We have developed a network testbed GNET-1 so as to observe network traffic, emulate networks and test communication protocols. GNET-1 is provided with four Gigabit Ethernet ports and four high speed RAM banks which are connected to a central large scale FPGA. GNET-1 emulates more than 100 ms delay, which is corresponds to that of a wide area network, and a single frame discard on full speed of Gigabit Ethernet traffic. We can easily add new functions, such as bit error generation and frame header trace by re-programming the FPGA.
