摘要
采用混合方式的网络拓扑结构和内部网桥技术，以低廉的投资实现了一个网络覆盖范围较大、能跨越多栋办公大楼的小型局域网络。该网络电缆距离的延伸较长，布线灵活，网段间隔离性好，不仅可以提高网络传输效率，易于检测判断故障，而且运行安全可靠。
A larger network coverage is realized by the mixed topological structure and the internal network bridge technique.This network system possesses many advantages.For example,it can extend the network a long distance,increase the transmission officiency and operate safely.
