Iris主要应用于Ethernet网,这是由Ethernet网的共享特征所决定的。在Ethernet网内，承载数据包的通道为本Ethernet网段的所有计算机所共享，而决定一台计算机是否收取一个数据，在于这个数据包是不是发往这台计算机的。每台计算机的网络适配器，也就是网卡都有自己独特的网卡地址。如果网卡发现一个数据包是发往本网卡地址的，它就会接收它，否则就丢弃它。-Iris is mainly used in Ethernet networks, which is shared by the Ethernet network characteristics determined. In the Ethernet network, the channel carrying packet-based Ethernet network segment shared by all computers, a computer to determine whether to accept a data packet is that it is not sent to this computer. Each computer' s network adapter card is the card has its own unique address. If the card found in a packet is sent to us the address card, it will receive it, otherwise it is discarded.
