism in access network. By using Ethernet Passive Optical Network(EPON), it well settles the insufficiency of bandwidth in IP, it selects a service class for user service by the evaluation algorithm of optimal ratio, because the evaluation formula of optimal ratio is based on the user behavior in market and takes into accounts burden element, price element, and performance element, it not only can support quantitative QoS in DiffServ by inducing traffic orderly distributed along the service class, but also can provide well performance with less cost. Experimental results have perfectly verified it's metrics. |
| Keywords: | Edge-to-edge QoS management Ethernet passive optical networks DiffServ Service level specification Media access control |
