Description

technical field [0001] The invention relates to an Ethernet network, in particular to an Ethernet signal processor and an Ethernet signal processing method. Background technique [0002] With the popularization of the network, various network devices emerge in endlessly. The most common network devices today include hubs, repeaters, switches, routers, and gateways. These devices typically process data at one or several layers of the OSI reference model (see figure 1 ). [0003] Repeaters play the role of signal relay and amplification in today's networks. However, with the increasing popularity of network devices such as hubs and switches, dedicated repeaters and repeater chips are hard to find. In many networks, hubs are usually used to achieve signal relay and amplification. [0004] see figure 2 , which is a schematic diagram of the principle structure of the Ethernet. It includes several Ethernet nodes 11 (such as: Ethernet node A and Ethernet node B) and a networ...
