mtu 1500表示最大传输单元(Maximum Transmission Unit)为1500字节。这是网络接口可以传输的最大数据包大小。如果数据包超过这个大小,它将被分片传输。 qdisc pfifo_fast: qdisc pfifo_fast表示该接口使用pfifo_fast算法进行队列调度。队列调度算法(Queueing Discipline, qd

标准MTU:通常为1500字节,适用于大多数以太网环境。 Jumbo Frame MTU:可以支持更大的数据包,通常为9000字节,适用于高速网络环境。 四、应用场景 VPN连接:在使用TUN设备构建VPN时,调整MTU可以优化数据传输效率。 数据中心内部通信:在高速网络环境中,使用较大的MTU可以提高数据传输速度。
