局域网是一种通常局限在一定区域内的专有网络。虚拟局域网可以将一个简单的物理网络段分割成多个较小的逻辑子网。虚拟网限定了广播域,改善了运行和安全性并理想的将信息技术系统和工业自动化系统分隔。
A local area network is a proprietary network that is usually limited to a certain area. A virtual LAN can split a simple physical network segment into smaller logical subnets. The virtual network defines the broadcast domain, improves operation and security, and ideally separates information technology systems from industrial automation systems.
