3.3.2. 全模式的仿真结果

全模式或者数据包传输(packet transfer)模式下,流量发生器以随机次数的突发生成10,000个字,并在TX和RX链路建立后发送到IP。随后这些字被环回到RX MAC。RX MAC将突发发送到流量检查器进行数据验证。您可以在仿真结果中找到以下信息:
  • TX和RX链路状态
  • IP的配置设置
  • 每突发发送的样本字数
  • 测试结果,以及传输的总字数、突发数和链路延迟值

以下是每个设计实例变体的仿真结果示例。

全传输模式下使能RS-FEC的PAM4的仿真结果

注: 使能RS-FEC的NRZ变体具有与使能RS-FEC 的PAM4变体相似的仿真结果。
