一般是背板带宽和包转发率都满足的交换机才是合适的交换机。背板相对大、吞吐量相对小的交换机，除了保留了升级扩展的能力外，就是软件效率/专用芯片电路设计有问题；背板相对小、吞吐量相对大的交换机，整体性能比较高。摄像机码流影响清晰度，通常是传输的码流设定(包含了编码发送及接收设备的编能力等)，这是前端摄象机的性能，与网络无关。通常用户认为清晰度不高，认为是网络原因造成的想法实际是个误区。根据上面的案例，计算：码流：4Mbps接入：24*4=96Mbps1000Mbps4435.2Mbps汇聚：170*4=680Mbps1000Mbps4435.2Mbps接入交换机主要考虑到接入到汇聚之间的链路带宽，即交换机的上联链路容量需要大于同时容纳的摄象机数*码率。
