我们在选购网卡时,往往会看到很多网卡标明自己是10/100M自适应网卡,那么,这种“自适应”究竟指什么?在实践中的效果又如何呢? 自适应(Auto-Sense或Auto-Negotiation)技术是指网卡可根据与己相联的周边设备按照先100M全双工,然后100M半双工,接着10M全双工,最后10M半双工的适应顺序,自动以最高速率和最佳工作方式连接。 在实际应用中,我们发现并不是所有的自适应网卡都能“自适应”周边的连接设备,在一些采用自适应网卡的网络节点上, When we buy a network card, you will often see a lot of network cards that they are 10 / 100M adaptive network card, then what does this “adaptation” mean and what is the effect in practice? Auto-Sense Or Auto-Negotiation) technology refers to the card can be associated with its own peripherals according to the first 100M full duplex, then 100M half-duplex, then 10M full-duplex, the last 10M half-duplex adaptive sequence, automatically at the highest rate And the best way to work. In practice, we find that not all adaptive network adapters can “adapt” to the surrounding connected devices. In some network nodes that use adaptive network adapters,
