从局域网线路故障规律讨论网卡的改进

摘要

In this paper, the line fault in the local area network of Neijiang Normal School' s student dormitory is researched. The conclusion is obtained that the majority of network line faults are due to the bad line contact. On account of 4 lines idle in the network cable, a new idea is put forward that the correspondence information could be transferred again through the 4 idle lines. As a result, a new design for NIC is introduced, and the principle of its work is presented as well.%通过对内江师范学院24幢学生宿舍楼局域网线路故障规律研究,得出了大部网络线路故障是由线路接触不良造成的结论.针对局域网网络线中只有4根线在使用,有4根线空闲的情况,提出了让空闲的4根线也用来发送和接收数据这一新观点,并介绍了相应的新网卡的设计方案以及工作原理.
