共享缓存式以太网交换机缓存结构分析

Buffer Structure of Shared-Memory Switch

  • 摘要: 针对共享缓存式交换机能提供理想的吞吐量、延时性能和对于一定的丢失率共享缓存交换机需要的内存较其他交换机小的特点,结合现有的共享缓存式以太网交换机芯片,对该交换机的缓存物理结构、数据结构进行分析和总结,并提出了一种共享缓存式以太网交换机缓存结构。

     

    Abstract: Shared-memory is a common structure of Ethernet switches. It can achieve the optimal throughput and delay performance. Furthermore, for a given loss rate, a shared-memory switch requires less buffers than other switches. This paper analyzes and summarizes the physical and data structure of shared-memory Ethernet switches according to existence shared-memory switch chips, and bring forward our new structure.
