Computer interconnection is the principal object and the major application of Ethernet technology.
In early Ethernet LANs, computers were connected through coaxial cables to access shared directories or a file server. All the computers, whether they are servers or hosts, are equal on this network.
However, because most traffic flows between clients and servers, the early traffic model led to bottlenecks on servers.
After the introduction of full-duplex Ethernet technology and Ethernet switches, servers can connect to high-speed interfaces (100 Mbit/s) on Ethernet switches. Clients can use lower-speed interfaces. This approach reduces traffic bottlenecks. The modern operating system provides distributed services and database services, and allows servers to communicate with clients and other servers for data synchronization. 100M FE cannot meet the bandwidth requirement; therefore, the 1000M Ethernet technology is introduced to meet the requirements of the modernized technology.
