千兆以太网帧识别的FPGA设计与实现

he development of intelligent has been an important direction in communications network. Although some research on intelligent networks has been started in recent years, these studies are far from people's needs of intelligent network. Frame distinguishing technology can locate the data frame, and analyze data content of the frame for transmitting and receiving. With the emergence, development and widespread use of Gigabit Ethernet, frame distinguishing in Gigabit Ethernet has become an important subject. This article first introduces the basic principles of Gigabit Ethernet.This paper presents the basic principle of Gigabit Ethernet firstly, then puts forward the blue print of the FPGA design of frame distinguishing at transmitter and receiver based on Gigabit Ethernet, at the point of frame structure described in IEEE 802.3. Stimulation results are given in the last part.
