摘要: |
研究并提出一种有效支持组播的高性能路由器QoS机制QoS_RESM,该机制以多阈值机制为基础,考虑远程转发引擎的拥塞状态信息,引入全局控制反馈机制,有效完成了高性能路由器上支持组播的流量控制。最后描述QoS_RESM在基于网络处理器的核心路由器上的实现方法。 |

Abstract: |
A new QoS mechanism with effective multicast supporting in high performance routers—QoS_RESM is presented and studied in this paper. Based on multi-threshold mechanism, it considers the congestion information of remote forward engines by introducing the mechanism of global control information feedback. It ends with a description of the implementation method of QoS_RESM in the core router on the basis of network processor. |
Keywords: multicast flow control congestion control high performance router network processor |
