| 摘要: |
| 宽带路由器一般采用crossbar交换开关。Crossbar交换开关对QoS（Quality of Service）的支持十分重要。提出一种支持IETF区分服务（Differentiated Service） 服务模型的crossbar调度算法——OSP（Output Serial Polling），该算法带宽利用率高，支持报文优先级。与目前存在的同类算法相比，具有硬件实现简单的优点。 |

| Abstract: |
| High performance routers often use crossbar switch. It is important to a crossbar switch to support QoS (Quality of Service). This paper presents a new crossbar scheduling algorithm-OSP(Output Serial Polling) which supports the DiffServ (Differentiated Service) model purposed by IETF. OSP algorithm can deal with cells that have different priority while achieving high crossbar throughput at the same time. Comparing other algorithms, OSP can be implemented more easily in hardware. |
