To leverage VLAN tagging the operating system adds a VLAN ID tag to each TCP/IP packet.

为了利用 VLAN 标签技术，操作系统会给每一个 TCP/IP 数据包添加一个 VLAN ID。

The Net::TcpDumpLog module serializes each packet, so that we can read each packet by using the packet ID.

TcpDumpLog 模块会将每一个数据包序列化，这样我们就能够通过数据包 ID 读取每一个数据包。

The weakness in Internet Protocol is that the source host itself fills in the IP source host id, and there is no provision in TCP/IP to discover the true origin of a packet.

IP协议中最脆弱的策略就是让源主机自己填写源IP地址，并且在TCP／IP协议中也没有提供一种机制来验证源IP地址的真实性。
