| 摘要: |
| 提出一种面向区分服务网络确保转发的覆盖式拥塞管理方案,基本思想是利用控制分组在网络的入口和出口节点之间传递网络服务质量的状态信息,入口节点利用加性增加和显性降低的算法调节聚集通信量的发送速率.实验结果表明,与标准的区分服务网络相比,该方案能在聚集之间公平地分配带宽并能显著地降低分组丢失率. |

| An Overlay-Based Congestion Management Mechanism in Differentiated Services Networks |

| Abstract: |
| An overlay-based congestion management mechanism for assured forwarding in differentiated services (DiffServ) network is presented in this paper. In the proposed scheme, a control packet is sent from the ingress to the egress router every fixed time interval. The ingress router employs a simple additive increase and explicitly decrease algorithm to adjust the aggregate's sending rate according to the QoS (quality of services) information reflected from the egress routers. For the performance evaluation of the proposed scheme, the simulation of the (proportional) fairness of aggregates traffic and packet loss ratio is presented. |
